The light came on about a month or so ago i took it in to get looked at but my mechanic could not find anything wrong. It has now come back on. Each time the light appears my car will not allow me to shift out of park. Today i turned it off let it sit for awhile and turned it back on after several times doing this it finally shifted out of park but the light remained on. I later tired again to leave and the light came back on and i can not shift again. HELP PLEASE!!
