Overdrive Solenoid: Description and Operation
CIRCUIT OPERATION
The Torque Convertor Clutch (TCC) solenoid, overdrive solenoid and variable force solenoid are molded together. They are only used on
four-speed automatic transmissions. 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 on circuit K54. Circuit K54 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.
