Grinding Noise

Grinding Noise
Knowing the inexperience of a new driver my son (just got his license) was parked in our Montero. I was gonna let him drive home from the school and we swapped sides. He must have thought the ignition was still on and he shifted to reverse. Inadvertently, we started rolling backwards and he shifted back to park while the car was still moving but heard a terrible grinding noise. We didn't stop until we hit the curb. The car also hesitated to start after the ordeal but got it going again after a few minutes.
So my question is would this grinding cause damage or be of concern?

been doing some research and found this
How exactly could I check if anything was wrong? Should I take it to the shop immediately?
The pawl might also fail or break if the vehicle is pushed with sufficient force, if the parking brake is not firmly engaged. Replacement can be an expensive operation since it generally requires removing the transmission from the car. It is also not recommended to use the parking pawl to stop a vehicle in motion. The pawl mechanism is not strong enough to stop a vehicle in motion or may not engage at all. Under that much stress, the pawl may break off in the transmission, leading to costly repairs.

X2 what the prior poster said. Stop on a (really) slight rise, put it in park without the handbrake on and ease up on the brake pedal. If it starts to roll and/or makes the same grinding noise you've got pawl trouble. If not, then you should be fine.
But this may be important - I'm not sure if the pawl mechanism is inside the transmission case or at the flywheel. If it's inside the case (experts please jump in) then you should consider having the transmission fluid flushed to get rid of any metal shavings. It's not a bad idea to have it done anyway if the truck is high mileage. Mitsu dealers have a special flushing service for about $160. Not sure I'd trust the drive through folks.
