	other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio and torque converter clutch operation.
Q77 Transmission Control Solenoid Valve	A linear solenoid actuator is an electro-mechanical device that converts electrical power into a mechanical pushing or pulling force or motion. The solenoid actuator varies the force depending on the current applied to the solenoid coil. The solenoid actuator applies minimum force with minimum current applied to the solenoid coil. The solenoid actuator applies maximum force with maximum current applied to the solenoid coil.
