Control system for electronic range selection in a dual clutch transmission and for a differential in a transmission

A control system in a transmission comprising:

• a hydraulically actuated axle clutch;
• a source of pressurized hydraulic fluid;
• a first solenoid in fluid communication with the source of pressurized hydraulic fluid;
• a second solenoid in fluid communication with the source of pressurized hydraulic fluid, the second solenoid operable to vary a pressure of a hydraulic fluid from the source of pressurized hydraulic fluid;
• and
• a valve in fluid communication with the first solenoid and with the second solenoid, the valve having an outlet in fluid communication with the hydraulically actuated axle clutch, wherein the valve is moveable between an open condition and a closed condition by the first solenoid, and wherein the outlet is not in fluid communication with the second solenoid when the valve is in the closed condition and wherein the outlet is in fluid communication with the second solenoid when the valve is in the open condition,
• wherein the hydraulically actuated axle clutch is disengaged when the valve is in the closed condition, and
• wherein the hydraulically actuated axle clutch is engaged when the valve is in the open condition, and whether the axle clutch is fully engaged or slipped is based on the pressure of the hydraulic fluid communicated from the second solenoid through the valve to the axle clutch.
