I have a 95'Z A4 and the other day i was driving and at WOT the trans would not upshift into 2nd. The car would just hit revlimiter. When the rpm's get to 5800 in 1st it feels like the trans just lets go and it sends u into the steering wheel. under normal driving the trans shifts fine. Even when it down shifts into 1st it hits revlimiter. Has anyone ever had this problem?
There's a very informative thread on www.z28.com under the 4th Gen LT1 Drivetrain section titled, 'No upshift, please help' and I reccomend you read it.
