id0517k3331900

  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 [MZI-3.7].)

3. Remove the air cleaner bracket. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

4. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.

5. Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [AY6A-EL, AY6AX-EL].)

6. Disconnect the oil hose from the oil cooler. (See OIL COOLER REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

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 [AY6A-EL, AY6AX-EL].)

8. Disconnect the oil hose from the oil pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

9. Remove the oil pipe component (transaxle side). (See OIL COOLER REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

10. Remove the control valve body cover. (See CONTROL VALVE BODY COVER REPLACEMENT [AY6A-EL, AY6AX-EL].)

  Note
  • Disconnect the solenoid connector according to the following procedure:
    i. Insert a precision flathead screwdriver from the backside into the connector as shown in the figure.

      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.

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