Transmission Speed Sensor: Service and Repair

Revolution Sensor Components

Image Symbols:

REMOVAL
1. Disconnect the battery cable from the negative terminal.
2. Drain ATF through drain plug.
3. Remove front cross bar.
4. Remove exhaust front tube and center muffler with power tool. Refer to EX-3, "Components". Service and Repair
5. Remove rear propeller shaft.
6. Remove control rod.





7. Remove oil pan and oil pan gasket.





8. 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 AT-15, A/T Fluid Cooler Cleaning". A/T Fluid Cooler Cleaning
9. Support A/T assembly with a transmission jack.

CAUTION: When setting transmission jack, place wooden blocks to prevent from damaging control valve with TCM and transmission case.

10. Remove rear engine mounting member with power tool.





11. Remove tightening bolts for rear extension assembly and transmission case.





12. Tap rear extension assembly with soft hammer.





13. Remove rear extension assembly from transmission case. (With needle bearing.)





14. Disconnect revolution sensor connector.

CAUTION: Be careful not to damage connector





15. Straighten terminal clip to free revolution sensor harness.





16. Remove revolution sensor from transmission case.

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.

INSTALLATION

CAUTION: After completing installation, check A/T position, A/T fluid leakage and A/F fluid level.





1. Install revolution sensor in transmission case, and then tighten revolution sensor mounting bolt to the specified torque. Refer to AT-259, "COMPONENTS".

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.





2. Connect revolution sensor connector.





3. Securely fasten revolution sensor harness with clip.





4. Apply recommended sealant (Genuine Anaerobic Liquid Gasket or equivalent.

CAUTION: Completely remove all moisture, oil and old sealant, etc. from transmission case and rear extension assembly mounting surfaces.





5. Install rear extension assembly to transmission case. (With needle bearing.)

CAUTION: Insert the tip of parking rod between the parking pole and the parking actuator support when assembling the rear extension assembly.





6. Tighten rear extension assembly mounting bolts to specified torque. Refer to AT-259, "COMPONENTS".

CAUTION: Do not reuse self-sealing bolts.

7. Install rear engine mounting member.
8. Install oil pan to transmission case.
a. Install oil pan gasket to oil pan.

CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan mounting surface.





b. Install oil pan (with oil pan gasket) to transmission case.

CAUTION:
^ Install it so that drain plug 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.





c. Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them. Refer to AT-259, "COMPONENTS".

CAUTION: Do not reuse oil pan mounting bolts.

9. Install drain plug to oil pan, and then tighten drain plug to the specified torque. Refer to AT-259, "COMPONENTS".

CAUTION: Do not reuse drain plug gasket.

10. Install control rod.
11. Install rear propeller shaft.
12. Install exhaust front tube and center muffler. Refer to EX-3, "Components". Service and Repair
13. Install front cross bar.
14. Pour ATF into A/T assembly.
15. Connect the battery cable to the negative terminal.
