INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
^ Be careful not to damage connector.
^ Do not reuse drain plug gasket.
^ Adjust bolt hole of bracket to bolt hole of control valve with TCM when installing A/T fluid temperature sensor 2 (with bracket).
^ Refer to the following when installing oil pan (2) (with oil pan gasket) and clips (1) to transmission case.
<---: Vehicle front
<---: Oil pan mounting bolt
CAUTION:
^ Do not reuse oil pan gasket and oil pan mounting bolts.
^ Install oil pan gasket in the direction to align hole position.
^ Install it so that drain plug (3) comes to the position as shown in the figure.
^ Be careful not to pinch harnesses.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan mounting surface.
- Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them. Tighten oil pan mounting bolts to the specified torque.
<---: Vehicle front
Inspection
INSPECTION AFTER REMOVAL
Check foreign materials in oil pan to help determine causes of malfunction. If the ATF 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 can inhibit pump pressure.
^ If frictional material is detected, perform A/T fluid cooler cleaning. Refer to TM-143, "Cleaning". Service and Repair
INSPECTION AFTER INSTALLATION
Check for A/T fluid leakage and A/T fluid level after completing installation. Refer to TM-141, "Inspection". Procedures
