Hi, the symptom you are describing would indicate a faulty electronic gearshift selector module. When the module malfunctions the transmission will default to limp home mode and you will not be able to move the shifter into park without turning the key off. A diagnostic scan should be performed to confirm the fault but a faulty gearshift module is usually the problem.Let me know if you have any questions.Marty
