Patent ID: 8591364

Claim:
A transmission for a vehicle, the transmission comprising: an input member; an output member; a plurality of planetary gear sets each having a first, a second, and a third member; a launch clutch selectively engageable to connect the input member with an engine output of the vehicle; a plurality of torque transmitting devices each selectively engageable to connect at least one of the first, second, and third members of at least one of the plurality of planetary gear sets with at least one other of a stationary member and the first, second, and third members of at least one of the plurality of planetary gear sets; a plurality of actuators, wherein each of the plurality of actuators includes a cylinder and a piston that is translatable to actuate one of the launch clutch and at least one of the plurality of torque transmitting devices, and wherein the piston of each of the plurality of actuators is substantially rotationally stationary with respect to the cylinder, and wherein a first of the plurality of actuators is configured to selectively actuate the launch clutch; an apply through bearing disposed between the first of the plurality of actuators and the launch clutch; and a sealed hydraulic control system in fluid communication with the plurality of actuators, and wherein the plurality of actuators and the plurality of torque transmitting devices are selectively engageable to establish a plurality of forward speed ratios and at least one reverse speed ratio between the launch clutch and the output member.
