    A buddy of mine just called me and told me the tranny on his 85 is going out. Anyway, what kinda tranny has it got in it, 700R4? It's a 4-speed auto behind a 2.8L. I was reading another post about a tranny swap, did someone say that a V8 700R4 will bolt up to that 2.8L? Also, what's a good used one gonna cost him? Thanks.
