2009 Madza CX-9 will not shift out of park.
 

My car has been sitting for about 6 or 7 months. before it was shifting just fine and i parked it bc i needed to get a head gasket done just havent got to it. But for some reason it will not shift out of park anymore. even when i take off the Interlock it will still not shift out of park. Anyone know what is going on and what i need to fix it? the battery was dead but i jump it and it starts just fine. Break lights are working when i push the pedal.
