I just spent some time in the books. I expect the shifter will need to be lifted out. A bit time consuming but not bad to get to.

This Tcase has two parallel fingers coming up and forwards into the top cover of the case that the shifter engages. It in some ways is a simpler shifter than on the manual trans models.
In the automatic the spring that returns the shifer to the center of the vehicle is up in the shift extension rather than down in the shift rails as in a Xfer behind a manual.

On a manual the whole top cover must be lifted to inspect the shifting but an auto just the shifter needs to be lifted for initial inspection.
I have a gut feeling some damage was done but the first thing is to get a look in from the top and see if the fingers are intact and still close together.

One question, can you determine if the truck is in 2WD or 4WD? presuming the tcase is in neutral, it should also be in 4WD. It may be possible the 2-4 rail got kicked back into 2WD. If this is the case the forks do not line up so the shifter will not function.

What also may need to be determined, Did a shift fork bend? probably not.
Did a roll pin get sheared off in a rail? This can and does happen.
Did one of the fingers in the case bend or break? I have no clue if that can or does happen.
I do know one thing though, women, especially smaller ones can break things strong men can't.
