8. 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

CAUTION: Do not reuse oil pan mounting bolts.

9. Install drain plug to oil pan. Tighten drain plug to the specified torque.

CAUTION: Do not reuse drain plug gasket.





10. Install bracket (2) to transmission assembly.
<=: Vehicle front
<=: Bolt
11. Install heated oxygen sensor 2 harness (B). to clips (1).
12. Connect heated oxygen sensor 2 harness connector (A).
13. Install exhaust mounting bracket.
14. Pour ATF into A/T assembly.
15. Connect the battery cable to the negative terminal.

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. Service and Repair

INSPECTION AFTER INSTALLATION
After completing installation, check for A/T fluid leakage and A/T fluid level.
