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.

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

Install the main control stud nut and 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 seal is on the inside of the main control cover or a transmission fluid leak will occur.

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

Install 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 electrical wiring harness retainers to the main control cover studbolts.





14. Connect the transaxle electrical connector.





15. Install the underbody cover and the screws.





16. Install the ACL assembly. For additional information, refer to Intake Air Distribution and Filtering - Air Cleaner.

17. Fill the transaxle with clean transmission fluid.





18. Start the engine and move the range selector lever into each gear position.

19. 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.
