I have a 2003 230 coupe and noticed that after it sat nose up on an incline for a couple of days, that the transmission became very hard to shift into first and second gears. It didn't loosen up again until several days later. Does anyone know what might be the problem. The transmission shifting has loosened back up now, so the dealer can't find any problems. My thinking is that maybe the gear oil isn't getting circulated over the gears properly.
