Paul Marra built a transmission that used a 10-12" inside dia. pipe, as best as I can remember. Inside was a combination of parts. Low gear was power glide drum and band, then direct drive using 4spd manual output shaft, had a sliding coupler to connect the main shaft to the output shaft.(milled a 7* taper on the main shaft with a spring behind the coupler) Used a crank coupler to input shaft, all mechanical, no pump. Paul was always thinking.

Tom Hager personaly served patent infringement papers to the transmission guys at the motorsports show,year?. John Deere tractors used the trans operating idea and paid royalty to use the idea.
