6. Place transmission into Tool with the control valve facing up.
7. Check foreign materials in oil pan to help determine cause of
malfunction. If the fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)

indicates 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 section (ªRadiatorº, ªENGINE
COOLING SYSTEMº).
