I have a 2002 Z28 with an A4. I put a diablosport programmer on the car and firmed up the shifts but after about a month I went in and firmed up the shifts even more. After I firmed up the shifts more the car started shifting slowly into second gear and then it got to where it will not shift at all without letting off the gas.

I pulled the Predator off the car and returned it back to stock and it still does the same thing. Now whenever it is in second it is like it is in neutral. It does not pull at all. WTF?

Does anyone know whats going on?

 

Sounds like the 2-4 band is fried thats really about all it can be that I can think of

 

I was thinking it was something internal too. Anyone else know anything?

 

I would have to say that the band is toast or you have a cracked 1-2 accumulator piston or both. We do offer rebuilds and parts if you need. Please take some time to see what we have to offer. Vince http://finishlinetrans.com/index.htm
