id051311710600

On-Vehicle Removal (Without i-stop)

Warning

• A hot transmission and ATF can cause severe burns. Turn off the engine and wait until they are cool before replacing ATF.

• 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

• Clean the transmission exterior thoroughly with a steam cleaner or cleaning solvents before removal.

• If any old sealant gets into the transmission during installation of the oil pan, a malfunction may occur in the transmission case and oil pan. Clean with cleaning fluids.

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2. Drain the ATF. (See AUTOMATIC TRANSMISSION FLUID (ATF) REPLACEMENT [SJ6A-EL].)
