If the gear select lever is stuck in PARK, the problem is the brake interlock inside the steering column is locking it there.
Common cause of this is the Brake ON / OFF Switch (BOO) which is mounted to the brake pedal shaft up under the dashboard.
One of the wires can break off, or the switch can be defective.
To shift out of Park, you MUST be pushing the brake pedal down while moving the gear select lever, the interlock will be locked if it does not sense the brake pedal being pushed.

If you are stuck someplace......you can turn the motor OFF......shift into Neutral, start the motor and then shift into Drive.
HOWEVER, if the problem is caused by the brake ON/OFF switch or wire to it, you will ALSO have NO brake lights on the back of the vehicle, which is very dangerous.
Once you shift into PARK with the motor running, you will not be able to shift back out of it without shutting the motor off.....shift into Neutral, start the motor and select your gear.
The repair of the brake ON/OFF switch wire or replacement of the switch is easy to do.
