Three solenoid valves are located in the valve block. The solenoid valves are controlled by the TCM and converts electrical signals into hydraulic control signals to control dog clutch application.

The solenoid valve is an open/closed, on/off solenoid which is controlled by the TCM switching the solenoid to earth. The TCM also supplies power to the solenoid. The TCM energizes the solenoid in a programmed sequence for clutch application for gear ratio changes and shift control.

The resistance of the solenoid coil winding for solenoid is between 10 to 11 Ohms at 20 °C (68 °F).
