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 indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and may inhibit pump pressure.
+If frictional material is detected, replace radiator after
repair of A/T. Refer to LC-16, section ªRadiatorº.
