Trans swap?
My truck has the 700r4 trans and I cant get one but I did find both the 350 and 400 at my local juckyard at a price that I can afford. Now will either of these work in my truck? I know after searching online that with the 400 I would have to get either the 9" tail piece or a longer driveshaft but what about the electrical connections? Will the truck still run right with these other trans in it?
The 700r4 is a fully hydraulic transmission, no wires or transmission control modules to worry about. Depending on the engine you have, a turbo 350 should run in your truck no problem. The 400 isn't as much of a bolt in as the 350 though. Also, keep in mind the 700r4 is a 4 speed transmission, and the 350 is a 3 speed, so your fuel mileage will suffer. But, the 350 is a lot more bulletproof than the 700r4. It all depends on what your willing to sacrifice.
