Grand AM L4-144 2.4L DOHC VIN T SFI (1997)
Shift Solenoid: Description and Operation
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.
