95 z28 a4 is starting to act goofy.. it used to shift really hard with no delay, barking the tires.. now it seems to over-rev and pause before shifting and it seems to lose a lot of power doing that. usually this is between 1-2 but also sometimes 2-3 car has about 88,000 miles on it.. possible causes? could this be a computer thing or does the transmission need some work? thanks in advance for any help and please include prices if u have an idea.

 

Could be the clutches started to feel their age inside the trans

 

I had the same thing happen to me a while back with my T/A.
It only had about 58,000 mi. on it. After a while, it stopped shifting altogether. It ended up being a bad shift solenoid and had to have the whole thing rebuilt. Definatley get it checked out as soon as you can.
