Will a turbo 400 transmission fit on a 1978 trans am 403?
no , look for a 200r4 trans which has overdrive and the same lenghth as the th350Wow...completely wrong answer. The 200-4R is the same length as the TH400. Not the TH350. The 700-R4 is the same length as the TH350. And yes....a B.O.P. TH400 will fit that 403 just fine. You'll have to locate a transmission cross member for the TH400 if it was originally a TH350.
What kind of transmission can you put in a 79 Chevy truck?
just about any Chevy trans, a TH350 or a TH400 are the most common and will both fit. as far as engines and transmissions with Chevy's there just about all interchangeable without to much messing around. only difference with a TH350 to a TH400 is that a 400 will take higher horsepower/torque. but for most stock applications a TH350 will be fine , oh and the TH400's are slightly longer to.

What transmission will fit a 1971 Chevy c-10?
In an automatic version it will either be a TH350 or TH400. Both will bolt to the engine, the trans cross member may be different though. Some of the older vehicles had additional holes in the frame for moving the cross member for the different length transmissions.
What transmission will bolt to a 1978 301 Pontiac motor?
Any automatic trans from Buick, Oldsmobile, Pontiac or Cadillac will bolt right up. A Chevy transmission will NOT bolt up without and adapter. If you change from a TH350 to a TH400 you will have to change your drive shaft yoke and the cross member. Unless you just have one lying around, or find and extremely good deal on one, there is just about no reason to put a TH400 behind a 301.
