Cadillac deville: P0741 Torque Converter Clutch Circuit Performance

This answer was rated:

P0741 Torque Converter Clutch Circuit Performance or Stuck Off
01 cadilac deville

Hello I will help you with youre question,


The engine computer looks for a change in the slip speed of the torque converter when it applies the torque converter clutch through its oil control solenoid in the transmission. If this change in slip does not take place it flags this code.


The likely cause of the failure to apply the TCC is the solenoid or its wiring harness has shorted or opened so that the solenoid does not move when commanded. This is very common with this transmission.


The repair is to remove the side of the transmission and replace the TCC solenoid and inspect the wiring harness. The solenoid is about $50 but it takes 8 hours of labor to replace it.


Please let me know if you have further questions about this


Thank you
