Another A4 question

[1 RedHot TransAm]

When I get up to about 45 -55 "it usally varies" i'll hit the gas and the RPM's will fly up and the spedometer will creep up really slow I usually have to punch the gas a little bit to so called "pop it out" to normal this does'nt happen all the time sometimes as low as once a week but some times more I had a trans shop look at it and in there opinion there was nother wrong w/ it any one else know what i'm talking about or might be able to give me an answar, its been do'in this for about a year and a half by the way, Thanks

My Z28 did that. I had the pcm tuned at hypertech tuning and its fine now.

Sounds to me your overdrive might be slipping in and out. Check your tranny fluid and see if it's still red.

Mine does that too but I just figured it was something to conserve fuel consumption or something.
