i dunno much about this car, its a 96 gp se 4t60e 4 spd. the car came and the trans will not go in reverse or drive, under high engine rpm u feel it trying. if you wait til the car warms up it will work, i took it down the road when it first came at it drove fine, tcc worked good. today i found a vacuum leak on the vacuum module line, repaired it and it changed nothing. my feeling is the pump is going out or weak? any ideas?
