My 2001 ford Taurus locks in park position occationally?

Use the parking brake so the vehicle doesn't roll on incline(slight) and put pressure on the park pawl in the transmission… We had a couple hundred of these. Even though it happens on most vehicles the Taurus got lots of complaints for it… My personal Tauruses, I used the parking brake. They'd roll on any surface a couple inches and make shifting hard…
