Abstract
A powertrain has an engine and torque converter that provides power to a multi-speed planetary transmission. The transmission includes a compound planetary gear set and a simple planetary gear set that are selectively interconnected by a plurality of selectively engageable torque transmitting mechanisms. The planetary carrier assembly member of the compound planetary gear set is continually connected to be driven by the torque converter, and the ring gear of the simple planetary gear set is connected to continually drive the transmission output shaft. A plurality of torque transmitting mechanisms, including the interconnecting mechanisms, are selectively engaged in combinations of three to establish six forward speed ratios and a reverse ratio.
