A system and method is disclosed for engine starting and transmission shifting where a controller may be operable to decrease a torque of a motor and operate a starter-generator (ISG) to start an engine responsive to a command to shift the transmission and start the engine. The controller may disengage a second clutch and subsequently shift the transmission to a target gear ratio speed responsive to the torque of the motor achieving zero. The controller may increase respective torques of the motor, ISG, and engine to drive a speed of the motor, ISG, and engine toward a target speed defined by the target gear speed responsive to completion of the shift. The controller may engage the second clutch responsive to the speed of the motor achieving the target speed and engage a disconnect clutch responsive to the respective speeds of the ISG and engine achieving the target speed.
