DTC Troubleshooting: P0741
DTC P0741: Torque Converter Clutch Circuit Performance or Stuck OFF
NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How To Troubleshoot A/T Systems
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 ATF Replacement 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, then go to step 12.
NO - Replace the ATF, ATF Replacement then go to step 4.
4. Clear the DTC with the HDS.
5. Select Shift Solenoid D in the Miscellaneous Test Menu, and check that shift solenoid valve D operates with the HDS.
Is a clicking sound heard?
YES - Go to step 6.
NO - Replace shift solenoid valve D, A/T Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement then go to step 11.
6. Run the engine until the engine coolant temperature reaches 176 °F (80 °C).
7. Select Clutch Pressure Control (Linear) Solenoid C in the Miscellaneous Test Menu, and test A/T clutch pressure control solenoid valve C with the HDS.
Does the HDS indicate NORMAL?
YES - Go to step 8.
NO - Follow the instructions indicated on the HDS by the test result, but if the HDS has not determined the cause of the failure, go to step 10. If any part is replaced, go to step 11.
8. Test-drive the vehicle on a level road with a steady throttle at 60 mph (96 km/h) for at least 22 seconds, or test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
9. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.
Does the HDS indicate FAILED?
YES - Repair the faulty torque converter clutch mechanism, torque converter clutch hydraulic circuit, lock-up shift valve, or lock-up control valve, or replace the transmission, then go to step 11.
NO - Intermittent failure, the system is OK at this time. If the HDS indicates NOT COMPLETED, return to step 8 and recheck.
10. Inspect A/T clutch pressure control solenoid valve C. A/T Clutch Pressure Control Solenoid Valve C Test
Does A/T clutch pressure control solenoid valve C work properly?
YES - Repair the hydraulic system related to the lock-up shift valve, lock-up control valve, and lock-up timing valve, or replace the transmission, then go to step 11.
NO - Replace A/T clutch pressure control solenoid valve C, A/T Clutch Pressure Control Solenoid Valve C Replacement then go to step 11.
11. Clear the DTC with the HDS.
12. Test-drive the vehicle on a level road with a steady throttle at 60 mph (96 km/h) for at least 22 seconds, or test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.
13. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES - Troubleshooting is complete.
NO - Return to step 5 and recheck. If the HDS indicates NOT COMPLETED, return to step 12 and recheck.
