Welcome. These codes are for the torque converter clutch being stuck off. I have seen 2 possible causes for this. The first is a bad seal and the other is a bad solenoid. This will lower fuel economy and may eventually overheat the transmission depending on the driving style and load. You cannot turn the code off with out repairing it.

I GUESS THE REPAIR REQUIRES A COMPLETE TRANSMISSION OVERHAUL. THIS IS APROXIMATELY A $3000 OUTLAY -HARDLY WORTH IT ON A 2001 WITH 75,000 MILES. I ASSUME THE CADILLAC WARRANTY DOES NOT APPLY.

What is your VIN and I can check. As for the worth, These cars do last and I have seen these and done this repair at 150,000 miles so I guess that depends on what the car is worth. I would start with proper diagnosis. If it is the solenoid, you are looking at 800 or so. The engine and transmission come out very easily as a unit with the sub frame. I did one in 3 hours before, but that was only the solenoid.
