ok i just recently bought a 94 z28 that has a lt1 out of a 96 impalla ss in it. engine runs flawlessly.
but i'm having some issues wit the transmission. supposably the car has a performance shift kit in it.
what the car is doing under normal driving conditions it shifts fine but when im on it the revs hit about 5000 then hesitates for a second then shift hard...its chirps the wheels 1-2 and spins them once i kick it down from 3-2 it has a full corsa cat back, jet performance tuner chip, and a 2in loweing kit. i need help

 

you'll get better answers if you post this in the 4th gen section..this is for problems posting in the forum.

 

Actually 'General Tech' will probably be best for transmission issues.

Oh...look at that...we're in General Tech now
