Do you have a lot of self control? Are you disciplined? DO NOT beat on it, take it easy with your right foot and the 4L65 might last. Same thing for the 8.5.

No i don't have any self control much less disciplined :wink: I know for consistant e.t.'s the auto is the way to go but i wanted to upgrade the t56 to these specs:
