I have an 84 C10 truck I use as a parts runner. The turbo 350 tranny is going out. A friend gave me a TH400 tranny in good shape and I am going to swap. Upon first inspection I found the dipstick different, No Problem.

It appears the truck frame has multiple places to mount the crossmember and the length is the same (both long tail housings). So far, So good.

The TH350 has two electrical connectors. One two wire on the passengers side and one 4 wire (3 terminals used) connector on the drivers side. The TH400 only has the 4 wire connector on the drivers side. Uh oh?? It that gonna be a problem?

What else am I going to find? Is the yoke the same?

Right now the truck runs and moves but it won't for long. I want to go into this swap all parts in hand so it will be less painful.

Thanks for the help.
