A hydraulic shift system for a four-wheel drive transfer case is disclosed. The hydraulic shift system includes a pump, a pressure regulator, an accumulator, a control valve, a range shift assembly, a mode shift assembly, and a shift actuator. The pump supplies hydraulic pressure to the accumulator which is in communication with the control valve. The shift actuator controls the delivery of hydraulic pressure from the control valve to the range shift assembly and the mode shift assembly in response to actuation by the vehicle operator of a mode select mechanism.
