2004 Lincoln Aviator Question: Gear wont shift
If your vehicle will not shift out of park, check to see if you have working brake lights. If not, your brake light switch may be failing, or its wiring connector. The switch handles release of the shifter interlock along with the brake light function. - DaveJHM
did once before. went into gear later. second time, this time wont turn over, shifter not locked in place can move freely with car off. is that normal.
