11. Remove gusset and rear plate cover securing engine to A/Tassembly.
12. Remove bolts securing torque converter to drive plate.
I Remove the bolts by turning crankshaft.
13. Support A/T and transfer assembly with a jack.
14. Remove rear engine mounting member from body and A/T assembly. Tighten rear engine mounting member to the speci-
fied torque. Refer to EM section (ªENGINE REMOVALº).
15. Remove bolts securing A/T assembly to engine.
I Secure torque converter to prevent it from dropping.
I Secure A/T assembly with transfer to a jack.
16. Lower A/T assembly with transfer.
Installation
I Drive plate runout
Do not allow any magnetic materials to contact the ring gear
teeth. Maximum allowable runout:Refer to EM section (ªInspectionº, CYLINDER
BLOCK).
If this runout is out of specification, replace drive plate with ring
gear.
I When connecting torque converter to transmission, measure
distance ªAº to be certain that they are correctly assembled.
Distance ªAº: 26.0 mm (1.024 in) or more
I Install converter to drive plate.
I After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transmission

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.
