I will be getting my trans. done in the next couple of weeks. I have heard that the '01's take forever to learn on their own. Will a tuner like the quad, be sufficient to set the TCM for fast learn, or is a Tech2 the only thing worth using on the '01s?

The reason I ask is that someone with a quad tuner would be much easier to find than someone with a tech2.

SnapOn scanner will work on the '01.

??? I thought I posted in this? Wered it go?

Anywho. You going to indy? I will be and could bring my snapon scanner and I'm sure you could track down someone there with a tech 2.

I looked at moss's trans with my scanner after he used the quad to rest things and it did apear to do at least a partial. my scanner dosnt show everything though. He said when I used my scanner it shifted different at first than the quad did IIRC??? Who knows???

Mike correct me if I'm wrong but i believe the fast learn proceedure is not available on the 01. The 02's were not even avilable with fast learn till mid year and only after a TCM software update. The Tech2 will only reset trans adapts on the 01.It will not fast learn. Tim

The adaptive strategys on the '01 are not like the '03 and later. TAPS must be set on these early models because they learn so slow ( good thing IMHO) Later models like '03 and later do not need the TAPS set in most cases because the TCM will adapt much faster no matter what you do. The older TCMs need a kick start or they may need over 100 ignition cycles to begin to learn. If there was a major failure in the Ally, then the TAPS must be set no matter what year because the TCM is locked in the high pressure mode and needs to be told that the failure is corrected. I had to reset the TAPS on Chads truck after the trans failure. That is pretty rare on a late model. Hope this helps. I can make the SnapOn work on the early models.

I guess I'm not talking about the addaptive process while driving as much as the scan tool fast learn.The output test where it learns clutch pack clearance and apply times as a base starting place for the road test adaptive learn.This process of quick learn is not available till 02 and only with the newest software from GM. Tim

Fast Learn is when you narrowed the clutch drum volume parameters ( timing a shift by how long it takes). The TCM is always looking for that perfect shift ( programed) and will bounce from the high pressure side to the low pressure side while looking to adjust the timing. The early models are not as fast as the '03 and later models in doing this, but they all do it. Sometimes they don't respond at all ( early models).

Hang onto your Hat and don't bring drinking fluids for the ride!

Philip, I'm planning on going to Indy(at least for one day, my brother is getting married:rolleyes: ), esp. if I can get my trans. done before then. I'll be able to tell you for sure early next week. Gonna call about a trans. appt. later this afternoon. Thanks for the help.

Mike, are you planning on making the long trip to the Hoosier State?

Mike, are you planning on making the long trip to the Hoosier State?

Wish I could make it but I have too much work to do. :(

I wonder why your so busy? Everyone seems to think you know a little about trannys or somethin.:confuzeld What's that about?):h Its a shame you can't make it.:(

Mike will your Snap On scanner do the service bay addapive learn in output cycling on an 01. The service bay addapive learn is only avialable 02-05 with the tech 2 or allison doc software? Do you have the Modis scantool. That might be worth investing if it can do the service bay allison tests. I need to invest in another tech2 anyway maybe that would be a good choice Thanks

OT but were at in IL are you?

I have an 01 cartrage in mine but lie to it and tell it my 03 is an 01. It lists the garage taps in there as being able to be done but it dosnt seem to do anything :confuzeld at least not like all the clanging and banging a tech 2 makes it do

midwest
The SnapOn Modis will not help you. I have found the Allison doc program to be the best. I do not have one but borrow Transgo's when I need it.

The clanging and banging is the service bay test/learn I am refering to. Just reseting garage shift, and other shift adapts is not the fast learn. It is doing just as it describes, restting the adapive process to a base level.The addaptive process will take several upshifts and downshifts to learn without the service bay addaptive learn. With the fast learn it is pretty close in 4-5 steady throttle upshifts.It allways seems to be learning though. The 01 can not be fast learned in the service bay with the tech2. Tim

What is it you are looking for? You seem to know more than I do, so why are you asking questions? Buy the Tech 2 and fix your problem. Problem solved.:D

The first post by Slick was how to fast learn an 01 allison. I stated that I didn't believe the FAST learn was available on the 01. The taps may be reset but the service bay output test Fast learn does not work on a 01 with the tech2.
Mike you stated you use the snap on to do this and I assumed it did something the tech2 does not. I do not use the snap on scanner and if it does this output it would be very useful. I do need another scan tool as someone allways has my tech2 and I wanted your professional input and not just yanking your chain.
I guess i was not shure we were on the same page thats why I kept replying.My understanding is that all allisons have adaptive learn but the 02-05 have the ability to be FAST LEARNED.That was my statement.
I wasn't trying to cause problems.

I prefer to do the Allison Fast Learn with the Tech 2 at install time. This is what Midwest is referring to and Slick's initial post brought forth the terminology indicating that this is what he wanted to do.

I just want my trans. to learn the fastest way possible. Just don't want to have to go through a week of relearning.-:t But if that's what I have to do, I will.:)
