Coupler Component Removal/Installation

WARNING:
  • A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.
  • Always wear protective eye wear when using the air compressor. If the air compressor is used, any particles of dirt or sludge could spatter and get into the eyes.
CAUTION:
  • Placing the control valve body connector side pointed downward could damage the control valve body connector part or sensor. If the servicing can only be performed by pointing the control valve body connector side downward, spread shock-absorbing material, which does not produce dust or foreign matter, and place the control valve body connector part and sensor on the table so that they do not directly contact the table.

  1. Select the selector lever to P position.
  2. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION .)
  3. Remove the front under cover No. 2. (See FRONT UNDER COVER No. 2 REMOVAL/INSTALLATION .)
  4. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.
  5. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
  6. Remove the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
  7. Remove the oil seal (control valve body). (See OIL SEAL (CONTROL VALVE BODY) REPLACEMENT .)
  8. Disconnect the coupler component connectors.
    CAUTION:
    • Do not scratch the shift solenoid, shift solenoid connector, oil pressure switch, and oil pressure switch connector with the precision flathead screwdriver.
    • When disconnecting connectors, grasp the connectors, not the wiring harnesses. Otherwise, the wiring harnesses may be pulled out of the connector causing poor contact.

  11. After verifying that the oil strainer installation bolt hole is not deviated, install the coupler component.
    CAUTION:
    • After assembling the coupler component, verify that shift solenoids No. 1, 2, 3, 4, the pressure control solenoid, and the TCC control solenoid cannot be pulled out from the control valve body.
