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.

Abstract: A hybrid powertrain includes an internal combustion engine and a multi-speed transmission coupled to the internal combustion engine. The multi-speed transmission includes an input member, an output member, and a first, second, third, fourth, and fifth planetary gear set each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes a first, second, third, fourth, and fifth planetary gear sets each having a sun gear member, a planet carrier assembly member and a ring gear member. The multi-speed transmission further includes seven torque-transmitting devices configured to selectively interconnect the first, second, third, fourth, and fifth planetary gear sets with one another in combinations of at least four to establish at least ten forward speed ratios and at least one reverse speed ratio between the input member and the output member.
