●

Completely remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface.

b.

Install oil pan (with oil pan gasket) to transmission case.

CAUTION:

●

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 old gasket, etc.
from oil pan mounting surface.

c.

Tighten oil pan mounting bolts to the specified torque in numeri-
cal order shown in the figure after temporarily tightening them.

CAUTION:

Do not reuse oil pan mounting bolts.

16. Install drain plug to oil pan.

CAUTION:

Do not reuse drain plug gasket.

17. Pull up A/T assembly harness connector.

Removal

1.

Disconnect the battery cable from the negative terminal.

2.

Disconnect heated oxygen sensor 2 harness connector.

3.

Drain ATF through drain plug.

4.

Remove oil pan and oil pan gasket.

5.

Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. 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 

AT-14, "A/T Fluid Cooler Cleaning"

 .

6.

Disconnect A/T fluid temperature sensor 2 connector.

CAUTION:

Be careful not to damage connector.

7.

Straighten terminal clip to free A/T fluid temperature sensor 2
harness.
