I tried to find the procedure for aligning your shifter, but could not find a link I liked. I would try the shifter alignment first as there are I believe three screws which hold the assemble in place and have been known to loosen and allow the shifter to move. I believe you loosen the screws, Torq's possibly put in an alignment pin which should be with the shifter arm somewhere and then torque the screws back down.
I think you have to remove your center console to do this procedure
I cannot find where I read it
Maybe someone else knows of a link with instructions and photos.
