torque converter performance circuite stuck or off. on 2003 Cadillac Seville

03 4.6L Recieving a torque converter performance circuit off or stuck. Error is cleared and comes back maybe once every month. NO drivability or performance changes or issues what so ever. The car runs and drives great. I need to repalce the crank sensors with the updated modules but I don't think this ties into it at all? BUT I may be wrong. Any ideas I appreciate the help.Thanks.
