PARTS INFORMATION:





WARRANTY INFORMATION:

SERVICE PROCEDURE:

1. Using a GDS, check for DTC in the "Automatic Transaxle" menu. Record the DTC and description. Delete the DTC.

2. From the GDS, select the following parameters.

^ Vehicle and A/T menu.

^ "Actuation Test"





Press the "Start" button and look for a "Success" indication.

3. If the test results show:

^ "Success" - The GDS requested the TCM to activate the solenoids. Use chassis ears or stethoscope to listen for solenoid operation. If the solenoids are audible, the harness currently has no open/short circuit. Go to Step 5.

^ "Failure" - The GDS did not request the TCM to activate the solenoids. Click on the "Retry" button on the top right of the screen. If "Failure" is displayed again, go to Step 4.

4. Visually check the wiring harness between the PCM and transmission for a damaged wire or short circuit to ground. Check for a damaged pin or pin not fully inserted into the connector.

^ If damage exists, repair or replace the ECM control harness and drive the vehicle to confirm the repair.

^ If not, go to Step 5.





5. Refer to the DTC recorded in Step 1 and follow the repair procedure shown:

6. Record the radio stations. Remove the battery and battery tray.

7. Remove the undercover below the transmission.

8. Drain the radiator and remove the lower radiator hose from the radiator, if necessary. Drain the ATF.





9. Use a screwdriver to release the tab and remove the solenoid connector on top of the case.

Remove the bolt that secures the connector and push the connector into the transmission.

Disconnect the vent hose on the top of the oil pan.





10. Remove the oil pan bolts and remove the pan.





11. Use a small screwdriver to pry the connector from the oil temperature sensor.





12. Remove three bolts to the solenoid valve connector.





13. Pull the solenoid connector outward and move the connector out of position.





14. Remove the bolt that secures the detent spring and remove the spring.

Torque: 8~11 lb.ft (1.2~1.6 kgf.m)





15. Remove the valve body bolts in the order shown and remove the valve body.





16. Use a screwdriver to depress the locking tab and pull outward on the connector to the input and output speed sensor.





17. Remove two bolts that secure the valve body harness to the case.

Pull the connector downward out of the case.

Install a new harness and insert the connector into the case. Attach the retainer and bolt on top of the case as shown in Step 9.

Install the bolts that secure the harness. Torque: 7~9 lb.ft (1.0~1.0 kgf.m)





18. Use a 5mm hex socket and remove 9 Allen bolts that secure the solenoid support. Remove the solenoid support.





19. Refer to the DTC recorded in Step 1 and replace the related solenoid





20. Confirm the O-rings are installed correctly in the case.

Reconnect the input and output speed sensor connector to the harness.





21. Align the manual shaft to the shift lever and install the valve body.





22. Install the valve body bolts and torque the bolts to specification in the order shown.

Toque: 7~9 lb.ft (1.0~1.2 kgf.m)

23. Reconnect the solenoid harness to the solenoids and oil temperature sensor.





Install the bolts to the solenoid harness connector and torque to specification.

Torque: 7~9 lb.ft (1.0~1.2 kgf.m)





24. STEEL OIL PAN:
Apply Permatex Ultra Gray Sealer or Hyundai Ultra Gray Gasket Sealer, P/N 00232-19039, to the oil pan and reinstall the pan.

PLASTIC OIL PAN:
Install a new gasket to the oil pan and reinstall the pan.

Tighten the bolts to specification.

Torque: 10~12 lb.ft (1.4~1.6 kgf.m)

25. Add ethylene glycol engine coolant to the radiator and check the level according to the appropriate shop manual, "Engine" Section.

26. Reconnect the battery.
Input the radio stations recorded in Step 6.





27. Remove the transaxle fill plug.

Use a funnel to add approximately 5~6 quarts of SPH-IV ATF through the fill plug opening. Reinstall the fill plug.

Attach the GDS to the DLC and select vehicle A/T menu Current Data and "Oil Temperature Sensor".

Start the engine and shift to Park. When the ATF is 122°F~140°F (50~60°C) remove the level checking plug. The level is correct when oil flows out of the level checking plug in a thin steady stream.

Collect and dispose of any excess fluid in accordance with local regulations.





28. Clear the codes and test drive the vehicle for two driving cycles (two key-on to key-off driving cycles, including 1-2-3-4-5-6 upshifts and 6- 5-4-3-2-1 downshifts). If the DTC returns, perform the following repairs

29. Drive the vehicle to confirm the transmission is operating as designed.
