摘要:
A dual path planetary transmission includes two planetary gearsets each having a sun gear member, a ring gear member, and a planet carrier assembly member. Each of the members of the planetary gearsets are selectively connectible between an input shaft, an output drive mechanism, and a stationary member. Each of the planetary gearsets is effective to provide a reverse ratio and five forward gear ratios. The output mechanism of each of the planetary gearsets includes a different gear ratio between the output mechanism and the transmission output shaft.
