4L60E Swap
 

I know this is really for stock trucks but I am wondering if any of you know what to do. I am building 65 GMC c20 that my uncle had parked in a tree line 40-50 years ago planning to make it drivable again but never got to it. I have a 4L60E and the NP261 transfer case I am going to put behind a small block 350. I know they make stand alone control modules for the transmission but not sure if its the same for the transfer case or if I need a different one. I would also like them to have the wiring harness already then I don't have to run all the wires. Since it has push buttons to change between four and two wheel drive so I will need to put those somewhere. I really don't know where to start and wondered if anybody else has any idea of what to do. Thanks.
