I bought a pile of T stuff and this transmission was in with it. the output end is a model t universal and fits the driveshaft perfect. It even has the 4 bolt flange that holds the T torque tube to the transmission. the input end is 1 1/8" which is to big to fit into the transmission of a T. It has 3 forward and one reverse. the only markings on it are part numbers 14182A and 14181. I have added some pictures. Any help figuring out what it goes to would be greatly appreciated. Thanks, Doug

Just a guess, but I think for a tractor conversion. Probably used a TT rear axle. Ultimately 6 speed forward

looks like 490 chev.got one out in the shop some where. charley

I googled a 490 transmission and I do believe you are right. thank you both for your time.

Interesting, can that kind of transmission be coupled with a T? If so what are the benefits and or ratios?

Circa 1963, when we were kids in our mid-teens fiddling with Model Ts, on one outing, a grizzled old-timer in bib overalls sidled up to us and announced, "We had a Model T like that when we were kids. We put a "Shove-or-lay" transmission in it backwards. Fool thing would go ninety mile an hour !"

Go figure !

Most of Chevrolet's transmissions from the '20s can be adapted rather easily to work in a model T. Chevy also used a torque tube, similar to the T, and the bell coupler and U-joints can be mixed and matched several ways to use different Chevy transmissions in different ways. These were often used for easy gearing mounted in the usual direction, both in cars, trucks, and doodle-bug tractors. And, they were sometimes used as an overdrive, by mounting backwards.
Many years ago, at a Turlock swap meet, a fellow had a Chevy transmission that had years earlier been set up as an overdrive. Low and reverse gears were totally removed. Shifter altered to operate only the one (2nd and high) gears shaft. Input and output mountings altered to fit in the drive-line backwards. It was a really slick setup! The only problem was, he wanted a bit more for it than one could buy a good Muncie for at that time. When I think back about it? Sometimes I think he may have been right.
Remember though. That second gear turned around becomes a nearly two-times overdrive! It might work in a 7 to 1 TT. Or maybe a speedster with 4 to 1 and a gutsy engine.
I have always wanted to try it myself, but doubt I will ever get around to it.
