Ok first off. 1994, LT1, 4L60e, all stock minus exhaust.

Furthermore, second gears dead. Gone. Away with the wind. I want to swap to a 4l80e as i hate the 4l60, i know it bolts up, i know it fits, i know the C beam needs modified and im ready and capable of doing so. Im aware i need to use a 32 spine yoke frome an -8p or a 700r4.

What i DONT know is how the wiring harness is gunna work. Can i splice the connectors in? Is there a patch harness i can buy? Do i need a different trans controller entirely?

Im not looking for a bunch of fancy features i want it to run like stock but with the 4l80e. Maybe ill do a 2400 stall or something but nothing more.

Any info you all have would be greatly appreciate as i plan to make this happen one way or another but this will be a new one for me.

Thanks, Blade.
