| K71 Transmission Control Module | The control module contains a microprocessor used to process input data to control outputs.The control module contains a microprocessor used to process input data to control outputs.The control module receives information from a variety of sensors, switches and serial data information from 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.
