Hi all. It's been a pleasure looking through the forum for the past 8 hours! Yes, 8 hours. I'm new to the forum and am a fairly new Duramax owner. I've had my Duramax for a year next month. Here resently I purchased the Edge Juice Attitude combo. I found it on ebay for $425.00. The only thing I can say is wow! It does have the 125 HP setting on it and it is unbelievable comparted to stock. I've only had it there a few times. I've run it pretty hard and the Tranny has never gone into limp mode. I've heard from many people that running in this mode (empty) will eventually fry the Allison. How much truth is there to this? How much can a stock Allison actually take?


Any help here would be greatly appreciated.


Thanks.

You can and will do damage no doubt about it in level 5.

Most have said (agreed?) that anything over 90 additional HP will start to take it's toll on the Allison pretty quickly. Level 5 on a Juice with Attitude is definetly above 90 HP. Before I upgraded my tranny, I rarely ran my Hot Attitude Juice in level 5, mostly ran in level 3 (which is 90 HP). When looking at the clutch packs while out, they were slightly burned. Never limped it though.

I never limped my trans or zinged it. ran level 4 for a long time and ran level 5 for 2 weeks(once I had the suncoast stuff sitting there ready to go in) and I had some slight burnage to the clutches. I have a realitvily lite truck too and smallish tires(265's).


Ever notice how the truck seems to pull about as hard in 5th gear with it set to 90 as it set to 125? Thats becasue the juice is backing down power becasue it is sensing some slipage. Or go line em up with a truck with a modded trans and you both running a juice on 125, I did and man was it an eye opener, once we hit 5th it was like I was tied to a tree. just my expereince. you may be fine at 125 but you are really playing with fire IMO

Predator, 120 tune, Doesn't back off like the Juice, lasted 5k before it limped my Alli. Now I just run the 85(90?) tune, (for now).

Thanks guys for all of the replies. It's always good to get the facts from one who has experience. Sounds to me that I will need to start saving some money for that Suncoast. I will be sure to watch what I do. Like I said before, I've only had it in that mode 2 or 3 times. I usually leave it at the 90 HP setting for normal driving. It seems to get the best gas mileage there when you drive "responsibly"!


So which Suncoast should I go with? I have no intention of doing anything more than running the Edge. I won't be stacking, NO2, propane or any other mods. I am mostly out for good drivability and usitility.


Thanks again for the help!

We have all said thathttp://www.dieselplace.com/forum/smileys/smiley2.gif Its like a drug i tell ya, soon you''l be looking for a bigger fixhttp://www.dieselplace.com/forum/smileys/hihi.gif


How happy are you with it in the 90 hp level? If your totaly happy just leave her alone. A transgo kit with a new converter is the cheapest wroute and will hold a good amount of power and if you do it before you hurt your truck you may get buy without having to buy clutch packs. A single disk and a transgo kit and a hot juice would have plenty of nuts and live I believe. But clutches are cheap......smoke em if you got em and give Mike a call, he's got the parts and the knowledge to fix your F upshttp://www.dieselplace.com/forum/smileys/hihi.gif

What is a limp verses the zing of the tranny? I recently while in level #5 with the Edge juice had the tranny drop out of fifth to fourth. It wouldn't shift to fifth until I stopped with the engine off for about five minutes. The check engine light stayed on for about a day. Have others experienced the same.

First the zing ( slipping clutch pack), then the FU light on the dash, then the Limp( stuck in gear).

Just to add to what Mike posted,


Limp mode is fail safe for the Allison. There are many reason why a Allison can limp but we are talking Performance mods here. A slipping clutch to a differance in Input/Output sensor speeds.


In limp There will be only one forward gear third,no reverse and will illuminate the SES light as codes will be stored in the TCM.


Zing is what we found out will happen once clutches applied in OD get worn enough they slip and your tranny feels like it's in neutral when accelerating in OD.


Many of us have experienced this waiting for tranny upgrades and were quite good at catching the slip before it would limp the transmission.


We referred to this as Zinging,goofy but effective.

ive had mine go to fourth gear only and was able to reset with shutting vehicle down for 5 minutes. 0700 was the code. shop said occasionaly it will limp like this when the slippage isn't to severe. only will get worse if you continue to use the same power level.

bigbird

The 700 code is a comand for the SES light, you had another code or more. Anytime you limp the Ally you did some damage to the clutches and that is severe slipping.

mike

I guess what I experienced was the limp mode. Yet I recall reading that with the Edge program it would monitor clutch slippage and detune before causing limping. Was I wrong or is it just not able to react in time while on power level 5.


I learned my lesson and won't be harming it at the Extreme level any more. Or have I?


Also I understood that stock alli can handle up to 900 lbs torque in 1st thru 4th with no problem. Yet I've read others have limped there tranny in these gears as well. Is this not the case.

stock ally will not like 900 lbs of torque at all.. Your way past slippage then. Stock converter is good to about 700 ft lbs is all, and thats a fresh one.


Save your coin for an upgrade and always go farther then you intend on needing. Then when the bug sinks its teeth, your trans is ready. The cost difference is smaller then you think from a basic upgrade to a thorough upgrade.

Listen to Eric. I think we all started with our mild mannered thinking about what we were and were not going to do with the Duramax. Most of us lied to ourselves and went hardcore (lots of power for no good reason). Overbuild it and you will never worry when you seek that extra horsepower. Never say never.

Eric/Mike,


What's the cost difference between Level 3 and Level 5? Is there much gain in holding power?


Also I was planning on doing the Level 3 myself. If I decide on level 5 would there be any machining or such that would require a trans shop w/ special tools to complete the install? Edited by: a bear

I'm pretty sure the stage V just comes as a complete
transmission. Looks like about 1500 difference in price, but you
still have to buy the converter, plus if you get the V instead of the
III there isn't any install headache:
