Will a TH475 Transmission fit my 1989 Chevrolet suburban V1500 4x4?

Hey y’all how y’all doing I’m new here but I burnt my 700R4 on my 89’ Suburban 4x4 and need to find a replacement and I had my friend who has bunch of suburbans say he has a TH475 with 8k miles on in and replaced filters and the works but I don’t know if it will fit. I wanna know if it will be a direct bolt on Because this is for my daily driver too and right now I’m stuck in first and it sucks not being able to go past 35 mph
So if anyone can tell me anything I’d really appreciate it
Thanks y’all

The short answer is no. The TH475, a 3 speed trans from a medium duty, most likely has bolt on drive shaft yoke for a rear drive truck. Can be changed to a slip yoke but you need a trans that will mate to your transfer case.

Since you have a 700R4, this becomes a much more expensive swap.

Some TH475's will have an E-brake bolted to the tail shaft. The TH475 also has straight cut planetary gears instead of helical cut gears like a TH400. The reason for this is more in-depth, but the result is louder gears.
