To solve the transmission problems with a new final transmission design, Warren Rice, creator of the Buick Dynaflow transmission, was consulted. A unique continuously variable transmission called the "Tuckermatic" was designed, which was strong enough to handle the Franklin O-335's power and torque. It was a simple but effective design with a single, rear-mounted torque converter and only 27 basic moving parts which was about 90 fewer than normally required for a contemporary automatic. The variable pitch torque converter allowed a continuously variable drive ratio with two forward gears and one reverse gear.
