Abstract
A transmission including an electric machine, a torque converter and a planetary gearset in a transmission housing that is connected to an engine. A turbine shaft is configured to transfer torque from the engine and the electric machine to the planetary gear set. A disconnect clutch selectively couples the input shaft from the engine to the torque converter housing of the torque converter. The disconnect clutch includes a disconnect clutch piston and a first balance dam. A torque converter clutch selectively connects the torque converter housing to the turbine and the turbine shaft. The torque converter clutch includes a torque converter clutch piston and a second balance dam. Ports in the housing permit automatic transmission fluid to flow between the turbine shaft and the torque converter clutch piston; the turbine shaft and the torque converter clutch piston; and the turbine shaft, the first balance dam, and the second balance dam.
