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 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.
