ABSTRACT:
A variable compound planetary gearset forms five operational elements by having its single and double pinion planetary gearsets be interconnected by a shared planet carrier. The variable compound planetary gearset forms six forward speeds and one reverse speeds by receiving input torque through two input routes fixedly or variably connected to a simple planetary gearset and one input route variably connected to an input shaft.
