Lock-Up Control Solenoid Valves

1. Lock-up control solenoid valves are located on transaxle. See Figure . Disconnect electrical connector at lock-up control solenoid valves.
2. Using ohmmeter, check resistance between terminal No. 1 (solenoid valve "A") or terminal No. 2 (solenoid valve "B") and body ground. See Fig 1 .
3. Resistance should be 14-16 ohms. Replace lock-up control solenoid valve assembly if resistance of either solenoid valve is not within specification.
4. Check lock-up control solenoid valve operation. Ensure solenoid valve body is grounded. Apply battery voltage to terminal No. 1 (solenoid valve "A") or terminal No. 2 (solenoid valve "B").
5. Clicking sound should be heard, indicating solenoid valve operation. Replace lock-up control solenoid valve assembly if either solenoid valve fails to operate.
