When I put my car in first and give it gas and then let off, there is bounce. It seems like it's in the tranny though. I can't seem to see it in O/D. Second will do it too, (I have a 2000 ws6 and it'll stay in 2nd when I put it in 2nd). What may go wrong in the tranny at 73,000 miles or so? I had a tranny shop look at it but they said it was normal. It's getting worse and there is no way this is normal. OK experts, diagnose!!! Thanks.
