have problems with gear shift on 2004 thunderbird

What is your question?

when I put car in park sometimes can't shift out of park. Then again sometimes it just takes me wiggling the shifter and pushing button really hard to make it work, I've had to call for help a couple of times.

What makes this problem better or worse?

Sometimes when I first start the car to leave home, then sometimes just after I turn it off and crank it back up.

How long has your 2004 Ford Thunderbird had this problem?

It has happened a couple of times over the last 2-3 months
