INFOID:0000000006226901
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 det ected, perform A/T fluid cooler
cleaning. Refer to TM-97, "
Cleaning".
INSPECTION AFTER INSTALLATION
Check A/T fluid leakage. Refer to TM-175, "Inspection".
ADJUSTMENT AFTER INSTALLATION
 Adjust A/T fluid level. Refer to TM-95, "Adjustment".
 Perform decel G sensor calibration when replacing control valve & TCM. Refer to TM-92, "
Special Repair
Requirement".

- Tighten rear extension assembly bolts to the specified torque.
 Refer to the followings when installing oil pan (2) (with oil pan gas-
ket) and clips (1) to transmission case.
CAUTION:
 Never reuse oil pan gasket and oil pan mounting bolts.
 Install oil pan gasket in the di rection to align hole position.
 Install it so that drain plug comes to the position as shown
in the figure.
 Be careful not to pinch harnesses.
 Completely remove all moisture, oil and ol d gasket, etc. from oil pan mounting surface.
- Tighten oil pan mounting bolts to the specified torque in numerical
order shown in the figure after temporarily tightening them. Tighten
necessary oil pan mounting bolts with specified torque.

Oil Pan
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-97, "
