I had my 4l60e completely built. anything from hardened shafts, beast sunshell. perfomance clutches..before i had the car tuned at vector it shifted fine. but after the tune it short shifts when i go from a dead dig in drive. but then if i try to shift it manually most of the time it will bounce off the rev limiter even if i shift way before im supposed to and it wont shift untill i let off the gas. does anyone have any idea why it does this.. i have taken the car back atleast 3 times and it still has the same problem. and i also took the trans back to the guy that rebuilt it and he checked it all over again and everything was fine. if anyone can help me or knows someone that can help me can i have their number. thank you
