Question on th 350 tranny - The 1947 - Present Chevrolet & GMC Truck Message Board Network

stick · 03-03-2005, 04:35 PM

I'm a new member and have a friend that just bought a th 350 tranny with a lockup converter out of an '80 Chevrolet half-ton. He has put it in a '55 Nomad with a new small block GM crate engine. Two questions. I'm assuming, in calculating which speedo gear he needs, that the th 350 has an 8 tooth drive (not driven) gear. I think the truck was a two wheel drive. Is that correct?

Also, there is a single green wire coming out of the transmission which we are assuming is the on/off for the converter but we don't have a clue as to how to run the wire. Any ideas on that?
