CAUTION:
^ Do not subject it to impact by dropping or hitting it.
^ Do not disassemble.
^ Do not allow metal filings, etc., to get on the sensor's front edge magnetic area.
^ Do not place in an area affected by magnetism.
^ Be careful not to damage harness with the edge of case.

INSTALLATION





1. Install revolution sensor in transmission assembly.

CAUTION:
^ Do not subject it to impact by dropping or hitting it.
^ Do not disassemble.
^ Do not allow metal filings, etc., to get on the sensor's front edge magnetic area.
^ Do not place in an area affected by magnetism.
^ Be careful not to damage harness with the edge of case.





2. Connect revolution sensor connector.
3. Securely fasten revolution sensor harness with terminal clip.





4. Apply recommended sealant (Genuine Anaerobic Liquid Gasket or equivalent. Refer to Recommended Chemical Products and Sealants.) to output shaft & companion flange complement as shown in illustration.

CAUTION: Complete remove all moisture, oil and old sealant, etc. From the transmission case and output shaft & companion flange complement mounting surfaces.





5. Install output shaft & companion flange complement in transmission assembly.





6. Tighten output shaft & companion flange complement mounting bolts to specified torque. (Because terminal bracket is tightened together with output shaft & companion flange, it should be installed before procedure 5.)

CAUTION: Do not reuse self-sealing bolt.

Output shaft & companion flange complement mounting bolt: 52 Nm (5.3 kg-m, 38 ft. lbs.)
Self-sealing bolt: 61 Nm (6.2 kg-m, 45 ft. lbs.)





7. Install engine rear member. Refer to Removal and Installation.
8. Install oil pan in transmission case according to the following procedures.
a. Install oil pan gasket on oil pan.

CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.





b. Install oil pan on transmission case.

CAUTION:
^ Install it so that drain plug comes to the position as shown in the figure.
^ Be careful not to pinch harnesses.





c. Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them.

CAUTION: Do not reuse oil pan mounting bolts.

Torque: 7.9 Nm (0.81 kg-m, 70 inch lbs.)
9. Install drain plug on oil pan.

CAUTION: Do not reuse drain plug gasket.

Torque: 34 Nm (3.5 kg-m, 25 ft. lbs.)
10. Connect heated oxygen sensor 2 harness connector.
11. Install propeller shaft. Refer to Removal and Installation.
12. Install exhaust front tube and center muffler with power tool. Refer to Removal and Installation.
13. Connect the negative battery terminal
14. Pour ATF into transmission assembly. Refer to A/T FLUID.
After completing installation, check fluid leakage and fluid level of transmission assembly. Refer to Checking A/T Fluid.
