I have a 1976 Chev K10 shortbox 4x4 with a 350 engine and a 4 speed transmition. The transmission is pretty much shot and I need a new pressure plate throw out bearings and a new clutch. So most of this setup is garbage. I have recently had to make the change of moving to the city and this 4 speed really sucks out here and I can still go wheelin with an automatic. Soooo with that said I want to know how I could go with a automatic in this truck. I was looking at a turbo 350 tranny for this year of truck and it was cheap. So what all do I need to do this. I got a mechanic that is going to assist me with this but right now he cant look at nothing because he got injured and cant crawl around under a truck right now.

Automatic transmsisons are one of the hardest things to work on. Luckily you have a Chanvy so the block will match, you just have to make sure you get the right length tail piece and spline. You shoukld be able to rig up the necasary vacuum lines for the vacuum pot and the only other thing wouuld be getting the proper pedals and a crossmember to mount the tranny. You will also need a shifter but a cable shifter should take care of that. It will end up costing you a lot more than getting the manual straight. You could probably even put an underdrive box on it for a granny gear. Look into summitracing.
