My Cadillac keeps going into PARK Shift won’t shut off

Hello, sounds like a concern with the shift lever position sensor, which tells what gear the shift lever is shifted into. A diagnostic tool can monitor the shift lever position as you move it through the selections to see how it reads and then lead to troubleshooting if you have a sensor, shift lever or wiring concern.
