7. Check foreign materials in oil pan to help determine cause of
malfunction. If the fluid 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 may inhibit pump pressure.
I
If frictional material is detected, replace radiator after
repair of A/T. Refer to LC section (“Radiator”, “ENGINE
COOLING SYSTEM”).
