Hey all, I am trying to help a friend of mine with his '91 Camaro RS. It has a SBC 305 and is an auto with a TH700R4 tranny. First the reverse and 2nd gear went out, which I heard is controlled by a 2-R band or something thats connected. Well, now the tranny has dropped to only having first. Question is would an tranny say from a 1987 Caprice (305) work? Would there be any differences like a "short" or "long" version of the tranny? Or any wiring differences? Thanks for any info!!
