The transmission has an input member, an output member, at least four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices include clutches and brakes actuatable in combinations of three to establish a plurality of forward gear ratios and at least one reverse gear ratio. The electric motor is connected to the input of the transmission and the engine is selectively connected to the input member through the disconnect clutch. A controller is configured to control the operation of the powertrain.</p> |
