I just shipped a trans off that I never did figure out where it came from. I pulled it from my 69 Rambler, 232 sedan. It was tagged S-42, It was aircooled and had the dipstick directly in the case, not screwed into the pan as the other aircooled trans I have are. I always figured S designated it as a Service replacement part, but never verified it. It would have been interesting to go through it and compare it to try to see if it was an upgraded later model trans. Perhaps it even came out of of the postal Jeeps???? Who knows, I'm just glad it found a home in California and is no longer wasting away in my shed!!!! I have two more air cooled trannys if anyone needs or wants them for cores!

But there is a slight problem. The M35/37 air cooled trans was only used behind 199 and smaller sixes in big cars, 232 in the light weight postal Jeeps and early Hornet/Gremlin. They weren't used behind the V-8 at all. The air cooled bell is very different from the radiator cooled models. I'm not sure about depth of the bell either, though I suspect M4x trannys all used the same bell whether behind a six or 290/304. I think the M37 was a heavier air cooled model, but it might be radiator cooled (M35 modified for radiator cooling?).
