Found this link (http://www.allisontransmission.com/service/faq/index.jsp?CategoryID=11#95) today while looking for something else. Interesting about the ATF. Any mineral or synthetic can be used as long as its got the Dextron III spec.

This is the biggest BS sales pitch from Allison I have ever seen. It was written by some one that had no idea what is going on. This person has never seen any transmission. I invite Allison to come here and answer these same questions with a live knowledgable person sitting across the table in front of 6 thousand members. I am here and ready. Allison, how about you?


mike

That reminds me of a joke.





She's so ugly you can see the the bruises from where she was touched with a ten foot pole!

They like to knock the aftermarket, yet they have not learned to stack clutches correctly at the factory. thats just one of the things we could discuss


mike

10' pole in hand!


What "we" and the aftermarket is doing is "not" what Allison is interested in.


I have first hand knowledge of Allison testing a Aftermarket valvebody that was released didn't do what it was suppose to then revamped and released.


Allison builds more trannys that are in service trucks including fire trucks to garbage trucks,GM pickups to on and on. Mike show me failed trannys with documentation that it has failed do to a Clutch "stack" problem.As released form the trained professional in the factory.Used in it's proper application.


Everything on the FAQ is valued info for a Allison owner.


You are criticizing apples to oranges comparison of Allison design.Would you expect Allison to get behind a upgrade and warranty issues?


Then if so you will expect GM to warranty your engine now that in your opinion runs better with a TTS tune.


Not gonna happen.

Looking for failures? Look no further than this board. Transgo is taking alot of tech calls from Ally dealers that keep losing C3's in their in house builds. I have seen burnt clutches on the Allys in my shop and some have never been modded or pushed hard. Allison dealers in LosAngeles are installing bigger coolers on tow trucks like crazy.( I am speaking only for the !000, and 2000 series now) By the way, the Ally dealers around here are now stacking clutches properly.


mike

I have not heard of one UN MODDED stock Allison going down with burnt clutches in all 4 years of GM LD truck use


You'll have to point them out ,if possible.

stop in, I have some show and tell for ya

Mike L,


After reading every single Q&A on the page Allison provided, I do not understand your response? You seem to be getting all worked up over nothing. Allison has provided info in regards to servicing and use of there transmission. I personally learned a few things.


1. They like transid.


2. They reccomed keeping your filter magnet, changing the spin and fluid at the sametime and only changing the internal filter in a rebuild situation.


3. They have tested somebodys aftermarket valve body, and it did no good. Might have been the 100.00 dollar bully dog?


4. They have tested aftermarket exaust brakes and do not reccomend the type that do not communicate with the TCM.


5. They personally do not like 285 or larger tires.


6. They prefer aftermarket power modules that communicate with the TCM and limit power at shifts.


Along with the few items I have mentioned they also give great explanation of the grade breaking limits and capabilitys. They also go into overdrive funtions.


There are a few tidbits in this info., that could really help the aftermarket comunity and aftermarket design engineers/manufactures.


Mike L, what's the big deal?

stop in, I have some show and tell for ya

Eric if I brought my slipping tranny and warranty repair to your service department or any service department across the USA what would you expect to hear besides I dunno what happened just wont go ? http://www.dieselplace.com/forum/smileys/HiHi.gif

All I'm saying if used with in the manufactures recommendation the Allison transmission engineered by Allison is a world leading slush box. I am not saying that it cannot be improved upon at all to be used accordingly, as we are. I'm also saying there can be "some" failures do to mechanical or assembly, we are human. The implication said here looks different.
To say Allison doesn't know how to stack clutches is to say they never looked at a hydraulic flow schematic. Allison has been building trannys for awhile ,guess their doing it on purpose.
The Allison home page which is what the topic is about isn't a hotrod shop. To say they do not know their transmission is ridiculous and bizarre IMO. I mean really.

You and I will never see eye to eye. I will not post anything in any subject when I see your name and if you post in any subject that I am involved in, I will drop out on the spot. If that doesn't work, I will leave this board.

I think that this "aftermarket valve body" was one of the original units from the trans shop at upper elevations as I heard rumors of that. This was a VERY early piece from back before "stages" or "levels" even existed.

Even though the allison is great for its intended purpose.....you think Allison is going to go on the record and say


Gee, if we woulda drilled 2 orfices a bit bigger and changed a few springs and valves we coulda made the trany hold quite a bit more. I mean it probably woulda cost us 1.50$ more in parts. Even though the allison works fine for its intended purpose and dosnt need to hold any more some other group figured out how to make what we did work better, call em up and they will sell you one for 250$. Most of that cost is to recover thier R&R witch if we woulda built it like this from the factory it wouldnt have cost you anymore. Thanks for your interest in the ultimate LD transmission that you could easily make better with a drill and some comon hand tools in your garage though. And BTW the stock converter kinda sucks too


Its like all the fram comercials that show em against thier worst competitor
