Re: 72 C10 Transmission information needed

3 speed auto with O/D? 700R4? 200-4R?

There is a lot of info on this in quite a few threads on here. This is a very popular swap.

Re: 72 C10 Transmission information needed

The 200-4r automatic transmission is the same length, output shaft is same spline so same driveshaft will work. you will have to remove the bellhousing mounted x-member and use a x-member at the transmission, either get a floor shifter or change column from 3 OTT to an auto. then of course trans. cooling lines to the radiator and TV cable and carb bracket for the cable. I did the swap and it dropped my rpms at 55 mph from 2500 to 1900, and thats not locking up the converter.. BTW, WELCOME!!
