13. Remove the main control transaxle separator plate.






14. Remove the 2 bolts and separate the solenoid body from the main control valve body.

Installation





1. Install the solenoid body onto the main control valve body. Install the 2 bolts.

- Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.






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






3. Install the main control.

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






4. Install the main control and the nut and 22 bolts.

- Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.

CAUTION:Make sure not to pinch the OSS or TR sensor wiring harnesses when installing the main control.
NOTE:Install the different length bolts in the locations noted during disassembly.






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






6. Connect the TR sensor electrical connector.






7. Install the main control cover grommet.






8. Clean the main control cover sealing surface.






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






10. Position the main control cover in place.






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

- Tighten to 12 Nm {1.2 kgf-m, 106 in-lbf}.

CAUTION: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 transaxle fluid leak will occur.
NOTE:Install the stud bolts in the locations noted during disassembly.






12. Position the transaxle fluid cooler tube bracket and transaxle fluid cooler tube assembly in place and install the 2 nuts.

- Tighten to 9 Nm {0.9 kgf-m, 80 in-lbf}.






13. Connect the transaxle electrical connector.






14. Connect the selector lever cable end to the manual control lever with the manual control lever and selector lever in DRIVE. Check selector lever cable adjustment. See Adjustments.






15. Install the ACL assembly.
a. Install the ACL assembly bracket bolt.
i. Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.

b. Connect the MAF sensor electrical connector.

c. Connect the brake booster vacuum hose to the ACL outlet pipe.

d. Attach the wiring harness fastener to the ACL assembly.

e. Connect the engine breather to the ACL assembly.

f. Tighten the ACL outlet pipe clamp at the TB.
i. Tighten to 5 Nm {0.5 kgf-m, 44 in-lbf}.

16. Fill with clean transaxle fluid to the correct level.

17. Download a new solenoid body strategy to the PCM. See Description and Operation.

18. Using the scan tool, select module programming and programmable parameters under the tool box icon and select transmission. Follow the instructions displayed on the scan tool.
There are fields to enter the solenoid body 7-digit identification and 13-digit strategy recorded from the solenoid body.

19. The scan tool will verify that the numbers entered are valid and display a message if the information is not valid.
The scan tool checks to see if the file is present on the scan tool. If the file is present, the technician may proceed with downloading the file to the PCM. If the file is not present, the scan tool will need to be connected to the PTS server to download the file onto the scan tool.

20. Verify that the file is present on the scan tool. If the file is present, go to Step 8. If the file is not present, continue with this procedure.

21. Connect the scan tool to the PTS sever.
The screen will display a progress bar when connecting to the network.

22. Follow the instructions on the network to download the strategy file to the scan tool.
The screen will display a progress bar when downloading the strategy file to the scan tool and display a message if it is downloaded successfully.

23. If the scan tool cannot be connected to the Professional Technician Society server, contact the National Hotline.

NOTE:If the scan tool cannot download a strategy from the web site, a partial strategy will automatically be downloaded.
24. Reconnect the scan tool to the vehicle.






25. Install the solenoid body onto the main control valve body. Install the 2 bolts.

- Tighten to 10 Nm {1.0 kgf-m, 89 in-lbf}.

26. If a new solenoid body was installed, compare the 7-digit identification and the 13-digit strategy fields from the solenoid body to the replacement solenoid body tag provided with the solenoid body service kit and place it over the existing identification tag.
The scan tool will automatically download the strategy file or partial strategy file to the PCM and will display a progress bar while downloading. The scan tool will display a message when it is finished downloading the data that states that the file was downloaded successfully.
