Control Valve Body Removal/Installation

WARNING: This page is about a different variant/trim than selected.
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 pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION .)
  7. Remove the oil pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION .)
  8. Remove the control valve body cover. (See CONTROL VALVE BODY COVER REPLACEMENT .)
    NOTE:
    • Disconnect the solenoid connector according to the following procedure:
      • Insert a precision flathead screwdriver from the backside into the connector as shown in the figure.

    G08143193
    CAUTION:
    • Do not damage the solenoid valves and connectors with the flathead screwdriver.
    • Pry the flathead screwdriver in the direction of the arrow and disconnect the connector.

      G08143194
    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.
  9. Disconnect the solenoid connectors, VSS connector and the input/turbine speed sensor connector.

    G08143202
    NOTE:
    • Be sure to secure the coupler component with tape so that it will not interfere with the control valve body component.
  17. Fix the VSS wiring harness with tape to the transaxle case as shown in the figure.
    Fig 11: Identifying Tape And VSS Wiring Harness
    G08143203
    NOTE:
    • Be sure to secure the VSS with tape so that they will not interfere with the control valve body component.
  18. Connect the manual valve link and install the control valve body component.
