Transmission Temperature Sensor/Switch: Service and Repair

ATF Temperature Sensor Test/Replacement

1. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported.

2. Remove the splash shield.

3. Disconnect the shift solenoid wire harness connector.

4. Measure the ATF temperature sensor resistance between shift solenoid wire harness connector terminals No. 6 and No. 7.





- If the resistance is out of the standard, go to step 5, and replace the ATF temperature sensor and solenoid wire harness. The ATF temperature sensor is not available separately from the shift solenoid wire harness.

- If the resistance is within the standard, the test is complete, connect the connector securely, and install the splash shield.





5. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).

6. Reinstall the drain plug with a new sealing washer (B).






7. Remove the shift solenoid valve cover (A), the dowel pins (B), the gasket (C), and the harness clamp bracket (D).






8. Remove the shift solenoid wire harness (E), and replace it.

9. Install a new O-ring (F) on a new shift solenoid wire harness, and install the connector in the transmission housing.

10. Connect the WHT harnesses and the ORN harness connector to shift solenoid valve B. The ATF temperature sensor is assembled in the connector with WHT harnesses.

11. Connect the shift solenoid valve connectors:
- BLU wire to shift solenoid valve A.

- GRN wire to shift solenoid valve C.

- YEL wire to shift solenoid valve D.

12. Install the shift solenoid valve cover, the dowel pins, a new gasket, and the harness clamp bracket.

13. Check the connector for rust, dirt, or oil, and clean or repair if necessary, then connect the connector securely.

14. Refill the transmission with ATF. ATF Replacement

15. Install the splash shield.
