Converter Clutch Solenoid
Disconnect harness connector to Torque Converter Clutch (TCC) solenoid. Measure resistance between TCC solenoid terminals. Solenoid resistance should be greater than 20 ohms. See Figure.
NOTE:
Some solenoids have an internal pressure switch in series with the solenoid winding and will not show continuity until that pressure switch is applied by transmission hydraulic pressure.
