Installation
+Drive plate runout
CAUTION:
Do not allow any magnetic materials to contact the ring gear
teeth.
Maximum allowable runout:
Refer to EM section (ªInspectionº, CYLINDER
BLOCKº).
If this runout is out of specification, replace drive plate with
ring gear.
+When connecting torque converter to transmission, measure
distance ªAº to be certain that they are correctly assembled.
Distance ªAº:
Refer to SDS, AT-1210.
+Install converter to drive plate.
+After converter is installed to drive plate, rotate crank-

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)
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.
+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.
+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.
