id051721294600

Primary Control Valve Body On-Vehicle Removal

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.

1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].)

2. Disconnect the negative battery cable.

3. Remove the aerodynamic under cover No.2. (See AERODYNAMIC UNDER COVER NO.2 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 [FS5A-EL].)

6. Remove the oil pan.

7. Remove the oil strainer.

8. Disconnect each solenoid valve connector and GND.

Caution

• If any old sealant gets into the transaxle during installation of the oil pan, trouble may occur in the transaxle case and oil pan, and clean with cleaning fluids.

8. Install the oil pan before the applied sealant starts to harden.
