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 initial learning. (See INITIAL LEARNING .)
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.
