ABSTRACT:
A continually variable transmission includes a torque converter for producing a hydrokinetic connection between a power source and input shaft, a low gear drive mechanism, a belt drive mechanism arranged in parallel with the low gear mechanism between the input shaft and an intermediate shaft, a forward-reverse gearset, a forward clutch, a reverse brake for controlling operation of the gearset in the direction of its output, and a mode clutch for alternately selecting the torque path between the input shaft and intermediate shaft.
