I have a 08' chrysler sebring touring recently today the shifter was stuck on park it didnt want to move down to "R N D 3" anybody know whats causing the locking?

 

Non-specific answer here for your model, but in general the brake pedal must be depressed in order to unlock the shifter. My '97 Sebring takes a considerable depression. It could be a problem with that interlock, or you may just need to press a bit harder on the brake.

 

Sometimes, with a column shift, if the wheels are not straight, the steering wheel presses up against the shift lock and makes it impossible to shift out of Park. Merely turning the wheel a little bit can relieve the situation and allow the lever to shift.
