Ever since i switched to the Amsoil tranny fluid my tranny has started to limp when on the turnpike....sucks i really hate this stuff, anyone else have this happen? Before the truck always ran tough and tranny shifted really strong, now the damn thing slips....sucks....so mad.....anyway

-Ltrain

That sucks! Try some Mobil 1 Synthetic, it's worked great for me.:D

Which Amsoil ATF version are you using?

i think its just a coincidence. mine limped and slipped in the 40 hp setting while pulling. and i limped after that in 65 hp setting not pulling. remember after it limps once it is much easier to limp after that.

I don't think it's the Amsoil. I've tried a number of things with stock clutches and Sun Coast clutches using Amsoil ATF.

:ro) OK, this post has been up for over 36 hrs. and you have been asked several questions. I'll re-ask plus ask a bit more. Maybe you can do us the courtesy of answering as we all try to learn from each other's experiences.

Are you using the Amsoil Univ. ATF or the Amsoil Torque Drive? Mileage on truck? Stock or modified? Pulling or not, and if yes, how much?
If you are going to throw in a post maligning a product, then at least answer questions and provide details. Otherwise, IMO, the post and attendant accusations are meaningless.

I swapped out my OEM ATF with Amsoil 3000 synthetic ATF at 36,360 miles. I just replaced that charge of fluid with a fresh one at 92,327 miles. With 96,000 miles on the truck today, that makes 60,000 miles on the Amsoil ATF with absolutely no problems. I have an Edge with Attitude, I do run mostly in level 3 with occasional level 4 and level 2 when towing, always defuel on 4/5 shift. I do not race or thrash. I was surprised how fresh, clean and clear my fluid looked when I dropped the pan for the change. Am I slipping, or didn't this original post have a Predator 120 and a 14-something 1/4 mile time in the signature? I remember thinking that a 120 horse box and dragrace times seem to indicate that it's not the fault of the fluid if the tranny is slipping!

Didn't Sdaver post that the same thing happened to him long time ago? Maybe he will chime in.
mike

Daver felt diminished holding capacity (pre Suncoast upgrades) when the Amsoil Dex III was installed. Holding improved when the Transynd was reinstalled.

Now if we could get an answer as to which fluid...

I discovered this about 2 years ago..............too slippery.............I used the original not the new one developed for the allison ..........flush it switch back to dex 3 or transsend.................took 2 flushes for mine to improve........hopefully your c3s are not glazed to bad

It has now been 52 hrs since Ltrain first posted his attack on Amsoil atf. Nine people have replied wirh questions or comments, still no response to questions and comments. I've got to believe we have a troll here.
I will admit to being an Amsoil dealer, and a believer in their products, WHEN USED AS INTENDED. I don't appreciate attacks not backed up with facts, whether or not I have an axe to grind!
SDaver has extensive modifications, and probably he was able to slip the trans with Amsoil in it, but was that huge increase in power the intended use of Amsoil ATF? Idle Chatter has a more reasonable tune on his truck, and has had good success with the Amsoil ATF, including towing.
Ltrain, are you out there? Speak up!
I've been driving motor vehicles for over 50 years. And I've turned wrenches on them the whole time to try to keep them running. I've learned a lot in that time, but I think one of the most important things:
"You can put some people in a padded cell with a steel anvil and a rubber hammer, and they'll teat them both up."

Amsoil in my tranny for 375,000 miles 70% towing Rv's for delivery. NEVER the first problem with the tranny!!!

Dear Dirty Old Man,

Maybe he sent the post from a computer at work and now he is off for the weekend. Not everyone camps out on the computer.

I thought this was a forum to ask questions on. Before you sell him out because he questioned your oil, step away from the coffee and give him a break.

It's just a question.

By the way, I'm timing you to see how long it takes you to reply.:)

OK Romark, here I am, you can click your stopwatch! Yes, this is a place to ask questions, make comments, and learn from each other. But you don't learn very much from people who don't tell the whole story and won't answer questions. Ltrain made his first post on this subjest on i/18/05.
My calendar says that the 18th was last Tuesday. If he is using a computer at work and hasn't been at work since then he has a better job than any that I ever had before I retired! Several people have asked questions since then that have gone unanswered, such as ; (1) were you using Univ ATF or Torque Drive? (2)are you towing, and if yes, how much? (3) what is mileage on truck? (4) is truck stock or modified? (5) etc.
All of this has gone unanswered, so I took the trouble to go back and look at his previous posts and find that his truck is modified: Predator on 120 hp, exhaust mods, and whatever else it takes to get a 7400 lb truck thru the quarter mile in 14.82! Now if this won't put the hurt on a stock trans, I don't know what will! In one of his posts previously, he comments that a 120 hp setting on a Predator WILL LIMP THE TRANS.
So, it appears we haven't been told the whole story. Just wants to blame the fact that if you wanta play, you gotta play, on Amsoil. Then disappear when he is questioned about it. Sort of a hit and run it seems.
Yeah, we all learn by sharing our triumphs and trials, but not if we don't tell the whole story.
Now click that stopwatch again and see if you can come back with another snide wisecrack. Or maybe Ltrain can do it for you!

Dirty old man,

Sorry it has taken me 11.75 hours to reply but I had to go home and get some sleep. I am not priveledged enough to be retired. By my best calculations I still have to work another 20 years.:( But I am saving as much as I can so I can make it happen.

You seam to have done your homework about the origional post. It seams to me that those who modify their trucks are having the most problems with reliability.

That is why I believe I will leave mine stock.

I didn't mean to put you on the defence but I thought we all were on the same side here.

Now I certinaly hear what you are saying about those who modify their trucks then camplain about problems.

As far as my "snide" comments go, just calling 'em as I see 'em. Just like you. No offense intended. Hope this smoothes your feathers out a bit.

Want to hear somthing that will really get you going... I have Royal Purple in my truck!!! Ha ha Ha!!! Hope you got a laugh out of that one. I did.

So hear it goes... "Click" That was the sound of my stopwatch!!

By the way, If you don't see a reply from me after tonight for a few days, don't fret, I'm on my days off and I probably will stay away from the computer. But I will be here till 5:00 Am Central Monday.

So there it is. Give me your best shot. I look foreward to hearing from you.

Regards,


Mark

Lightened up Old Man before you have a cardiac. He will be back. Later! Frank

OK Mark, now that you understand that my main concern here is that Ltrain seems to doing a sort of hit and run by jumping in and blaming Amsoil atf for limping his trans, when it may be and probably is the fact that his engine is extensively modded and is stressing the Allison beyond it's torque capacity unless it is beefed up to handle all that torque, maybe you understand my consternation.:) I just don't like to see someone blame ANY product for problems that are their own fault. Especially to make the accusation, then disappear with no response to questions and comments.

I agree with you about keeping my truck stock, as I learned a long time ago to keep your daily driver pretty much stock so that no one component is overstressed because of the mods to another part. The Dmax has all the power I need to pull my TT as it came from Chev. and I don't have to worry about my warranty being endangered by an over zealous service manager.
If I want speed , I have a Lincoln MK8 that is pretty fast, and I'm building a street rod also, which is where my go-fast money is going!:D

Royal Purple? Hey, at least you agree that there is a difference in oils and you are willing to pay a bit more for a better oil! Royal Purple makes good oil, as does Mobil 1, I just happen to believe Amsoil makes a better one!

Please allow me to apologize for the crack about snide remarks. I just found your post yesterday morning before I had my first cup!:rolleyes:

Seeing that you sell Amsoil and being somewhat of a lubrication enthusiest myself I am wondering what it is that leads you to believe Amsoil produces a better product than Mobil or the others. :confused:

Dirty Old Man

So I was right about the coffee!! ):h

Glad to see we both have a sense of humor.

You bring up an interesting point. I know that everyone says that synthetics are better but do you think there is that much of a difference to pay the difference?

I know that most have a biased opinion, however I think the truck would probably fall apart around the engine and trans. before I wear it out with dino. fluids.

I know numerous people who put way more miles on their cars and trucks on dino. than I ever will.

There is an interesting demonstration on the Royal Purple web site where they do a comparison with a Harley and a hot rod camaro with RP and dino. They use some sort of infra red camera to show that RP runs cooler than dino.

That is why I went to synthetics but I sometimes think I am wasting my hard earned money.

You seam to be more educated than I on these matters. What input can you give me.

Thanks for your information.

By the way, how does the price of Amsoil campare to Royal Purple. I don't even know where I can go to buy Amsoil around here.


Have a good one and please don't forget your coffee in the AM.:p

Now as far as you telling me that you are retired? Now you are bragging to us working folk. All my retired friends (which I have quiet a few) always encourage me to go to work. They want me to keep paying their Social Security.:D


Mark

Amsoil Universal in a stock setup and use the Torque Drive for modified trucks. have had the Amsoil Universal in my stock LLY for about 20K miles and no problems. But I will chage it over to Torque Drive be I load the Preditor.
Greg

Mark: Idon't know how to compare Royal Purple prices with those of Amsoil because I don't know of a local outlet for RP! Are they (RP) marketed thru any particular chain such as NAPA or O'Reilly's? Or are they sold thru independent dealers like Amsoil?

Many folks don't like the fact that Amsoil is marketed thru a multi-level structure. However, I regard it as Col. Amatuzzio (the founder) being true to the roots of the original dealers that helped him get the company off the ground in the early 70's. Sort of like dancing with the one you came with!

A Bear: Yes, I recognize from many of your previous posts that you are knowledgeable in the field of lubrication. And I sure as hell ain't going to knock Mobil 1, or RP, both are good products.
But, I believe Amsoil carries a broader, more user specific line of lubes and oils, all in synthetics, than most. I don't want to jump in and advertise my business here when Greg is a paying sponsor here and sells Amsoil, but if you'll PM me or email at cpropman@bellsouth.net with your US Mail address, I'll mail you a catalog from Amsoil. Greg, please don't get pissed, just trying to convert a couple folks to our side!
I don't have much to compare Amsoil to Mobil 1 in the atf field, but as far as motor oil goes, I have the results of 4-ball tests that show a smaller wear scar with Amsoil compared with Mobil 1.
Hope I have shed some light on this subject with this novel!:)

Dirty Old Man. I do agree with you and your point about the "hit and run". I too am an Amsoil dealer and do not like the fact that people balme a product to be at fault for what they may have done.
I have been running the Amsoil ATF in my truck since about 25k. About 10K ago I did change over to the TorqueDrive. I have since added the Predator and have run it on all power levels including the 120 hp level (I did not really push it on the 120). I have never had my transmission go into limp mode nor have I ever felt any decitable slip. I do not tow often, but I have towed some pretty good loads and never had a problem with the Amsoil.
As far as other synthetics go I am on the same page as you there also.
I once looked into Royal Purple to see about getting a dealership and as far as I can remember they only sell to stores and such and I think that there was a minium order buy-in as well, but not 100% as it was a long time ago.

Kevin

dirty old man, Thanks for the reply. I plan on switching to a syn ATF after the Ally upgrade in March. I never heard of the Torque Drive ATF but just started attempting to seek out which product to use. Is this ATF a new Amsoil product? I'm kinda staying clear of the Transynd due to the discoloring issues. And Royal Purple, well thats another story. Can't say for sure that what they offer today is the same but a past experience caused me to stay with dino for years. In a future second attempt I'm thinking the syn would be good in the tranny for severe duty along with enhanced cold flow properties for my now modded ATF cooler setup which substantially cools the fluid pre radiator.

Tommy
The Torque Drive has been out for awhile now. All Amsoil did was reverse engineer it. This will hold all the power you can put to the ground. IIRC Nick is running it in his Dmax as well as many others here and on TDP.

As for the discoloring that is a non issue IMHO because its just die. GM put it out in a bulletin years ago that it had die in it so it would not get mixed up with motor oil on the assembly line, and that color meant nothing. I know that VW ATF is almost clear.

Greg

I ran amsoil atf in 1999 6.0 gasser for 230,000miles and counting. Have 40000miles on 04.5 allison with torque drive. I have had every opportunity to limp mine but am fortunate. I have edge, propane, afe intake and mbrp no cat exhaust and get poor mileage due to the lead in my foot. mostly level 2 when towing.
my 03 cents

Nick is running Havoline Dex 3. This is what I put in his truck a year ago Dec. '03. I would say he had good service out of it and this is the same fluid I put back into it. This is the fluid all my customers get, and it is the fluid I have in my recently modifyd test trans. Any of the big name oil companys make good fluid. I myself prefer Mobil 1 but will not waste the money while I am testing.

There can be a problem with certain fluids causing limp because they were not adjusted to the friction coeficient of the clutch lining. I have found ( and so has Transgo) that if the fluid is not adjusted to your clutch lining, you can lose up to 30% holding power. That will cause a limp. I believe that is why Amsoil ( yes I was a dealer) changed their fluid. Just adding the wrong trans addative will change holding power for the worse. How do we know if we added the wrong addative or used the wrong fluid? I don't know. I do know that a good Dex 3 works well, and Mobil 1 is a direct replacement for Dex 3, only synthetic. I am changing my mind about TranSynd because of what Raybestos has found in their test. I am learning every day.
mike

Thanks Mike.

Greg, The color change I was refering to was the Transynd (Castrol) Aparently there has been cases reported where it has turned to a burnt color after time in the trans. I think associated with heavy use but not sure. GM has wrote it off as the nature of the fluid but IMHO that can't be good.

I have only heard good things about Amsoil, but I run what the GM mechanic sales me. No problems at all, and lovin it.

wickll

The tests Raybestos ran on the TranSynd was on their brand of clutches and no one elses. They found that it gave their clutches a bit more holding power over the Dex 3. They did not test Mobil 1 or other synthetic fluids. Now, could the same thing be said for factory B/W clutches? We don't know. We also don't know if Mobil 1, Amsoil or any other synthetic fluid would would match or surpass it, or be inferior to it. I do know that the ball bearing test is nothing but a scam.

Years ago myself and a few others bought into a hyped up ball bearing scar/amp draw demonstration that afterwards turned out to be a costly lesson for my company and myself personnaly as I had also tried their oil in my personal truck.

Tommy
I can pour pure bleach on a ball bearing and keep it from siezing in the ball bearing test. People need to stick with a major oil company for their own protection and their vehichles. I have access to trans lubricants and addatives available only to professionals and have found all of them lacking. If the oil or fluid you are using doesn't do the job intended, don't use an addative, change the brand of oil or fluid you are using. There is some good $hit out there that needs no addative.
