System and method for actuating and controlling a transfer case

A hydraulic control system for a transfer case comprising:

• an actuator for generating fluid pressure;
• a first piston for applying fluid pressure to a first device, the piston in fluid communication with the actuator via a first fluid line;
• a selector piston for applying fluid pressure to a second device, the selector piston in fluid communication with the actuator;
• and
• a shuttle valve positioned between the actuator and the selector piston,
• wherein the shuttle valve is in fluid communication with the actuator via a first and a second selector fluid line and is in fluid communication with the selector piston via a second and a third fluid line.

A method of generating hydraulic pressure for a transfer case comprising:

• generating fluid pressure;
• applying the fluid pressure to an at least one piston;
• and
• controlling the fluid pressure to the at least one piston.

A hydraulic control system for a transfer case comprising:

• means for generating fluid pressure;
• means for isolating an at least one device from the pressurized fluid;
• means for applying fluid pressure to the at least one device;
• means for controlling the pressurized fluid;
• and
• means for sensing fluid pressure.
