4.

Remove oil pan and oil pan gasket.

5.

Remove magnets from oil pan.

6.

Check foreign materials in oil pan to help determine causes of
malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates 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-16, "A/T Fluid Cooler Cleaning"

 .

7.

Disconnect terminal cord assembly connectors.

CAUTION:

Be careful not to damage connector.

8.

Disconnect A/T fluid temperature sensor 2 connector.
