INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
^ Be careful not to damage connector when installing any connector.
^ Do not reuse drain plug gasket.
^ Do not reuse O-ring.
^ Apply [1][2]ATF to O-ring.
^ 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 followings when installing control valve with TCM in transmission case.
CAUTION:
^ Make sure that turbine revolution sensor securely installs turbine revolution sensor hole (B).
A: Brake band
^ Hang down revolution sensor harness toward outside so as not to disturb installation of control valve with TCM.
^ Adjust A/T assembly harness connector of control valve with TCM to terminal hole of transmission case.
^ Assemble it so that manual valve (1) cutout is engaged with manual plate (2) projection.
- Install bolts (A), (B) and (C) in control valve with TCM. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. After that tighten them in order (1 ---> 2 ---> 3), and then tighten other bolts. Tighten control valve with TCM bolts to the specified torque.
<---: Vehicle front
^ Refer to the followings 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 [1][2]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
