The transmission shifter/column is stuck.
Evaluate your brake light operation. When you press on the brake pedal, the lights should come on and disengage the shifter solenoid (which allows you to shift out of gear). You may have a brake switch, shift solenoid, or wiring problem which may cause this issue. A qualified technician, such as one from YourMechanic, can assist you with diagnosis and repair of your vehicle.
