Thanks to the help I got from Steve Cole today; the cooler is in and being tested in my truck. Steve got it pretty hot when he stalled the Ally for 15 minutes guessing at 2K. Temps jumped past the 200 mark and stopped at the first marker( notch past 200) when I left for a test. I drove streets for 2 and a half miles or so ( 45 mph then stop and so forth). Came back to the shop and temps dropped to between 200 and first mark below it ( promissing). None of this was a good test since we did not have a scanner on it and how many people would stall their truck so long. ( Steve Cole would and did. He is an animal http://www.dieselplace.com/forum/smileys/Big Smile.gif). I will post a picture monday.


mike


One more thing; I crawled under truck while 2K stall was being done and grabbed right cooler line and burned the sh*t out of my hand, grabbed the other line and I could hold it. http://www.dieselplace.com/forum/smileys/Big Smile.gif Promissing.

ive seen my trans over 200 a few times... is this really bad?

ive seen my trans over 200 a few times... is this really bad?





No. The trick is to keep it below 200 under any circumstances. The limit for the Ally is 259 deg before it goes into hot mode. That is the emergency program in the TCM that will comand TCC ( torque converter lockup) and you will not have control over it untill it cools down. I have not seen this limp, but I would expect an SES light when this happens. I have induced this program with my Mastertech and it is different than T/H. In this condition you will have lock-up in first gear.

Hey Mike,


When are you predicting this cooler to be public ready?http://www.dieselplace.com/forum/smileys/Clap.gif

Hey Mike,

When I am sure it works. I already know it is drop in. No mods, no cutting, no drilling, no fabricating. You pull the grill, disconnect lines, remove 2 bolts, to clips and temp sensor and its out. Reverse this procedure for my cooler.

Okay, I didnt know if you had a time frame yet or not, or maybe a cost. Just getting some info. http://dieselplace.com/forum/smileys/Wink.gif

try stalling my truck with the extreme- it got up to 230*+


its been so hot up here recently i've running at 200* all day long, sometimes just below the 210* mark if i'm antsy..

Did some testing this evening. I got stuck in traffic 92 deg for an hour. Temps never got above first mark under 200. I didn't expect to hit this traffic tonight and did not have my scanner on. I noticed that when the temps began to rise, they dropped just as fast when I got rolling. Ally now runs normal at below 150 deg. I also noticed it take longer to get to 150. I like the way it drops the temps after it gets hot. Stock cooler took forever. I am looking for a 20 deg drop. It looks pretty good right now. More testing to come.


mike

Hey MikeL, would 2 more stock coolers in series be up to this task?


Or 2 stock coolers and a fan?


There would be some increase in efficiency with the added radiant surfaces wouldn't there?

Another stock cooler would help. A fan would help also. I think it would be a lot of work modifying cooler lines for an additional cooler. Five eigths inch lines are tuff to work with. I will stick with my cooler because it is simple. How many times have we bought something that did not fit? We then asked a proffesional to help us, and were given the answer " why did you buy that piece of crap?" So we threw it in the corner of the garage and within a year tossed it. I won't have that. 30minute install sober, 45 with a beer, the rest is up to you guys. http://www.dieselplace.com/forum/smileys/HiHi.gif

Mike,


Get Diesel Tech to load the Tow program back into your truck. Take the truck up in the hills around Palos Verdes on a warm day. Find slow stop and go stuff. I you want to really test it, head inland on a 100 degree day and repeat the stop and go driving in the hills. This drives the tranny temps through roof (and they don't recover for a long time on a truck with the stock cooler). From my experience, the above scenario is worse than driving across the desert pulling a travel trailer in the summer time.


Alan

You have the deep pan mike?


I have the deep alli pan and you are right about the stocker, it takes forever to bring the temps down. Actually the only way to get the temps down is to run it down the highway for awhile, once it gets up there in town even if its light traffic its staying a shade under 200 in my experience regardless of playing nice or not.

Mike - send one my way for testing when youre ready, im towing my toy hauler the next 3 weekends in a row in 100* heat, in and out of towns, up and down mountains into nevada from sac and might even be towing it down to your neck of the woods for a race.

Drop me a line when it's ready. I don't think that I NEED it, but when a guy starts running quick acceleration trials, especially with an unlocked converter, it can hit 200-210° pretty quickly. Should help bring it back more quickly if it even gets up there.

What is the max temp with out causing damage.

After 225 you are on the hyway to hell. 259 kicks in the hot mode where the TCM says thats it, we are in big trouble and gives you uncontrolable lockup in every gear for cooling. IMHO you are safe at up to 225 with synthetic fluid and I would recomend fluid changes at 15K with synthetic. ( I am anal and over protective and don't trust anyone or anything). I am changing a lot of my past thinking now that I am testing temps and seeing what really goes on. The stock clutches are not a concern because they are dynomite ( without programs or racing and Transgo). I am worried about the rubber molded pistons keeping soft and plyable under heat, and Dexron 3 won't cut it. Transynd, Amsoil, Mobil 1. There are other good synthetic fluids out there, please use them.


mike

you know if your engine temp is near 200 when you stop and go the flow of air subsides.....Does the radiator heat up the cooler?......are they not stacked right close to each other.........how bout a rear mounted cooler with a fan

sdaver


I have never seen my truck ( engine) temp go any higher than a tad below 210F ( where it always seems to be warmed up) under any circumstances, so I don't think its a big contributor to heat. The 260 psi in the Ally, and AC full blast, and converter clutch being off contribute to heat big time. Sat. on the way to TTS, I was challenged by 2 different " heemis" on the freeway so we played around between 60 mph and 90mph. I found both of them lacking after 85 mph but did notice my Ally temps jumped ( I was out of lock up)after playing around, so Kennedy is right on with his observation. I think a second cooler would help, for you guys that are thinking of doing it, a fan mounted on the cooler will also help. Once my cooler is tested and done, I may have a fan option with manual control ( switch). I don't like the thermostat control because they always kick in too late.


mike

And Sdaver makes it to 1000 posts!

Speaking about tranny cooling... When I installed my transgo kit and suncoast TD, I broke one of the tranny cooling line connectors for the tranny. I ordered the part with my VIN # to be sure and I got connectors that are "biger". What I mean by that is that they fit the coller lines perfectly but the tranny side is too big for the hole in the tranny. After multiples verification and re-ordering, I kept receiving the same "wrong" part for my tranny.

I had to install 2 other adapters to fit it in and now the whole cooling line had shifted very close to the exaust and is more than 5-6 inches long wich may provoke some breakage because of the lever effect.

The various adapters have smaller holes and induce limitation in the flow of tranny fluid to the cooler wich in turn puts more heat on the tranny.

The paper in the connectors bag says that this part is for rebuilt tranny with bigger cooling line holes but; according to my part guy, no other part # exist for the ally that I have.

Mike, Eric, anyone? Ever seen that?

I may need Mike's cooler just to get back to my "normal" temps if I'm stuck with that setup.

On another note, that "hot" TCM mode seems interesting at the drag strip! TC Lockup in 1st gear after take-off could give us a few 1/10s http://www.dieselplace.com/forum/smileys/HiHi.gif. My TC only locks up in late 2nd gear. Any toughts?

Life out of T/H sucks for me. Lotsa revs and not much progress. I typically select T/H whenever running hard, even just to pass someone.





Been discussing tighter converters, but I'm not sure if I want to kill the response...





Mike, I think a "strap on" thermostat would be a nice addition. That or sense in the cooler out line as this is "first hot".

My TC only locks up in late 2nd gear. Any toughts?


Normal in Tow Haul Mode.

Normal in O/D mode also.

I know that this is normal in T/H; I was just teased at the idea of the TC locking in 1st gear in that Allison "Hot Mode" for emergency cooling. Is there any way to provoke that mode for normal driving. I feel alot better when the TC is locked, at least the engine is reving for something useful: forward movement instead of heating up the tranny fluid.

Co-Pilot? http://www.dieselplace.com/forum/smileys/Embarrased.gif

I am thinking of building an after market transmission cooler, Maybe a double cooler set up on a headache rack that would be above the cab in order to get the most air flow.http://www.dieselplace.com/forum/smileys/Big Smile.gif


But with my luck, someone has already come up with this great idea.http://www.dieselplace.com/forum/smileys/Cry.gif

There are better ideas than what I am using. I have discussed my cooler with a lot of knowledgable people. We could put coolers anywhere you want and gain something. My goal was 20 deg drop. It must be drop in so that any of you guys can do it. No drilling, no cutting lines, no fabricating. I have achieved the technical part; Mr. Trippin will tell me if I succeeded on the most important part. His reports have been very good. When I switched coolers with him Sat; I had both Duramaxes running side by side checking for leaks. I grabbed the input cooler line to my cooler on his truck and could not hold it( very hot), I then grabbed the output line ( out of my cooler) and it was warm.http://www.dieselplace.com/forum/smileys/Big Smile.gif I did the same thing to Guys cooler which I installed on my truck, and both lines were very hot. It works.

Do you have a date yet that you will be making these for us. I mean saying this one works out the way you want it to? http://www.dieselplace.com/forum/smileys/Big Smile.gif

Pricing and ship dates please.

Mike, Give us an update on your new cooler you have been working on when you can

I am waiting on Mr. Trippin to get back from towing in the extreme heat of Arizona. I know some of you guys think Arizona heat is a *****.http://www.dieselplace.com/forum/smileys/HiHi.gif Before he left, I was getting regular reports of 20 deg cooler across the board. He is due back ant day now. I will get my report and either go into production or change the cooler. I am hopefull for a good report. I will have Guy report to you guys directly either way.

I can verify that! Just got back from a trip that took us through Death Valley mid day--outside temp was 118 around the dunes. We were pulling a 5500# TT with the truck bed lightly loaded as well. For those of you who know D.V. coming in from US395 on 190 and going to Las Vegas, you have to travel over 2 huge mountain ranges with 8% grades (I think they're steeper, but I think that's what was on the signs). Using tow/haul mode and I think the O/D was locked out but don't remember.

At one point, I was pulling uphill at about 65mph and about 3k on the tach with the air on--I was trying to see if I could even get the thing hot as I'd never been able to before. Well, the engine temp was pushing 225 and the trani temp was at least 2 marks above 200. At that point I decided to back off a bit, took the rpm down to around 2k and shut off the air. after a short bit the trani cooled off as well, down to around 200. Here in Las Vegas where temps routinely get into the 100's, in traffic my trani gets to about one mark above 200--I didn't know this was bad until now (damn! another expensive upgrage to the truck!)

The cooler is a go! http://www.dieselplace.com/forum/smileys/Clap.gif


Got the report from Guy Trip this morning and it was very good. 20 deg's cooler than stock across the board.


mike

My tow was with my tournament ski boat, family and gear. Approx. 6,000lbs in addition to my 7500lb truck. The power setting was the TTS 120. I set the cruise at approx. 5mph over the speed limit and let the truck have control. Minimum 60 mph... maximum 80 mph based on posted speed limit of 55mph-75mph. Starting in Los Angeles heading North up Interstate 15 through Vegas and on up to Highway 89 and on to lake Powell. Max outside temps were 114 degrees. My ATS trans with all the extra line pressure never went above 200 degrees max. A very consistent 20 degree drop over the stock cooler. While the engine temp remained constant at 205 degrees. I could take any hill at any speed and the EGTs remained below 1300 degrees.


Mike, could you make up another prototype? I don't think I'm going to let you have this one back. http://www.dieselplace.com/forum/smileys/HiHi.gif


Oh crap, you know where I live......and with the speed you installed this one at, I'd probably miss you doing the swap back to stock. http://www.dieselplace.com/forum/smileys/Cry.gifEdited by: Trippin

Questions





Ac on ?


What were previous temps on this run?


My tranny runs there, under 200 Stacked 120/Comp Juice level IV day in day out in 80 ish plus humid air.Just looking for a base line.





Mac

Mac - is youre running that temp loaded or unloaded ? I see that as well on reg basis here in Sac, drive up the road once warmed up and tranny is at 200 but im un-loaded in level 4 or 5 edge with the TTS stacked. In those conditions tested above pulling my toy hauler up and through the sierras i see just a tad over 200 on engine temp and 200+ on tranny. Im hoping for lower than 200 tranny temp on regular basis when pulling, and definitely 180's or less on reg basis running around

Outside temps were 102 degrees at my house when I left, and climbed to 114 as we went by the entrance to Death Valley, so yes the AC was set to 60 degrees. http://www.dieselplace.com/forum/smileys/Cool.gif Because the AC works so well in the 2003 trucks. http://www.dieselplace.com/forum/smileys/Cry.gif


A very consistent 20 degree drop in trans temps. for both towing at speed and stop and go situations where airflow is at a minimum.

Hey ya never know about the AC you may have been driving for fuel Econo but I've driven there and I couldn't really see you not running it. I'm aware it's hot AC full blast and yet the windows were still hot to touch.


My AC alone will make my IC Transmission gauge run at near 200 but not quite, while my sump temp runs 180 /185.


Problem is IMO the IC gauge isn't that accurate a measuring device do to the transmittal of residue heat transfer from the engine .The transmission sensor is in the top of the pan mounted to the Valvebody. So the entire mass would have to be cooler.Always going to run close to Engine temp in those kind of temps.

If we are looked upon as to aggressive others will be afraid to ask ,no?

I started this cooler project to help. Nobody else is or was interested. I decided to make sure it could be installed by your wife if necessary. (your dog might be questionable but not out of the question http://www.dieselplace.com/forum/smileys/HiHi.gif,some of you guys have dogs that are really smart). I made a deal with a cooler company to give me exclusive on my design. The cooler company is the best of the best. I was looking for a 20deg drop in temps, I saw it in my Duramax for the week I had it. Problem was, I don't do any heavy driving. Guy offered to help. I am pleased with his reports and have decided to go ahead with this project because I think it works. I am also happy that this is my cooler, my project, and I control it. Some people will have to steal it to get it.


mike

mike, i'm willing to pay. if you won't sale me one, i guess i'll have to make the three thousand mile drive and than i'll still yours.http://www.dieselplace.com/forum/smileys/HiHi.gif put me on your list. thanks buddy1

GUY, do you see any problems with the mounting or the core? Has Mike performed a line (psi) test? What are the main differences between the OEM and the unreleased cooler?... or can you really tell?





Burner---------- pre ban





I walked away from my truck for 5 minutes and Mike had the grille off. I came back 5 minutes later and he had the grille back on with the new cooler installed. Damn...this guys good!


Mike had made some prototype brackets that bolted right in and the fittings are the same as stock, so I guess the pressure test would yield the same results as a stock cooler install. Mike's cooler is certainly more impressive to look at than the stock one. Just looks plain beefier. I would have to say it looks "Dmaxian!" http://www.dieselplace.com/forum/smileys/HiHi.gif


So basically my involvement was that I happened to be in the right place at the right time and was getting ready to tow a boat in the heat for vacation, and I could read a gauge.


After that it's all Mike L. http://www.dieselplace.com/forum/smileys/Clap.gif

i know how to run one hot though, get her stuck in the mud and dont let off....ran mine up to 240 in about 4 minutes of tryin to get up muddy hill at the power line on the back side of the property...i made it up though

Mike,


When are you planning on ramping up on this cooler and/or brackets? Got a friend here chomping at the bit to get one of your new units. He wants to put it on soon....to make sure everything is good to go for when he pulls his 5-er to Arizona for the winter.


Thanks,


Wayne

Waiting on the official prototype with built in fittings. Then it goes to sheetmetal shop for final brackets ( they will be a little different).


mike

Mike


You say they will be a little different (brackets ?) will we have to do any mods to get them to fit, if so maybe a bend or 2?


Genohttp://www.dieselplace.com/forum/smileys/Hug.gif

geno


No mods whatsoever. The present prototype on Guys truck has custom made adapter fittings. I did not want the cooler company building a final cooler till I tested the unit. This cooler was chosen because it does not block hardly anymore airflow than stock. It is twice as thick. Stock cooler has 7 plates, mine has 23. Stock cooler is restictive when you blow into it ( hot or cold), mine blows right through. On a hot day, truck idling, you can't hold the inlet or outlet lines on stock cooler; you can hold the outlet line on my cooler comfortably ( inlet= passenger side, outlet= driver side). It's doing something good.

Has anyone talked to GM about warranty consideration? I should think there wouldn't be a problem, but ...Edited by: Ray403Dmax

IMO I can't see where this cooler would cause any warranty denial. It is much the same as the OEM with the only change being size and better cooling capacity. As far as I know Mike used the OEM lines and connectors so flow should not be a issue. It will in reality be better for the transmission. The techs would probably never know it was changed.

I don't know what GM would say, but I know that Allison told me that a larger cooler would not hurt in the slightest. You have to look really hard to see anything different on mine and it's huge compared to the OEM. It's black and just blends in with the rest of the stack.

What the hell----- Tell them it is a special cooler for the towing packages, 99% of them will say oooooooo I didn't know that and go on.


Genohttp://www.dieselplace.com/forum/smileys/Hug.gif

Geno


That is a good point sad but true that the dealers don't even know the products they sell.


Mac

It's usually when something fails, such as the A/C, when things get looked over a bit closer and then the fingers begin to point. Changing out a cooler still results in a system level change that should be tested at a system level and given the thumbs up. and I'm sure Mike L. and masterp2 will do their best.

My shop was a GM warranty station for 15 years, had 2 GM engineers spend 2 weeks inspecting and watching what we did. I still know people up there. I will present my cooler to them. I do not believe my cooler would ever become a warranty issue as I have been told to replace existing cooler on GM SRTA factory rebuilt units on HD trucks that I have installed. What will GM say when you tell them all their NASCAR racers use SETRAB ?

Sounds good!

I doubt that most guys in the shop would even notice that you put a different cooler on, unless it was shiny chrome or something way off base. I bet MIke's cooler wouldn't even be noticed unless there was a reason for the mechanic to look specifically at it. It's not like it's relocated with all kind of extra stuff, it's just what GM should have put on from the beginning. . .


If they do notice it, then Geno's ploy would probably work.


Dennis

How's things lookin Mike?

Update?

Mike,


Now that you rebuilt my Ally, (at 37200mi), I am ready to put in the cooler.


When, where, and how much.

If you would have let me get away with my 600.00 mistake, you could have had one for free. http://www.dieselplace.com/forum/smileys/HiHi.gif Now you will pay dearly.http://www.dieselplace.com/forum/smileys/HiHi.gif http://www.dieselplace.com/forum/smileys/Hug.gif. You know I'm kidding.http://www.dieselplace.com/forum/smileys/Big Smile.gif I expect first cooler tomorrow.

I am familiar with "quick change artists" and Mike did not get away with it.


Well maybe he did!!!


He rebuilt my ally and had it in in no time at all. I guess that qualifies as "quick change". And yes I did get my 6 bills credited. I locked him in the office until he had a receipt for me.


Thanks Mike.......http://www.dieselplace.com/forum/smileys/Hug.gif

Mike, So we are all waiting, what does the finished product look like, and what are the performance gains, how much $, and when... lastly, what is your stock on these...talk to us......thanks, Sir-Col http://www.dieselplace.com/forum/smileys/Big Smile.gif

What he said!

Second (or is that 3rd) that motion.

Im in.....when and how much?


Doug

Mike L.


Any updates? How are things going?

I will have a final date mid week. Going to order boxes Monday.


mike

Is there a cost on this yet, and (forgive the stupid question), will this work on all trucks regardles of model year and LB7 vs. LLY?

Very interested, anxious to hear what the price is going to be.

Marc

Should work on everything with 5/8 lines. 1/2 in lines will be addressed soon as fitting is made ( cooler is same). Should have price next week.


mike

Any new word yet? I am Jonesing for this cooler!!! http://www.dieselplace.com/forum/smileys/hihi.gif

I am so tired of saying soon, but it will be soon. I have the Setrab coolers in stock and just need a couple of tweeks. Remember, this will be drop in and that makes things a little tough. My name goes on this cooler and GOD help me if I make a mistake.
mike

Looking forward to the new cooler Mikehttp://www.dieselplace.com/forum/smileys/Rock On.gif

You have until the first week of Nov to have it ready, because that is when I will be at your shop on my way home from my cross country 5th wheel retirement trip.


So be warned, if I show up and you don't have one to put in, I may do the "hit" myself.


Looking forward to seeing ya in Nov.


Lyle

Has anyone done ANY estimation or calculations to determine what this mod will do to degrade the radiators cooling performance, or how much more fan clutch activation will occur, or how AC performance is affected? How about power loss due to a warmer intercooler and added fan clutch engagement?


Since this cooler will offload twice the heat of the old one, what are the consequences to the other 4 stack cooling system components? Is it possible if someone installs this in the winter, when temps are low, that come summer they will have an engine overheat issue under load (like many LLY's are experiencing now)?Edited by: masterp2

masterp2


Unlike your work on paper this cooler design has been run thought the summer heat while towing heavy loads, real world testing. Everything is working fine and have had very good results with no adverse effects. Having the ability to off load the heat over a larger area reduces the hots spots that can be caused by the OE cooler to the stack. It also slows the heating process for the same reason. Unlike your paper design it doesn't require cutting into the OE lines that will void the customers warranty or relying on additional fans to keep the cooler working properly. The overheating issues you talk about have not been present on the LB7 nor on the majority of the LLY's produced, so GM has a problem on some trucks. I'm sure with time they will figure out what is the root cause and supply a fix, it will just take them longer than most would like.

You can talk about my "paper design" all you want. I didn't bring it to the table, I'm not selling anything or discussing a design you know nothing about. My (actual) test data goes much further than 'hot to the touch' on an 80 degree day...


If you are the answering authority, I will assume the answers to my questions are all "no" except for the "no adverse affects" qualification. But with over 800 open cases of overheating LLY's with no solution except buyback, everyone should be asking the same questions.


As for the warranty issue, any mod to the cooling system will lay the potential to void warranty. The difference in court is that with the MM act in place, the dealer has to prove the mod was detrimental to the problem the dealer voided. That won't be hard to do based on what I see/know about this design.. For me I don't care what a dealer thinks, I can always bring a truck back in stock condition, i care about longevity and that usually means not playing the dealer game unless you know you will not own the thing after 36 MO. I'll still have mine then I hope.


Edited by: masterp2

I was curious what testing you had done so I poped back into your post and leme see if I can summarize what you noticed on your trip about your cooler design and moving it from in front of the stack.


14+ degreee drop in water temp with much less cycling of the fan


15-20* drop in trans temps


100 or so drop in EGT's


a few degrees drop in airconditioning output


That pretty much sumed up what you have found? I assume that anyone that utilizes your cooler will gain similar results?


I guess one can draw a parallel.....if removing the cooler does these things.....dumping twice the heat into the stack would have the opposite effects?


Mike Have you seen a 2 dergee increase in AC output?


Have you seen a 100* or so gain in EGT?


Have you seen a constant running fan and 235ish water temps?


Edited for horrable scpelinEdited by: ratlover

with mikes cooler it, if the worst were to happen and you need to take a truck back to the stealer, just
"unbolt" mikes cooler and put the stocker back in. how can they not warrenty something stock???? they dont need to know the whole truth. if you start cutting things how to you replace back to stock P ?????

My point is the cooler Mike is making has been tested during the Hot Summer months towing heavy loads, it's been tested in the shop and on the dyno too! These are all things you do before production if you care about your future customers. If you look at 800 known overheating LLY's Vs the 50,000 plus LLY's GM claims to have shipped it's a very small number and a simple transmission cooler is not going to fix those problems, that was never the design intent. The engines ran no hotter than before the cooler, the AC worked the same as before install and the fan appeared to be the same. I would love to say a data logger was installed to record the fan activity Vs air temp Vs load Vs ECT but it was not and I doubt if anyone else has done so. To say you dropped 2 deg in the AC is BS as most gauges are +- 5 deg on there accuracy and I'm sure you were in a controlled temperature room to make sure there were no outside variables influence the outcome, right. Mike's cooler dropped a solid 20+ degrees of transmission temperature which by the way is what he was looking for!

Diesel Tech

The first test you decided to do on my truck after cooler install should have smoked the trans but it did not. Blocked the wheels, put it in drive and brought it up to about 1800 rpms for 10 minutes. http://www.dieselplace.com/forum/smileys/smiley36.gif

mike &n bsp;

I'm not trying to ignore anyone, this is NOT the place to discuss anything I have done on my own, that is not respectful and I won't discuss it here. Mike L tramples all over my threads, and then his posts are deleted, he just has no decorum. Diesel Tech, you can rant all you want. Distract all you want. Accuse all you want.

There are still no answers to my questions, and that's fine. If I really thought it was a solution and not 3 problems, i would never have reinvented the wheel. I'd prefer a factory looking solution also, so I put the bigger cooler in the stack, then took it out the next week as it made other issues worse, intercooling suffered for one, my AC vent temps showed numerical losses, and these were all predicted by me before I measured the result to make my assumptions quantified... real.

It had been some months since this was asked, just thought it should be asked again, since there has been plenty of time to get those questions answered. I have learned a lot since then, and I believe in my heart there is reason for concern. Anyone seeking lower trans temps is going to value it most in the most extreme conditions, the same conditions that make AC suffer, intercooling suffer, engine cooling suffer, you can't hide from it. If we needed lower tran temps in the winter this would be perfect, an oversized cooler to help keep the engine warm. But it doesn't work that way. That's what is at issue, ranting wont disguise it. Also, it is not my job to prove anything. It's your job to make this believable. I have just pointed out the obvious. As i have said, I have no agenda here accept to ask the questions noone seems to be concerned with. It just absolutely surprises the hell out of me that I am the only one.


The open cases on overheating may be unrelated to stack innefficiencies and new heat surpluses, but to believe that is absolute ignorance. I believe they are the ones trying to do what GM said the truck could do (and heating everything, not just trannys). I have been wrong before. But I studied heat transfer, hydraulics and thermodynamics for 4 years. Very easy math here. If you want to cool the engine, AC, and IC better what do you use, hot or cold air? Good we agree, so why do you think putting more warm air (and less of it due to masking) to those tasks, will not have a deleterious effect? Beyond me.

It was a simple question. Still, no answer. Clarified.

masterp2 no ranting just some simple facts, this cooler design has been tested. The results are what Mike was looking for. What I am saying is 2 deg. could have been cause by to many variables and you know it, unless you were able to control them all, it's called test to test variability. With out having the proper test equipment it's nothing more than an educated guess and that's fine if that's what your looking to do. I answered your questions but you didn't like the answers so you have chosen to ignore the results, that my friend is your choice. http://www.dieselplace.com/forum/smileys/smiley5.gif

Unless provided for I think we could possibly be seeing some overcooled trannies this winter. Imagine a cooler that would maintain 165-175 degrees through the seasons, has no fans,unburdons the stack completely and can be returned to stock in about 15 minutes.


Through various tests over the last couple months I have to agree with Mike and others that stop and go driving is the real producer of the heat we see. Line out temps approaching 260 degrees is scarry. Towing 12K at normal highway speeds in 95 degree weather was no where close to this.

Imagine a cooler that would maintain 165-175 degrees through the seasons, has no fans,unburdons the stack completely and can be returned to stock in about 15 minutes.





did you do it?http://www.dieselplace.com/forum/smileys/smiley4.gif


I have no idea where 2 degrees came from, just as well. If you are going to criticize me, can't you at least quote me accurately?

3 months of data gathering and the fab work is complete. Install will be next week for the most important test of all. Of coarse I will be waiting for the seasons to come around but it looks very promising.


On edit I should say completing the install will be next week.http://www.dieselplace.com/forum/smileys/smiley4.gif Edited by: a bear

mr. p, is it possiable that the cooling system isnt at the max yet. lets say there is the "hot spots" you claim there could be, couldnt the stock system handle that just as well as not handle that????? so if the system isnt at max, the stock cooling system other than the cooler, could just keep on trucking. these trucks are kinda young, we are moving into a ground not yet known. anything is possiable. my .02 cents is, if these motors arent over heating then we have not pushed the right buttons yet, so there is more, please dont doubt mr. mike L, lets see what the masses say--they dont lie!!?

Are you building a cooler? Cool if you are. I have noticed that agressive stop and go driving will skyrocket Ally temps. I have also noted that incresed line pressure in the Ally will raise temps( Transgo converter flow valve) is a culprit here. Steve Younger at Transgo has been telling me that that valve is for race only and I believe him now. My cooler will bring the extra temps back down. As far as heating the stack; the hot spot in the stack is not in the center. Look back at some of the GM trucks and see where the auxillory electric fan was mounted ( Suburbans in particular as this was GMs premier tow vehichle) and this will tell you where the heat is in the stack, not the middle. Mesquito2 is trying to draw me into all his posts to pump me for info, even calling me a bigot. I like the fact that mesquito2 has kept my cooler post active and at the top.

Thanks Mike,


My truck has been running so good that I was dying to get under there and tear something up http://www.dieselplace.com/forum/smileys/hihi.gif The cooler set up I'm installing is simply a project I took on to keep me busy doing what I enjoy. No mass production here as this thing is simply not cost effective. I only went this route because of the sweet deals I made on the parts and plumbing. This $hit gets expensive. The cooler I decided to use is a setrab 272 that I made an excellant deal on. I am adding a 170 degree bypass thermostat due to the rather large size of the cooler 7.5 X 22" which will likely cause overcooling during the winter. I can really see the benefit of a cooler after running these temps at the various locations. As far as the cooling stack my ultimate goal is to stop or at least reduce that damn fan clutch cycling thats eating up my HP not to mention aggrivating the dog $hit out of me. If someone can come up with an answer to helping with that noisy fan clutch I'm all ears.

Hello Mike, Santa ask what I wanted for the holidays, :) .... Should I request a trans cooler.......or wait a while longer? Mrs. Claus does not ask often, nor does she wait too long, so a status report would be nice .........thanks

Sir-Col :)

Any news on this cooler yet?

Going to the sheetmetal shop monday with a baseball bat and a pack of gum. I don't chew gum.

Then what do you do with it?

It holds his a$$ cheeks togather.

Thats funny right there...I dont care who you are!

Hello Mike, Is the cooler going to be ready soon......did you have to use a bat.....? Please give us an update, many thanks
Sir-Col

I used the bat. He says I will have an answer friday.

Updates please.

-P.

Mike did not say which Monday !!! In fact he did not even mention the year....guess we all need to be patient a little longer

When I climb steep mountain roads with my truck, the kind with a lot of switchbacks and slowdown - accellerate - slow down... My tranny gets real hot. Would I benifit much from a larger cooler?

More than likely...I cannot wait for Mike's cooler to finally get into production!

Have patience........

I have it on very good authority that the bracket maker he was going to use flaked out and stuck it to him.

He now has someone on it that has a history of DELIVERY!!!!

I want one too, and I am willing to wait.

As it is said, "no wine before it's time", so is the cooler.

Nothing worse in the business world than to turn out a bad product.

Nick took his time producing his filter kit. It was worth the wait, and so will the cooler.

Patience is not my stronger suit, but if the cooler performs 1/2 as well as advertised I would still be happy.

Anticipation is making me wait!

Hello Mike,

How is the cooler comming along, a status report would be nice......a lot of us are now starting to anticipate our summer driving....and wondering if/when your cooler will be available....any pricing ideas yet....talk to us....;) Thanks.

Cannot help with pricing but I have seen coolers and fittings sitting at his shop read to go. I know he had trouble with the bracket supplier flaking out but the new guy is suppose to be good about getting it done. The cooler does work as advertised as I have a prototype on my truck. I've been running it for about 5 months without issue. Everything plugs in as it was stock.

TTT...just looking for an update if one is available! Thanks for your hard work on this Mike!

I am having a meeting monday morning with sheet metal man. This has been my last setback because it must be drop in. Sometimes guys I want to hide from you because it is taking so long. Setrab is very supportive and Steve Cole has helped design brackets. I will get her done soon. Bear with me please.
regards, mike

Hey Mike L. , how are we lookin' here? Any idea of an Eta would be nice. I need to start haulin' with the last 05 here shortly and I have done nothing so far with the aspect of cooling the allison. Truck is on the hoist and almost finished to go.I'll go our usual route again if I have to, but it requires fab.


Thanks. Tom L.

Can you dumb them down a little for me Mike?):h

Mike,

It's been a while and I don't remember if it's been posted already but do you know how much the new cooler should drop tranny temps compared to the factory unit, all things being equal ?

DD

We have seen a consistant 20 deg. drop and much faster cool downs.

I've had the prototype unit on my truck for about 5 months. I have not towed anything but have loaded the truck with about 2500 lbs and hauled things around. What I can tell you is everything heats up much slower than before and seems to settle in around 20 - 30 degrees cooler than before under the same conditions. Summer will be coming up soon enough to see how it works in the good old CA heat of the summer, but last summer we tested it on Trippin's truck while he took his family vacation towing his boat and stuff through the desert heat and he saw a 20 degree drop in his rig. Hope this information is what you were asking for.

Can you dumb them down a little for me Mike?):h

That might be a little difficult!!!! At least Mike will have a real challenge, :laugh_exp :rotflmao: ................I just kill me!!! :shootself

Thanks

I will be taking orders Monday. PM me if you would like one. I thank all you members for being patient with this project. I almost dropped this project several times because I could not get the support products that were needed to make this a true drop in cooler. Many thanks go to Steve Cole ( Diesel Tech ) for his hard work and design of the brackets and coming up with the fittings needed. He and I spent a lot of time fitting the cooler. I got real tired of him trashing bracket after bracket because they were not to his liking. He was right and it was worth it. Thanks also go to Guy ( Trippin ) for his input and his tech feedback and machine work. I could not have done this without these guys. You guys are going to like this cooler; it has 1 year of my soul in it. Thank you for the interest and support.
regards, mike

Congratulations Mike!

I'm sure we will soon be adding Mike's cooler to the hall of fame along side Finger's stick and Kroutman's plate...

:confused:

:confused:

Not sure why your confused. but I'll take a guess.
Mike didn't send me directions with the cooler. He thought you were going to come over to my casa and I would just copy how yours was installed. Turns out I didn't have to go that route. Super easy installl and NO fluid spilled.

OK! I get it now. Yes it is easy. Of course Mike makes rebuilding the Allison look easy so I had to take what he said with a little grain of salt since I have two left thumbs and no fingers sometimes when it comes to working on these trucks.

Mike,
I received my cooler last night. It was an easy install thanks to the design and instructions. It took about 45 minutes to install. All went well. My Tranny and I thank you.

Mike,

I got mine today...installed in less than an hour (pushbar issues kept me from removing the grill without extra effort...should have done that in the FIRST place!). No leaks and great fit/finish! Well worth the wait! I will let you know how it works on my cross country trip to NY in the middle of July!

I cannot say thanks enough!!

I have just returned from a mini torture test across the Rockies. I went empty from Denver to Grand Junction. 94-98 degrees climbing the eastern slope. Tranny never registered more than 170 on the OEM gauge, while under similar conditions I have seen 210+.

On the way home pulling U-Haul's version of a car hauler, more akin to a boat anchor (the trailer alone weighs 2,000 lbs), and a Honda Prelude weighing in at nearly 3,000 lbs. This is the first time my dually has dragged anything big across the Great Divide, and I was very much looking forward to it!

On the way home I discovered a few things:


GM Duramax :ro)
The Temp Never rose above 190 :ro) Even with ambient temps well in the 90's
There are alot of nice people on the roads! :ro)
But there are more morons! :rolleyes:
Dragging 5K on the bumper is like running empty, except running downhill!
Tow/Haul :ro) for grade braking!
But running 1K over redline while in Tow Haul was scary!
Mile L's Transmission Cooler is HIGHLY recommended! Get yours today!


PS one more thing: Loaded, uphill I smoked what appeared to be an 01-02 Stepside Extracab. And a Minivan piloted by a soccer mom from a standstill at a stoplight.

GOD I love my truck!

Operating in the red zone while in grade braking is not a problem, the engine is designed to do that. Check out page two of the link below for details:

I am aware of that, thanks...hearing your Duramax scream @ 4K rpm has a little unsetteling effect.

The Duramax does have some very good brakes that will keep you out of the red zone. Later! Frank

Actually, if the fan is not engaged, the engine just purrrrrrrrssssss at 4K.

Love it
