Torque Converter Clutch Solenoid: Testing and Inspection

NOTE: Lock-up Control Solenoid Valves A and B must be removed or replaced as an assembly.

1. Disconnect the Connector from the Lock-up Control Solenoid Valve A/B.





2. Measure the resistance between the No. 1 Terminal (Solenoid Valve A) of the Lock-up Control Solenoid Valve Connector and Body Ground, and between the No. 2 Terminal (Solenoid Valve B) and Body Ground.

Resistance: 12 - 24 Ohms

3. Replace the Lock-up Control Solenoid Valve assembly if the resistance is out of specification.
4. If the resistance is within the standard, connect the No. 1 Terminal of the Lock-up Control Solenoid Valve Connector to the Battery Positive Terminal. A clicking sound should be heard. Connect the No. 2 Terminal to the Battery Positive Terminal. A clicking sound should be heard. Replace the Lock-up Control Solenoid Valve assembly if no clicking sound is heard.
