COMPONENTS
REMOVAL AND INSTALLATION
Removal 1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-24, " Removal and Installation " .
3. Drain the A/T fluid. Refer to AT-17 .
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
• If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-38 .
