Fleetwood V8-368 6.0L VIN 9 FI (1982)
Torque Converter Clutch Solenoid: Description and Operation
Solenoid--mounted in the automatic transmission--locks-up the torque converter when activated by the ECM.
When the vehicle reaches a specified speed the ECM energizes the solenoid---causing the torque converter to mechanically couple the engine
to the transmission.
When the brake is applied, or other conditions indicate that the transmission should operate as a normal--fluid coupled--transmission the ECM
de-energizes the solenoid.
