Re: Help identifying a 3spd transmission

Thank you all for your replies! I have to admit, I'm never sure what kind of reception to expect when joining a new forum...so it was nice to see things are friendly!

I have searched for information about the 1935-38 3 speed without success. Is there a specific model number associated with the transmission? I'd like to get an idea as to what the gearing was like and if there were any alternatives, but I need a place to start. To be honest, I'd really like to get more gears in it as it currently spins 5000rpm at 60mph. Given the configuration of the car, I'm not sure it is possible to do that with anything but an automatic conversion as the shifter location for most Chevrolet transmissions would move this one's location to under the seat.

I have a similar thread on a Chevrolet truck forum trying to identify the rear end. Near as I can tell, its from a 1947-1954 Chevrolet "Stovebolt" pickup truck. If I can sort that out, I may be able to bring the gearing down by swapping the rear end out.

As far as I can tell, the engine is a 283 small block with a 4 barrel, probably also from a truck. I'd imagine it too was straight from a farm and probably has no internal modifications. Dad used to drag this thing "back in the day"...supposedly running 13.2's in 1962. I have to admit, being born in 1975 and cutting my teeth on cars in the 80's, it's hard for me to wrap my head around exactly why it was made the way it was. I'd have thought you'd pull the drivetrain from a single vehicle, say a '57 Chev sedan...but those were different times.
