It should only rock back and forth a few inches, if it moves (ft.) either the linkage is damaged/out of adjustment or the parking pawl inside is damaged.
Recreate the slope please. otherwise it won't be able to park. or may be try to park it on petrol mode.
your car will not be able to move sees the shaft is broke.
yes, if it isn't in park and is on an incline it surely can
The transmission is not in park and/or the parking brake is not applied.
Press the brake before you move it out of park
the new cars gear will not move unless the car is running
not using park brake is usually the problem for this try setting park brake before you take foot off brake when you park, so as vehicle does not move try using park(emergency) brake before you put car in park
You park in the basement car park.
Some vehicles have a safety switch that keeps you from shifting out of park if the brake isn't on. If that switch has failed or is adjusted improperly you will not be able to get out of park. CALL THE REBUILDER AND POLITELY ASK HIM TO FIND OUT WHAT IS WRONG.
Ask them to move, and if they don't then call a tow truck.
in a car park
Question: Is the car running or stalled? If stalled try starting it. If the key won't turn to start it or move to another position, try to move your steering wheel out of the locked position. Somtimes when there is resistance, or pressure against the lock you will not be able to turn the key - on or off. Question: Are you stopped on an incline? If so, the gear may not allow you to move to park (or out of park sometimes) if there is positive resistance on the transmission. This would prevent you from putting in park.
