Repair Procedure

1. Using a Hi-Scan Pro, check for codes in the "Automatic Transaxle and "Engine" menus. Record the DTC and description.

2. Clean the connection between the battery cables and the battery posts.





3. Clean the connection between the negative battery cable and the transaxle case. Reinstall the cable.

NOTE:
This procedure is necessary because the solenoids ground through the transaxle case and negative battery cable.

NOTE:
A high resistance ground usually causes two or more DCCSV or [1][2]PCSV DTC (P0742, P0743, P0745, P0747, P0748 or P0765).





4. Clean the connection between the negative battery cable and the body ground bolt located next to the battery. Apply conductive grease to the connection before reinstalling the bolt.

NOTE:
This procedure is necessary because the TCM grounds through the body ground.

5. Measure the voltage drop between the negative battery cable and the transaxle case:

^ Start the engine and turn on the headlights.





^ Use a digital voltmeter to measure the voltage drop between the negative battery terminal and the transaxle case (use VDC setting). If the voltage drop is as shown.

6. Disconnect the connectors at the solenoids and TCM. Check for bent pins or pins not fully inserted in the connector. Repair as necessary.

NOTE:
Clean connector pins with a contact cleaner listed below, or equivalent:

^ NAPA Electronic Cleaner, P/N 765-1843

^ MOPAR MP-50 Electrical Contact Cleaner, P/N 04549626

^ Permatex Electrical Contact Cleaner, P/N 24379 or equivalent.





7. Refer to the DTC recorded in Step 1. To correct the DTC, perform the related repair shown.

SOLENOID ASSEMBLY REPLACEMENT:





8. Using a screwdriver, remove the clip and push the solenoid connector into the transaxle case. (On earlier models, use two screwdrivers to push the tabs of the solenoid connector inward, then push the connector into the transaxle case).





9. Remove the oil temperature sensor from the bracket. Remove the oil filter. Remove ten 10 mm bolts and remove the valve body.





10. Remove the solenoids and carefully reinstall the new solenoids in the same location. Tighten the bolts to 3-4 lb-ft (40-60 kg.cm).





11. Confirm the 0-ring is installed on the top center of the valve body and the valve body pipe is installed on the top of the valve body.





12. Carefully align the manual valve on the valve body to the manual control shaft and reinstall the valve body. Install the bolts and torque to 7-9 lb.ft (100-120 kg.cm).

13. Reinstall the temperature sensor to the bracket.

14. Push the solenoid connector through the hole in the case. Reinstall the clip on the solenoid connector.

15. Reinstall the oil filter and tighten the bolts to 4-5 lb.ft (50-70 kg.cm).

16. Install a new pan gasket and reinstall the oil pan. Tighten the bolts to 7-9 lb.ft (100-120 kg.cm).

17. Add SPIII ATF (approximately 4-1/2 quarts for Accent, 5 quarts for Elantra/Tiburon) and check the level with the engine idling in Neutral. Confirm the ATF is at the correct level when the ATF is at normal operating temperature (70-100°C, 159-212°F).





18. 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 upshifts and 4-3-2-1 downshifts). If the DTCs return, perform the repairs shown.
