A power split powertrain for a hybrid-electric vehicle powertrain has first and second electric machines disposed on opposite sides of a central support wall having a peripheral edge anchored to a transmission housing and a center region rotatably supporting rotors of the two electric machines on opposite sides of the support wall. A power split gearset is disposed adjacent to the first electric machine such that the first electric machine is between the first support wall and the power split gearset. A brake clutch associated with the second electric machine is mounted to the support wall and the support has a hydraulic feed channel supplying the brake clutch. Resolvers associated with the electric machines are mounted to the support wall and electrical connections with the resolvers are integrated with the support wall. A multi-step transmission assembly receiving torque from the power split gearset is also enclosed by the transmission housing.
