On my 2000 expedition it was a loose bolt. this bolt aligns the gear shifter with the transmission position. it is located under the dash, just follow the column, it will be on top of the column with a torx bolt (i believe it was a torx) anyways if you jiggle the gear shifter while looking up you will see where they connect together with a bracket with the culprit bolt.
Note, make sure you use some locktite or you will have the same problem over and over again.
sorry if this seems a little vage, it's late and just seen this question ;)
It means you turned it off, usually a little button on the end of the shifter.
