M2M,
My uncle has gifted me a 1930? Doodlebug. The front half is Model A while the back half is TT truck. I felt that this overdrive unit had to be something unique. The overdrive unit works fine. I fabricated my own lever to engage it. Can't find a patent date, but the serial # is U3885. I would think it would use 600W lube? Thank you for all of your information.

I have a tractor truck and train transmission like you described in a 1915 T dogcatchers waqon that also has rocky mountain brakes. The T was delivered to the city of Los Angeles with a Hercules body similar to a delivery body with wire mesh sides. Until I read this I had been unable to find anyone who know anything about it.Does anyone know about an overdrive unit made by the Tractor Train Co. of Indiana? The unit is located between the transmission and the differential. Any information would be appreciated.
