P0741 CADILLAC - Torque Converter Clutch Circuit Performance or Stuck Off...Possible causes; Low transmission fluid level, Dirty transmission fluid, Faulty torque converter clutch solenoid valve, Torque converter clutch solenoid valve harness or connectors, Torque converter clutch solenoid valve circuit is open or shorted, Transmission internal mechanical problem......Watch this video.....


U1000 CADILLAC - Invalid or Missing Data for Primary Id... As with all loss of communication concerns, inspect the power, ground, and serial data circuits to the suspect module prior to replacing any parts...U10000 is set when the control module does not receive a message that it was expecting from another control module, and does not know which control module did not send that message.
