general problems of the 1999 Ford Windstar

The vehicle when parked at any degree of incline or decline has had repeated tendencies not to shift out of park. On this occasion, I had the vehicle on ramps changing my oil and went to put it in neutral to level it out. The vehicle appeared to have gotten stuck in reverse and neither the foot brake nor the emergency brake would stop it. It would not let me shift into any of gear until it reached level ground. I had an appointment with the dealer to look at the transmission on may 31, 2007 because I had been having trouble with the transmission shifting very rough and feeling a jerking sensation when I shifted from park to either drive or reverse.
