1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer have metal debris or excessive clutch material?
YES – Replace the transmission.
NO – Replace the ATF, then go to step 4.
4. Turn the ignition switch ON (II).
5. Clear the DTC with the HDS.
6. Choose Lockup Solenoid Test in Miscellaneous Test Menu, and check that the torque converter clutch solenoid valve operates with the HDS.
Is a clicking sound heard?
YES – Go to step 7.
NO – Replace the torque converter clutch solenoid valve, then go to step 11.
7. Choose Clutch Pressure Control (Linear) Solenoid C in Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
Is the result NORMAL?
YES – Go to step 8.
NO – Follow the instructions indicated on the HDS by the test result, but the tester has not determined the cause of the failure, go to step 11. If any part was replaced, go to step 12.
8. Run the engine until the ECT SENSOR value reaches 176°F (80°C).
9. Test-drive the vehicle at 55 mph (88 km/h) for 2 minutes while monitoring the vehicle speed with the HDS.
10. Monitor the OBD STATUS for P0741 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

NO – Intermittent failure, the system is OK at this time. If the screen indicates NOT COMPLETED, go to step 9.
11. Inspect A/T clutch pressure control solenoid valve C.
Does A/T clutch pressure control solenoid valve C work properly?
YES – Repair the hydraulic system related with the lock-up shift valve, the lock-up control valve, and the lock-up timing valve, or replace the transmission, then go to step 12.
NO – Replace the A/T clutch pressure control solenoid valve C, then go to step 12.
12. Turn the ignition switch ON (II).
13. Clear the DTC with the HDS.
14. Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
15. Check for DTCs with the HDS.
Is DTC P0741 indicated?
YES – Go to step 7.
NO – Go to step 16.
16. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
