  2. Install the dowel pin to the control valve body.
    NOTE:
    • Oil with a color different from the genuine ATF may be adhered to a new control valve body.
    • If the dowel pin remains in the transaxle case, remove the dowel pin from the transaxle case and install the dowel pin to the control valve body.

  3. Install the control valve body so that the parking assist lever component is engaged in the gap between the two surfaces of the spool part of the manual valve.
    CAUTION:
    • Install the control valve body so that the turbine/input shaft speed sensor, output shaft speed sensor, and control valve body connector do not contact the transaxle case.

    Tightening torque 

    • 9-10 N.m {92-101 kgf.cm, 80-88 in.lbf}
  4. Move the manual valve in both directions of the arrow and verify that the manual valve is correctly connected to the parking assist lever component and the slider pin for the range sensor.

    NOTE:
    • If the manual valve only moves in the gap between the parking assist lever component surface and the manual valve surface, the manual valve and the parking assist lever component are correctly engaged.
  5. Install the oil strainer O-rings.
    NOTE:
    • If there is a large amount of foreign material at the bottom of the oil pan, replace the oil strainer with a new one.

    Tightening torque 

    • 9-10 N.m {92-101 kgf.cm, 80-88 in.lbf}
  7. Apply a light coat of silicone sealant (TB1217E or equivalent) to the contact surfaces of the oil pan and transaxle case.

    CAUTION:
    • Clean any remaining silicone sealant on the contact surface of the transaxle case and oil pan, and degrease the sealant area. Otherwise, oil could leak.
  8. Install the oil pan with new bolts before the applied sealant starts to harden.

    Tightening torque 

    • 8-10 N.m {82-101 kgf.cm, 71-88 in.lbf}
  9. Install the oil seal (control valve body). (Refer to OIL SEAL (CONTROL VALVE BODY) REPLACEMENT .)
  10. Install a new hose clamp to the position shown in the figure.
    CAUTION:
    • If the hose clamp is reused it could cause ATF leakage, therefore use a new hose clamp.
    • Install the hose clamp tab to within the range shown in the figure.

    CAUTION:
    • Make sure that your hand does not touch the terminal as the connector terminal could be damaged.
    • Verify that there is no fluid or foreign matter adhering to the connector before connecting the connector.
    • Insert the connector straight as the connector terminal could be damaged.
    • Rotate the connector lever until a click is heard.
  12. Add the ATF. (Refer to AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT .)
  13. Install the air cleaner component. (Refer to INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
  14. Connect the negative battery cable. (Refer to NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION .)
  15. Perform the "TCM CONFIGURATION " (Control valve body Replacement). (Refer to TCM CONFIGURATION .)
    CAUTION:
    • The transaxle does not operate normally if the TCM configuration is not performed. When the control valve body is replaced, always perform the TCM configuration to enable the transaxle to operate normally.
    • When the control valve body is replaced, a U-code DTC is output. After completing the TCM configuration, clear the U-code DTC and verify that no DTCs are output.
  16. Delete the U code and verify that no DTC is output. (Refer to ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (EW6A-EL/EW6AX-EL)] .)
  17. Perform the "INITIAL LEARNING " (Control valve body Replacement). (Refer to INITIAL LEARNING .)
  18. Perform the "MECHANICAL SYSTEM TEST ". (Refer to MECHANICAL SYSTEM TEST .)
  19. Install the front under cover No. 2. (Refer to FRONT UNDER COVER No. 2 REMOVAL/INSTALLATION .)
  20. Perform the "ROAD TEST ". (Refer to ROAD TEST .)
