Car will go into all positions except park. It will occasionally catch but for the most part will just roll. Must use emergency brake. How to I fix it. Have been parking on a hill, may have something to do with it.
Will not stay in park on 2001 Ford Expedition
Sounds like the parking pawl either needs adjustment or replacement. This is a 2 to 2 1/2 hour job and is usually done by a transmission shop.call some shops to see if they can handle this www.repairpal.com/directory
