the A4 in our 95 TA has 108k miles and just had a trans flush/filter
Now it won't shift at wot; 1-2 or 2-3. Normal acceleration it works just perfect. Prior to the flush/filter it worked perfect at wot or normal accel. Are the shift solenoids operating during both normal accel and wot? The fluid level is fine. What is the difference between normal shifts and wot shifting that could cause this? Guess I need to get it scanned to see if there are any codes.
thanks..

Sounds like slipping tranny that needs rebuild. Mine is slipping on 2-3 @ wot. 4th tranny in the last like 4 months...

Took the car to the dealer this a.m. They'll probably try to weasel out of responsibility. But talking to one of the vehicle mechanics here at work enlightened me a bit. If the mechanic did not loosen the trans mount bolt and raise the trans he could have damaged a solenoid or wiring putting the trans pan back on. He also said that a failed solenoid wouldn't necessarily turn the SES light on.
The trans doesn't need a rebuild it hasn't been beat on enough for that. Besides working as well as it does under normal acceleration/deceleration tells me it is something electronic. Hard to find good help these days. Just kidding, the same mechanic usually works on the T/A when I bring it in, he is good. I'm not too lazy to work on my own stuff,sometimes 5 vehicles gets to be to much. Of course the other 4 are low tech and not a pain in the behind to get underneath to work on.

My wife picked the car up at the dealer. They didn't charge anything. They said no codes, there is nothing wrong it shifts fine.HA! On her way home....it won't shift at 3/4 to W.O.T. wtf?
I'm not trying to get anything for free. Just fix the darn thing! Is there a throttle position senor involved in the shifting??

The first thing your wife does w/ the car she gets back from the dealer is take it high enough to need to shift 3-4 at wot!!! You have a keeper my friend! Even w/ 3.73's, 3-4 at wot doesn't come until almost 130 for me. Even higher if you have a lower numerical gear ratio than me. That is AWESOME!

Your wife.

I believe he ment 3/4 throttle not 3rd-4th gear at WOT....I had to read it a time or 2 to get it myself.......

Went to the dealer this a.m. and took a mechanic for a spin. He was baffled, the service advisor had egg on her face.
No codes found. The mechanic said bring it in next week and he'd do some research til then. I like it when I'm right in such an environment where I usually get treated like a dumb @$$.
