Manual Control Linkage Adjustment
Move selector lever from ªPº position to ª1º position. You should be
able to feel the detents in each position.
If the detents cannot be felt or the pointer indicating the position is
improperly aligned, the linkage needs adjustment.

2. Loosen lock nuts.
3. Tighten turn buckle until aligns with inner cable, pulling selec-
tor lever toward ªRº position side without pushing button.
4. Back off turn buckle 1 turn and tighten lock nuts to the speci-
fied torque.
Lock nut

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.
IIf 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.
IBe 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.
