Abstract
A power transmission includes three interconnected planetary gearsets and five selectively engageable torque-transmitting mechanisms. The planetary gearsets and torque-transmitting mechanisms are disposed within a transmission housing. The torque-transmitting mechanisms are selectively engageable to provide six forward speed ratios and one reverse speed ratio in the planetary gearsets between an input shaft and an output shaft.
