ABSTRACT:
Improvements to a Shiftless, Continuously-Aligning Transmission (SCAT) to provide the turbine member of a torque converter with variable torque-increasing gearing and give it additional work advantage over a work load and eliminate a vast amount of slippage in the converter, the improvements embodying reactive planetary gears mechanically engaging the turbine to a sun gear of a planetary gear set; mobile ring gears controlled by a drive shell extending rearward and engaged to a mechanical ring gear modulator which controls the direction and speed of the planetary ring gears to vary the output torque being delivered by the converter; a two-section input turbine shaft; a clutch mechanism to engage the two turbine shaft sections; a clutchless, continuously engaged overdrive planetary unit; hydraulic controls; and electrical braking controls.
