Inspection

1. 1
   Turn the ignition switch to the OFF position.
2. 2
   Disconnect the battery and battery tray. (Refer to Engine Electrical System - "Battery".)
3. 3
   Disconnect the connector (A) from the solenoid valve.

   

4. 4
   Measure the resistance between the sensor signal terminal and the sensor ground terminal.
5. 5
   Check that the resistance is within specification.

DEPOSIT

1. 1
   Disconnect the battery and battery tray. (Refer to Engine Electrical System - "Battery".)
2. 2
   Remove the under cover. (Refer to Engine Mechanical System - "Engine Compartment Under Cover")
3. 3
   Remove the drain plug (A) and reinstall it after draining all the ATF. Drain plug tightening torque: 33.3 ~ 43 N·m

   

4. 4
   Remove the wiring support bolt (A) or clip.

   Tightening torque: 9.8–11.8 N·m

   

5. 5
   Disconnect the breather hose (A) from the valve body cover.

   

6. 6
   Remove the valve body cover (A).

   Tightening torque: 11.8 ~ 13.7 N·m

   

7. 7
   Disconnect the oil temperature sensor (A) and the solenoid valve connector (B) from the valve body.

   Tightening torque: 9.8–11.8 N·m

   

8. 8
   Remove the solenoid valve bracket (B) and the valve body mounting bolt (1 pc).

   Tightening torque: 9.8–11.8 N·m

   

9. 9
   Remove the torque converter control solenoid valve (A).

   

REMEDY

1. 1
   To install, perform the removal procedure in reverse order.
2. 2
   After filling the automatic transmission with fluid, check the fluid level. (Refer to Hydraulic System - "Fluid")
3. 3
   Perform the TCM adaptive value learning procedure. (Refer to Automatic Transmission Control System - "Repair Procedures")
