You should have your local repair shop perform a full diagnostic of your Automatic Transmission system. Does it have the proper fluid level? There is a cable called shift/cable that needs to be inspected for proper adjustment. Has the Transmission filter been replaced or serviced? in some cases the use of a scan tool must be used to properly Diagnose a Transmission problem.
