Abstract
A vehicle transmission includes an input member, an output member, a plurality of gear sets, first and second clutches, first and second actuators, and first and second bearings. The plurality of gear sets is disposed between the input member and the output member. The first and second clutches are selectively engaged to rotationally couple first and second pairs of the plurality of gear sets. The first and second actuators each have a stationary cylinder bore and a piston disposed in the stationary cylinder bore, where the pistons are substantially rotationally stationary. The first bearing is disposed between the first clutch and the nonrotating piston of the first actuator and the second bearing is disposed between the second clutch and the nonrotating piston of the second actuator.
