ABSTRACT:
A planetary transmission has a plurality of rotating-type torque-transmitting mechanism that are operable to connect a rotating input mechanism with one or more planetary gear members. At least two of the rotating-type torque-transmitting mechanisms are radially stacked and axially aligned. At least one of the radially stacked rotating torque-transmitting mechanisms has an apply piston that is slidably mounted in a stationary transmission housing, an apply plate that is rotatable with a portion of the torque-transmitting mechanism, and a bearing disposed therebetween to accommodate relative rotation therebetween.
