7. Check foreign materials in oil pan to help determine cause ofmalfunction. 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 (ªRadiatorº, ªENGINE
COOLING SYSTEMº).
8. Remove torque converter clutch solenoid valve and A/T fluid temperature sensor connectors.
I Be careful not to damage connector.
9. Remove oil strainer.
a. Remove oil strainer from control valve assembly then remove O-ring from oil strainer.
b. Check oil strainer screen for damage.
10. Remove control valve assembly.
a. Straighten terminal clips to free terminal cords then remove terminal clips.
