Claim:
A vehicle transmission comprising: an input member; an output member; a plurality of gear sets disposed between the input member and the output member; a first clutch selectively engaged to rotationally couple a first set of the plurality of gear sets; a first actuator having a first stationary cylinder bore and a first nonrotating piston disposed in the first stationary cylinder bore, wherein the first piston is substantially rotationally stationary; a first bearing disposed between the first clutch and the first nonrotating piston of the first actuator; a second clutch selectively engaged to rotationally couple a second set of the plurality of gear sets; a second actuator having a first stationary cylinder bore and a second nonrotating piston disposed in the stationary cylinder bore, wherein the second piston is substantially rotationally stationary; and a second bearing disposed between the second clutch and the second nonrotating piston of the second actuator, wherein the first piston has a first diameter substantially the same as a second diameter of the second piston.
