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.
