    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.

    Abstract: A powertrain for a motor vehicle includes a one mode continuously variable transmission (CVT) and a torque converter connected to a planetary gear set assembly which is connected to a pulley and a chain assembly or other continuously variable unit (CVU). The planetary gear set arrangement generally includes one planetary gear set, one brake and one clutch. The CVU is connected to a final drive unit. The sheaves of the CVU have an involute spline connection.

    Abstract: A torque transmitting mechanism for a transmission includes a first and a second rotating member, a rotating piston, a stationary piston, and a first bearing. The rotating piston is rotatably connected to the first rotating member and includes a splined end. The stationary piston is disposed in a stationary housing of the transmission. The stationary piston and the stationary housing form a hydraulic fluid piston apply chamber. The first bearing is disposed between the rotating piston and the stationary piston. The splined end of the second rotating member is axially aligned and configured to engage with the splined end of the rotating piston.

    Abstract: A P2 transmission and engine assembly includes a transverse mounted transmission having: a transmission first end and a transmission second end oppositely positioned with respect to the transmission first end; and a transmission gearbox portion having a first cavity positioned at the second end. A torque converter is positioned at the transmission first end. An electric motor is positioned within the first cavity and is rotatably connected to the torque converter using a turbine shaft. A one-way clutch is connected to the turbine shaft and releasably connects the turbine shaft to the torque converter. The one-way clutch when disengaged disconnects the torque converter from the turbine shaft.
