I'm the proud owner of a (1950) 3100, restoration project for my son and me. Turns out to be a bit of a FRANKENSTEIN truck. The title says 1950, but it appears to me to have several body parts from a 1949/ Not too unusual since all these things interchange. The original 216 has also been replaced with a 1962 model 235. GREAT, now I don't have to replace the old babbit bearing engine myself. It's also been changed to a 12V system. To top it all off, the original torque tube is gone, replaced with an open rear end. The REAL MYSTERY lies with the transmission. It APPEARS to be a heavy duty MUNCIE 3 SPEED. The only number I've been able to see good enough to read is on the passenger side of the housing casting (GM3 6273262). This transmission has an additional mounting hole on the top! (Which wasn't used in this application by the way). My Dad looked at it and said he thought the tranny was possibly from an olds or buick. From the scant information I can find on the 'net, this tranny may have come from a '52 or '62 cadillac!
Does anyone have a good refernce for identifying this beast?
Thanks,
Bluedawg

Not likely from an Olds or Buick either unless it was a small one like an F85 or something. Does it have a fine spline output shaft? | | |

It had synchromesh on all 3 forward gears, and was a bolt in replacement to the standard truck bell housing. | | |
