My transmission is slipping and I am going to open it to see why its slipping. My question is how many of you replaced a 4l60e for a 6l80e transmission. or am i better off rebuilding mine again? i want a 6 speed if i have to get a new one and if i do get a new one i want a 3200 stall with a vette servo i want everybodys input negative or positive the pros and cons of getting a 6 spd and or if i should just rebuild the one i have.
