I'm no trans. expert but I do know they should be serviced regularly. You ask about preventative maintenance; how long has it been since the trans fluid and filter were changed? Most vehicle say when towing you should have it done every 25,000 to 30,000 miles. For your low mileage situation I would think time would be more of a factor. Either way I think it's time for a servicing at minimum.
