Grand Cherokee 2WD V8-318 5.2L VIN Y MFI (1994)
Shift Solenoid: Description and Operation
CIRCUIT OPERATION
The Torque Convertor Clutch (TCC) solenoid, overdrive solenoid and variable force solenoid are molded together. Circuit T20 from the
electronic transmission relay supplies power for the solenoids. The Powertrain Control Module (PCM) operates each solenoid individually by
providing ground for each solenoid on separate circuits.
-
The PCM provides ground for the TCC solenoid on circuit T22. Circuit T22 connects to cavity B11 of the PCM.
-
The PCM supplies ground for the overdrive solenoid on circuit T60. Circuit T60 connects to cavity B21 of the PCM.
-
On circuit T59, the PCM provides ground for the variable force solenoid. Circuit T59 connects to cavity B8 of the PCM.
