I was waiting on the local tranny guy to come back from lunch and his wife said i could talk to his son who was inside working on car and i was talking to him about what extras i wanted in my rebuild and he said that my tranny already had a .490 boost valve and 13 vane pump he asked what year my T/A was i said 99 and he said ya mine already had the .490 and 13vane--i think hes wrong---anybody can verify i sure would appreciate it--thanks i want to rebuild my tranny to handle around 450 hp and i know i'm gonn use the 8 clutch pack from alto as well as kolene steels i want a corvette servo sun gear and whatever else i might need to make it bulletproof-any suggestions from anyone on what to put in tranny sure would be appreciated---thanks in advance
