I believe it works the same way the stick shift does. The operator lever when pulled back moves the long moving inner rod down against the spring. I believe the shift tube has a slot in it and the detent lever has a pin which fits thru the slot in the shift tube and captures the moving rod by the pin passing thru a hole in the end of the rod.

As the rod moves down it moves the detent lever down 1/4" or so along the splines and away from the detent plate so the small pin on the end of the detent lever can clear some interference in the plate. Once the operator lever is pulled so rod can move down it pushes the detent kever along the splines and by moving the operator lever up or down and pin clear, it will move the detent lever out of park or reverse position. The linkage lever at the very bottom is clamped to the splines too so it will move with the shift tube but I believe there should be a space large enough for the detent lever to move down on the splines and clear the plate.

The upper detent plate is not fastened to the shift tube but rather is attached to the steering column tube and is fixed by a U clamp. It just provides a bearing for the shift tube passing thru it. Not knowing exactly what position the operator lever is in, possibly It could be that the detent plate is clamped too far down or it could be the linkage lever is too far up. Either would lessen the clearance and prevent the detent lever from moving away from the plate.

I did not look to see what Packard called the various pieces so here is an illustration labeled with what I am calling the parts in the narrative.
