Transmission Fluid Temperature Sensor

Inspection
1. Refer to Replacement Procedure below, for removal of the transmission fluid temperature sensor.




2. Wrap the transmission fluid temperature sensor, place it in water with a thermometer as shown, and heat the water gradually.




3. Measure the resistance between the terminals of the transmission fluid temperature sensor.
4. If not correct, replace the transmission fluid temperature sensor.
5. Refer to Replacement Procedure for installation of the transmission fluid temperature sensor.

Replacement Procedure

WARNING: Be careful when draining; the ATF is hot.

1. Disconnect the negative battery cable.
2. Disconnect the solenoid valve connector.




3. Loosen the oil pan mounting bolts and drain the ATF into a suitable container.
4. Remove the oil pan.
5. Remove the transmission fluid temperature sensor from the control valve body.
6. Remove the control valve body.

NOTE:
The transmission fluid temperature sensor is part of the solenoid valve harness.




7. Remove the solenoid valve harness from the transmission case.
8. Apply ATF to a new 0-ring and install it on the solenoid valve harness.
9. Install the new solenoid valve harness into the transmission case.
10. Install the control valve body.




11. Install the transmission fluid temperature sensor onto the control valve body.




12. Clean the oil pan and the magnet, and set the magnet into the oil pan.
13. Remove any old locking compound from the bolt holes.
14. Install a new gasket and the oil pan.

Tightening torque:
6.9-8.8 N m (61-78 in.lb.)

15. Tighten the new bolts evenly and quickly.
16. Connect the solenoid valve connector.
17. Fill the transmission with the specified amount and type of ATF.
18. Connect the negative battery cable.
