Pressure Regulating Solenoid: Description and Operation
SOLENOID VALVES
The Transmission Control Module has control over 4 solenoid valves: MV1, MV2, torque converter lock up and pressure regulator. These are all
supplied via pin 19, which is activated via a relay in the Transmission Control Module itself.
Pressure Regulator Solenoid (pin 6):
The gear shift quality is controlled by modulating the pressure regulator, which is controlled by the Transmission Control Module. The solenoid is
energized closed, such that if a failure occurs, then the regulator allows default gear change.
