How do you remove the gear shifter knob on a 2006 Lincoln navigator?

To remove the gear shifter knob on a 2006 Lincoln Navigator, first, ensure the vehicle is in the "Park" position. Locate the small plastic cover at the base of the shifter and gently pry it off to expose the retaining screw. Use a screwdriver to remove the screw, then pull the shifter knob upwards to detach it from the shifter assembly. Be careful not to force it, as there may be clips that require gentle manipulation to release.
