Torque Converter Control Variable Force Solenoid (T/CON_VFS) Repair Procedures

Inspection

1. 1
   Turn the ignition off.
2. 2
   Disconnect the solenoid valve connector.
3. 3
   Measure the resistance between the sensor signal terminal and the sensor ground terminal.
4. 4
   Make sure the resistance is within specification.

Removal

1. 1
   Remove the air cleaner assembly and air duct. (Refer to Engine Mechanical System - "Air Cleaner")
2. 2
   Remove the battery and battery tray. (Refer to Engine Electrical System - "Battery")
3. 3
   Remove the under cover. (Refer to Engine Mechanical System - "Engine Room Under Cover")
4. 4
   Remove the drain plug (A) and reinstall it after the ATF has completely drained. Drain plug tightening torque: 38.2 ~ 48 N·m

   

   Replace the gasket before reinstalling the drain plug.

5. 5
   Disconnect the breather hose (A) from the valve body cover by disconnecting the clamp (B).

   

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

   Tightening torque: (B) 13.7 ~ 15.7 N·m

   

7. 7
   Remove the bolts.
8. 8
   Disconnect the solenoid valve connector (B) and the oil temperature sensor connector (A) from the valve body.

   Tightening torque: 9.8 ~ 11.8 N·m

   

9. 9
   Remove the solenoid valve support bracket (B) and the valve body mounting bolt (A-1EA).

   Tightening torque: 9.8 ~ 11.8 N·m

   

10. 10
    Remove the torque converter control solenoid valve (A).

    

Installation

1. Install in the reverse order of removal.

   Replace the valve body gasket (A) before reinstalling the valve body cover. Add automatic transmission fluid. (Refer to Hydraulic System - "Fluid") Perform TCM learning after replacing the automatic transmission to prevent slow transmission response, shift shock during acceleration, and jerky start. (Refer to Automatic Transmission Control System - Repair Procedures)
