I have, as you can tell by all the posts, bought my wife a lovely 1999 SLK 230. I was going to change the Oil and filter in the gearbox as a matter of course when I get a different car, but it says in the hand book that it is permanent fill. Does this mean that you never have to change it? If you should change it then how often? and with what oil if you do. I have no reason to believe that there isn't enough oil, just that it is 10 years old. I take it that there is no way of checking the level?
