[QUOTE="patooyee, post: 467637, member: 483"] Here's that video I was talking about. He did it with a 4l80 but like I said, its all the same crap at the transmission. [url=http://www.youtube.com/watch?v=ozbWf_QsPrw#]4l80e full manual with no computer[/url] Here's an excerpt from GM's 4t65 performance build book: "[i]An easy and cheap way to shift the 4T65E is with two toggle switches. The toggle switches need to switch ground to pins A and B in the pass through connectors. To operate the transmission turn both switches on. This will put the transmission in 1st gear.
