I just bought 2008 S550 4matic. It has 87K miles. According to manual, transmission oil supposed be changed on 39,000 miles, but was never changed. Car is running fine and does not have any problem. I was told that if running fine - do not change, because it sometime can cause more problem to transmission. Do you have any recommendation, good or bad experience after transmission oil change.
