Hey guys I'm curious if anyone now's can 2 pcm be ran as in could one use the factory pcm for the trans and run the engine off the 411. Just unsure if 2 pcms would run fine being you would have to have some of the wires tied into both pcms I belive.

In theory yes, but it wont work as well. The engine PCM wont know what the gearbox is doing and the pcm doing the gearbox wont be able to influence spark etc to soften gear changes. You'll also need to spend some time figuring out the minimum of sensors you need for the auto computer to work and what errors codes you need to disable. Engine computer should think the vehicle is manual.

K. Sorry for all the questions. I have access to manuals and such and only real difference I can find in a 4l80e wiring and a 4t65ehd found in are gtp in Canada is 1 TCC wire in the manual valve pressure switch 4l80 has 3 wires for D3,D2-D4,D2-REV,LO and the 4t65 has the same 3 wires on the same D3,D2 patterns but also has a 4th wire labeled TCC Release the 4l65 has TCC release in the brake switch as well. 4l80 only has TCC release on the brake switch dont think this will cause a hug problem. Just seeing what you all think before I jump in on this really interested to try this but trying to get as much info as I can before I jump in with 2 feet. Thx again cheers
