Hang down output speed senso r harness toward outside so
as not to disturb installation of the control valve & TCM.
Adjust A/T assembly harness connector of the control valve
& TCM to terminal hole of transmission case.
Assemble it so that manual valve (1) cutout is engaged with manual plate (2) projection.
- Install bolts and clip (1) to the control valve & TCM. Tighten bolt (E) to the specified torque before tightening the other than bolts.
*: Reamer bolt
Refer to the following when installing oil pan to transmission case.CAUTION:
Clean foreign materials (gear wear particles) that adhere on the inside of the oil pan and on the
magnet, and then assembly.
Completely remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface of
transmission case and oil pan.
Never reuse oil pan gasket and oil pan mounting bolts.
Install oil pan gasket in the di rection to align hole position.
- Tighten the oil pan mounting bolts to the specified torque in the numerical order as shown in the figure after temporarily tightening
them.

Inspection and Adjustment
INFOID:0000000006226901
INSPECTION AFTER REMOVAL
Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
If frictional material is det ected, perform A/T fluid cooler
cleaning. Refer to TM-97, "
Cleaning".
INSPECTION AFTER INSTALLATION
Check A/T fluid leakage. Refer to TM-175, "Inspection".
ADJUSTMENT AFTER INSTALLATION
Adjust A/T fluid level. Refer to TM-95, "Adjustment".
Perform decel G sensor calibration when replacing control valve & TCM. Refer to TM-92, "
Special Repair
Requirement".
