    Default Tranny swap questions

    I have nice 89 K1500 with a 4 speed and was wandering what would be involved in swapping to an auto trans. The mechanical part I'm not worried about. What I don't know about is the electrical/computer issues I will run into. Any help on what all needs to be changed would be greatly appreciated.

    I would think that you could swap to a 700r4 or turbo 350, but I'm not sure.

    You can swap in a 700R4 with no electrical problems at all. No computer needed. Just have it wired up to lock up in 4th gear and all you need is 12 volts to the transmission. Have fun!
