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 soiling 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.

  9. 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 flat head 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.
