Abstract
A powertain includes an engine and torque converter arranged to provide input power to a six speed planetary transmission. The transmission includes a simple planetary gear set and a compound planetary gear set that are selectively interconnected by a pair of fluid-operated clutch mechanisms. Two other selectively engageable fluid-operated clutch mechanisms and three selectively engageable fluid-operated brake mechanisms are provided to control the power input and reaction within the planetary transmission. The clutch mechanisms and the brake mechanisms are engaged in combinations of three to provide six forward speed ratios and at least one reverse speed ratio between a transmission input shaft and a transmission output shaft.
