Abstract: A powertrain includes an engine, a transmission, a pump for providing pressurized hydraulic fluid and a launch clutch connected between the engine and the transmission for coupling the engine to the transmission when the launch clutch is in an engaged condition and for decoupling the engine from the transmission when the launch clutch is in a disengaged condition. A device is rotationally coupled to the engine and to the pump. The device is translatable along an axis between a first position and a second position. The device moves the launch clutch to the engaged condition when in the first position and does not move the launch clutch to the engaged condition when in the second position. A piston in communication with the pressurized hydraulic fluid provided by the pump is configured to translate the device along the axis between at least one of the first and second positions.

Abstract: A transmission is provided having a housing, a plurality of planetary gear sets, a structural member, a sprocket member, an annular drum, a band, and an actuator. The sprocket member is rotationally supported by the structural member. The annular drum is adjacent the structural member and is continuously rotationally coupled with a member of the one of the plurality of planetary gear sets. The band circumscribes the annular drum and includes at least a first position and a second position. In the first position the band is substantially separated from the drum and in the second position the band contacts the drum. The actuator selectively positions the band between at least the first position and the second position to transfer torque between the structural member and the annular drum.
