More than likely, it is letting you know there is a problem. It may not be readily noticeable by driving. With that message, it will have set a code in the ECM. This would direct you in a diagnostic path. If I had to take a guess, with no complaint of hard/firm shifts, it is an input speed or torque converter related fault. Both are relatively spendy repairs, requiring some degree of transmission disassembly.
