what transmission do i have?

[Cole]

i just bought a 1986 3/4 ton silverado, it has a 350, but there is so much grime on the transmission and transfer case that i cant get it clean...so can anybody tell me what it should be?

I'd guess 700R4 and Np208, Is it auto or manual?

 

[jekbrown]

if its an automatic and its stock its a 700R4. Don't think they ever put a different on in 86s...

Probably a th400, get under and look at the pan, if its a square w/ a corner cut off its a th350, if its a square its a 700r4, if its vaguely like illinois its a th400.
