Control Valve Body Removal/Installation

WARNING:
  • A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.
  • Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air.
CAUTION:
  • Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
  1. Disconnect the negative battery cable.
  2. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
  3. Remove the air cleaner bracket. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
  4. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.
  5. Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT .)
  6. Disconnect the oil hose from the oil cooler. (See OIL COOLER REMOVAL/INSTALLATION .)
  7. Disconnect the oil cooler from the transaxle with the water hose connected, and set it out of the way. (See OIL COOLER REMOVAL/INSTALLATION .)
  8. Disconnect the oil hose from the oil pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION .)
  9. Remove the oil pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION .)
  10. Remove the control valve body cover. (See CONTROL VALVE BODY COVER REPLACEMENT .)
    NOTE:
    • Disconnect the solenoid connector according to the following procedure
      1. Insert a precision flathead screwdriver from the backside into the connector as shown in the illustration.
    CAUTION:
    • Do not damage the solenoid valves and connectors with the flathead screwdriver.

      1. ii. Pry the flathead screwdriver in the direction of the arrow and disconnect the connector.
    CAUTION:
    • When disconnecting connectors, grasp the connectors, not the wiring harnesses. Otherwise, the wiring harnesses may be pulled out of the connector causing poor contact.
