  Warning
  • A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until then 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.
  • Do not damage the terminals.

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. Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

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

8. 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].)

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

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

11. 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.
