Output Shaft Speed (OSS) Sensor





Removal

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

2. Remove the retainers and the LH splash shield.





3. Remove the transmission fluid drain plug and allow the transmission fluid to drain.





4. Install the transmission fluid drain plug.
- Tighten to 12 Nm (106 lb-in).





5. Disconnect the transaxle vehicle harness electrical connector.





6. Remove the transaxle electrical wiring harness retainers from the transmission fluid pan stud bolts.





7. Remove the 2 nuts, pull the transmission fluid cooler tube bracket and tubes away from the transaxle and position it aside.





8. NOTE: Note the location of the stud bolts for assembly.

Remove the 8 bolts, 5 stud bolts and the main control cover.





9. Disconnect the Transmission Range (TR) sensor electrical connector.





10. Disconnect the Output Shaft Speed (OSS) sensor electrical connector.





11. Remove the main control-to-main control cover grommet.





12. NOTICE: The main control should be handled with care, damage to the main control may occur.

NOTE: Note the location of the different length bolts for assembly.

Remove the nut, 22 bolts and the main control.





13. Remove the main control-to-transaxle separator plate.





14. Remove the bolt and the OSS sensor.





Installation

1. Install the OSS sensor and the bolt.
- Tighten to 10 Nm (89 lb-in).





2. NOTE: If cleaning the main control assembly or inspecting the valves, refer to Main Control Valve Body Main Control Valve Body. If installing a new main control assembly, continue with this procedure.

Position the OSS and TR sensor wiring harnesses aside and install the main control-to-transaxle separator plate.





3. NOTE: Make sure that the manual lever pin (part of the TR sensor) is correctly installed in the manual valve.

Install the main control.





4. NOTICE: Make sure not to pinch the Output Shaft Speed (OSS) or Transmission Range (TR) sensor wiring harnesses when installing the main control or damage to the sensors can occur.

NOTE: Install the different length bolts in the locations noted during disassembly.

Install the main control valve body, the main control valve body nut and the 22 main control valve body bolts. Tighten in a crisscross pattern.

- Tighten to 10 Nm (89 lb-in).





5. Route the OSS sensor wiring harness and connect the electrical connector.





6. Connect the TR sensor electrical connector.





7. Install the main control-to-main control cover grommet.





8. Clean the main control cover sealing surface and inspect for damage.





9. Apply silicone to the main control sealing surface of the transaxle case.





10. Position the main control cover in place.





11. NOTICE: Inspect the main control-to-main control cover grommet to make sure that the seals is on the inside of the main control cover. Transmission fluid leak will occur.

NOTE: Install the stud bolts in the locations noted during disassembly.

Tighten the 8 main control cover bolts and 5 stud bolts.

- Tighten to 12 Nm (106 lb-in).





12. Position the transmission fluid cooler tube bracket and transmission fluid cooler tube assembly in place and install the 2 nuts.
- Tighten to 9 Nm (80 lb-in).





13. Connect the transaxle vehicle harness electrical connector.





14. Connect the transaxle electrical wiring harness retainers to the transmission fluid pan stud bolts.





15. Install the LH splash shield and the retainers.





16. Fill the transaxle with clean transmission fluid.

17. Using the scan tool with the engine running, check and make sure that the transmission is at normal operating temperature 85-93°C (185-200°F). Check and adjust the transmission fluid level and check for any leaks. If transmission fluid is needed, add transmission fluid in increments of 0.24L (0.5 pt) until the correct level is achieved.
