|---|---|
| B280 Automatic Transmission Accumulator Solenoid Valve | A solenoid valve is an electro-mechanically operated valve. The valve is controlled by an electric current through the solenoid. This is a normally closed valve that is controlled on/off. |
| 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. |
The solenoid valve directs pressurized fluid to exit the accumulator to apply the clutches for a 1st gear start, during an Auto Start event.
