If a rear drive vehicle, jacking up one rear wheel probably would not relieve pressure through the
differential. Usual fix is to push (jog) the vehicle against the direction of the jam to relieve
pressure; then take it out of park.

"The Kid" is closing on his house today. backing his van up a steep hill
with a heavy trailer, he put it in park and got out to make sure he wasn't
going to hit anything. Now, its stuck.

I leave in a bit over an hour to help him out and loan him a car if there's
not a quick fix.

He did jack up one rear wheel to relieve pressure, no joy.

Any quick ideas?
