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.
CAUTION:
  • If the control valve body has been replaced, perform TCM configuration. (See TCM CONFIGURATION [GW6A-EL, GW6AX-EL] .)
  • If the control valve body has been replaced, perform initial learning. (See INITIAL LEARNING [GW6A-EL, GW6AX-EL] .)
  • Placing the control valve body connector side pointed downward could damage the control valve body connector part or sensor. If the servicing can only be performed by pointing the control valve body connector side downward, spread shock-absorbing material, which does not produce dust or foreign matter, and place the control valve body connector part and sensor on the table so that they do not directly contact the table.

  8. Drain the ATF. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [GW6A-EL, GW6AX-EL] .)
  9. Remove the oil pan.
    CAUTION:
    • To avoid damaging the control valve body, if there is a large amount of foreign matter at the bottom of the oil pan when the oil pan is removed, replace the oil strainer with a new one.
    • If there is not a large amount of foreign matter at the bottom of the oil pan, the oil strainer does not have to be replaced.
    NOTE:
    • Always use new oil pan installation bolts when re-installing the oil pan because the oil pan installation bolts cannot be reused.

  12. Remove the control valve body.
    CAUTION:
    • Remove the control valve body directly from underneath so that force is not applied to the control valve body connector in the lateral direction.
    • When removing the control valve body component for vehicles with oil cooler No. 2, be careful not to loose the spool valve and the spool valve spring because they may fall off.
