5. Remove oil pan and oil pan gasket.
6. 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.
lIf friction material is detected, replace radiator after repair
of A/T. Refer toCO-11, "
RADIATOR".
7. Support A/T assembly using a transmission jack.
CAUTION:
When setting transmission jack, place wooden blocks to
