well we dropped a 383 ls1 into a 97 gmc truck. has a "built" 4l60e behind it. today he lost 4th gear all the way won't go in it at all. at one point all the gears were out including reverse. he shut it off for a few, started it back up and all gears were there again. then later on he lost 3rd along with forth.
also since we installed it if the torque converter locks the whole truck shake very badly. so i had to program it to stay unlocked. what could this be? just bad pressure?
