transmission case and oil pan.

• Never reuse oil pan gasket and oil pan mounting bolts.
• Install oil pan gasket in the direction to align hole position.
• Never reuse drain plug and drain plug gasket. In addition, install new drain plug and drain plug gas-

Inspection and Adjustment

INFOID:0000000005250161

INSPECTION AFTER REMOVAL

Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
• If frictional material is detected, perform A/T fluid cooler

cleaning. Refer to 

TM-163, "Cleaning"

.

INSPECTION AFTER INSTALLATION

Check A/T fluid leakage.

ADJUSTMENT AFTER INSTALLATION

Adjust A/T fluid level. Refer to 

TM-161, "Adjustment"

.
