2-3 Shift Solenoid Valve

The 2-3 Shift Solenoid (2-3 SS) valve functions identically to the 1-2 Shift Solenoid valve in that the PCM controls the ground to the solenoid, commanding it ON or OFF. When the solenoid is OFF, filtered line pressure feeding the solenoid will cease. When energized (ON), the exhaust port is blocked, stopping the exhaust of line pressure and directing it into the 2-3 shift solenoid fluid passage. The 2-3 shift solenoid fluid pressure then feeds to the 4-3 manual downshift valve and the 3-2 manual downshift valve.
