Torque Converter Clutch (TCC) Solenoid
See MISCELLANEOUS PCM/VCM CONTROLS.
Disconnect harness connector to TCC solenoid. Measure resistance between TCC solenoid terminals. Solenoid resistance should be 10-15 ohms at 68°F (20°C).
Note. Some solenoids have an internal pressure switch in series with solenoid winding and will not show continuity until transmission hydraulic pressure is applied.
