I'm doing a m6 to 4l60e conversion and i just want any kinda advice or tips that you guys can give me before we get started. what parts will i need like harnesses or anything else. by the way the tranny is manual valve body and vacuum modulated to that pretty much takes care of any computer stuff right? what will i need? thanks guys.

 

If you are going with full manual control and vacuum modulation you eliminate a lot of the computer issues. My GUESS is that you could leave your M6 PCM in there and just wire around the nuetral safety switch and back-up lights.

There are a couple sticky threads on the switch. One at the top of this forum; one on the M6 forum.

Good luck with the swap and the tranny. 427 + spray is a lot on these trannies.
