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. Drive the vehicle and monitor the sensors.
   • Vehicle and A/T menu.
   • "Current Data"
   • Input speed and output speed sensors.

3. If the sensors show:
   • Continuous and changing output with changes in vehicle speed, the wiring currently has no open/short circuits. Go to Step 5.
   • No continuous and changing output, 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 no damage, go to Step 5.
5. Refer to the DTC recorded in Step 1 and follow the repair procedure shown below:

   DTC	REPAIR PROCEDURE
   P0717-Input/Turbine Speed Sensor 'A' Circuit No Signal	Go to Step 6 and replace the input/output speed sensor and valve body harness.
   P0721-Output Speed Sensor Circuit Range/Performance
   P0722-Output Speed Sensor Circuit No Signal

6. 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. 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. [Image: Transmission solenoid connector with bolt indicated]
10. Remove the oil pan bolts and remove the pan. [Image: Transmission oil pan with bolts indicated]

    CAUTION: Use rubber hammer to tap the oil pan cover on a corner until the cover is loose.

11. Use a small screwdriver to pry the connector from the oil temperature sensor (except for vehicles with integrated temperature sensor and harness). [Image: Screwdriver used to disconnect sensor from transmission]
12. Remove three bolts to the solenoid valve connector. [Image: Solenoid valve connector with bolts indicated]
13. Pull the solenoid connector outward and move the connector out of position. [Image: Solenoid connector being pulled out]
14. Remove the bolt that secures the detent spring and remove the spring. Torque: 8~11 lb.ft (1.2~1.6 kgf.m) [Image: Detent spring bolt indicated]
15. Remove 8 bolts in the order shown and remove the valve body. [Image: Valve body with numbered bolts indicated]
16. Use a screwdriver to depress the locking tab and pull outward on the connector to the input and output speed sensor. [Image: Input and output speed sensor connector with locking tab indicated]
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: 6~7 lb.ft (0.9~1.0 kgf.m) [Image: Valve body harness bolts indicated]
18. Remove two bolts that secure the input and output speed sensor and remove the sensor. Install a new input/output speed sensor in the reverse order of assembly and tighten the bolts to specification. Torque: 6~7 lb.ft (0.9~1.0 kgf.m) [Image: Input and output speed sensor with bolts indicated]
19. Confirm the O-rings are installed correctly in the case. Reconnect the input and output speed sensor connector to the harness. [Image: O-rings in transmission case]
20. Align the manual shaft to the shift lever and install the valve body. [Image: Manual shaft alignment for valve body installation]
21. Install the valve body bolts and torque the bolts to specification in the order shown. Torque: 6~7 lb.ft (0.9~1.0 kgf.m) [Image: Valve body with numbered bolts indicated for torqueing]
22. Reconnect the solenoid harness to the solenoids and oil temperature sensor. Install the bolts to the solenoid harness connector and torque to specification. Torque: 6~7 lb.ft (0.9~1.0 kgf.m) [Image: Solenoid harness connector bolts indicated]
23. 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: 6~7 lb.ft (0.9~1.0 kgf.m)
24. 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.

25. Clear the codes and test drive the vehicle for two drive cycles (two key-on to key-off driving cycles).
26. If the DTC return, perform the following repairs:

    DTC	REPAIR PROCEDURE
    P0717-Input/Turbine Speed Sensor 'A' Circuit No Signal	Repair or replace the control harness between the PCM and the transmission.
    P0721-Output Speed Sensor Circuit Range/Performance	Test drive the vehicle for two drive cycles. If the DTC return again, replace the PCM.
    P0722-Output Speed Sensor Circuit No Signal

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