ABSTRACT:
A five speed planetary transmission has a simple planetary gear set, a compound planetary gear set and six torque transmitting devices which are engaged in combinations of three to provide five forward ratios and one reverse ratio. The planetary gear sets are interconnected with a continuous drive connection and one of the torque transmitting devices. Two of the transmitting devices are input clutches and the other three are brakes. The planetary carrier assembly member of the simple planetary gear set is the only member connected with the output shaft during all of the ratios. The ratio interchanges in both single step and double step forward interchanges are of the single transition type.
