I can think of two possibilities, one is the shift interlock, the other is the shift linkage. If you get under the vehicle and take the shift linkage loose from tranny, can you shift the tranny by hand, into park, using the shift lever on the side of the tranny. There are safety issues with that, safety is your responsibility. Level ground-- wheels blocked-- functional parking brake is set. Yes, you will have to safely raise and support the vehicle.
