95 AWD auto transmission problems

[abaum565]

Just picked up a 95 awd auto talon. It would shift very very hard from 2-3, no reverse no OD.

I pulled the motor and tranny before I could pull the tcu codes. But the pulse generators and shift solenoids ohm within spec. The TCU doesn't look burnt and there are no leaky caps and no bad smells.

So I found another auto transmission for a good price but I am not sure it will work (I have always owned manuals so bare with me). I have read that you can only use 95-96 auto tranny's with the 95-96 transfer case, and I would need the tranny and matching transfer case from a 97-99 to use that. Now today I was just told differently, that any 95-99 tranny will work. Could someone enlighten me.

Also, the other tranny I found is a awd turbo tranny but the guy wasn't sure what year. How can you tell the year from the numbers on the case? Here are those numbers:

W4A33K1UP02
DE3172

Anyone have a good way of testing the ecu out of the car?

Anyone have any ideas what could be wrong?

Fluid looked good and it was full also.

It isn't terribly likely that the tcu went bad and the symptoms don't suggest it either.

Reverse is entirely mechanical, the only time that reverse should be affected by the tcu is if the tcu is deciding to run the pressure control solenoid and relieving pressure from the transmission unnecessarily. OD is probably related to end clutches.

Has someone been inside the transmission? Sometimes no reverse comes from someone trying to do work on the transmission and failing to line the center support up correctly when reassembling.

I know that 2ga/2gb manual transmission are different and require a matching transfer case (but no changes in the rear end) but I can't tell you for sure about automatics. Google will be your friend here.

google....pshhhh - tried that, and you can guess the outcome

Thanks

you cannot use a 95-96 transfer case with a 97+ transmission and vice versa.

 

[abaum565]

^^^good to know.


Now does anyone know how to identify the auto transmission/transfer cases between those years. For the life of me I cannot find any info on this.

That number should work.

Let me know if you get a new one and want to sell the bad one.. I need some rebuildable 2G AWD cores.

How did you verify that number would work for 95-96? That is something I have been trying to dig up info on, but can not seem to find any. Thanks

This is exactly my issue, no one seems to know anything on how to identify these auto tranny's.

We know that you can't use a 97-up in a 95-96 without the matching 97-up transfer case.

I called IPT, and the guy on the phone didn't even know that.

So I am really at a loss. I will have to keep looking for another tranny that is known to have come out of a 96-96 or known to have come out 97-up and get the matching tcase.

I am not comfortable with "it should work". If you know what I mean. How did you verify that it will? If all 2g's are W4A33, then how do you know its from a 95-96?

I'm taking time out of my day to answer a question that benefits me in no way. How much time are you asking me to spend on this. Am I expected to write an essay defending my answer?

If you are not "comfortable" with my answer, which I based on the information that you posted, then you can do whatever you like.

Please don't get upset. You didn't even have to come in here and answer in the first place, I am glad you did though and thank you.

I am not asking you to write an essay. You obviously know something I/we don't about how to identify the difference from the number I posted which would greatly help me. Now this may very well not benefit you at all, but like I said in the original post I am new to auto's, and if I need parts or a rebuild....well? I called you guys as your name is synonymous with dsm auto trans.

I know how hard it is to find these buggers, I have been searching for one for a few months. Finally found one and I had a legitimate question on it which led me here.

You don't have to defend your answer, just elaborate a touch more on it. This is not a part on a car that "it should work" justifies me installing it - chewing up the rear end, and having to start all over again, gaining nothing.

Is there a case difference? output shaft difference, numbering differences, etc. There is no information on the differences out there, that I can find.

Thanks for your time!

2g transmissions are all about the same- you may need to match the output shaft to your t case.

Stay away from the JDM units. They are all over Ebay and will not work (they have a three wire solenoid harness and a stamped steel diff cover).

Your tag should be W4A33- UPQ2, not UP02. This is for 95 and 96. 1FNQ or 1FN are supposedly 97 and 98 (which should still work). Final drives are all 4.021:1

That all said, almost every one that I have ever seen is a UPQ"X".

Exactly what I was looking for. And hopefully this helps out a lot of others as well.

Again, thanks for taking the time to clarify this.
