I have an 04 325 600 with a six speed - I have noticed that over about 4000 miles my shift knob has made 2 full clockwise revolutions - does anyone know what causes this and has any one experienced this before. I would have assumed that it would go counter clockwise if it was coming loose. I cannot turn it back the other way from in the cab. I dont think that this is an indicator of anything wrong but if any one knows let me know - thanks - Jneighbors
