Can I unseize my van? on 2001 Chrysler Town & Country

I heard a bomb like I hit something driving down the freeway. I pulled over to the far lane thinking my van was about to die. It went another 2 miles on the freeway and then I got off stopped at the turn light and it took off fine. I parked the van for about 4 hours went out to leave, it started, went in to gear fine but wouldn't move. Is it seized? Can it be unseized?

I will need a little more info such as if you notice any leaks on the ground and check your transmission fluid then check if you got a seized brake caliper
