Removal
CAUTION:
When removing the A/T assembly from engine, first remove
the crankshaft position sensor (OBD) from the A/T assembly
upper side.
Be careful not to damage sensor edge.
1. Remove battery negative terminal.
2. Remove exhaust front tube.
3. Remove fluid charging pipe from A/T assembly.
4. Remove oil cooler pipe from A/T assembly.
5. Plug up openings such as the fluid charging pipe hole, etc.
6. Remove propeller shaft. Refer to PD section (ªRemovalº, ªPRO-
PELLER SHAFTº).
7. Remove transfer control linkage from transfer. Refer to TF sec-
tion (ªRemovalº, ªREMOVAL AND INSTALLATIONº).
8. Remove A/T control cable from A/T assembly.

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.
a. Straighten terminal clips to free terminal cords then remove
terminal clips.
