Transmission Temperature Sensor/Switch: Service and Repair

ATF Temperature Sensor Test/Replacement

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

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

3. Place a transmission jack under the transmission, and lift it up to create clearance between the transmission and front subframe.

4. Disconnect the shift solenoid harness connector.






5. Remove the shift solenoid valve cover (A), the gasket (B), and the dowel pins (C).






6. Remove the shift solenoid harness connector.

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





8. If the resistance is out of standard, replace the ATF temperature sensor and shift solenoid harness; go to step 9. The ATF temperature sensor is not available separately from the shift solenoid harness.
If the measurement is within the standard, install the removed parts; go to step 12.

9. Disconnect the connectors from the shift solenoid valves.






10. Connect the shift solenoid valve D connector (YEL wire) (A) with the ATF temperature sensor (B) on the shift solenoid harness.

11. Connect the shift solenoid valve A connector (BLU wire) (C), shift solenoid valve B connector (ORN wire) (D), shift solenoid valve C connector (GRN wire) (E), and shift solenoid valve E connector (RED wire) (F).

12. Install the new O-ring (G) on the shift solenoid harness connector (H), and install the connector in the transmission housing.

13. Install the shift solenoid valve cover, the dowel pins and a new gasket.

14. Check the connector for rust, dirt, or oil, then connect the connector securely.

15. Remove the transmission jack.

16. Refill the transmission with ATF. ATF Replacement
