Wondering if a brake hose is collapsed. You would smell the brakes burning. Master cylinder will push fluid out but there is nothing to return it. Can you mess with the shifter to get any change? Any MIL on?
If the problem was a brake hose, it would still have been locked up when it was time to roll off the flatbed that hauled it home. He said it rolled off the flatbed without a problem.
Isn't there a switch that has to be activated when the brake pedal is pushed, before the brakes are leased when the trans is put in gear? Our 04 PT, you have to step on the brake pedal to allow the brakes to be released when the trans is put in drive or reverse. Could that switch could be bad?
