Mercedes-Benz C200 2009: Topping up transmission fluid?
If it has a dipstick it can, but you'll find your car doesn't. Automatic transmissions these days are so-called "filled for life", which means they're filled with fluid at the factory and there should be no need to regular checks or top-ups. If you want to change the fluid, which can be a good idea, you need to go to an auto trans specialist.
Mercedes-Benz C200 2008: Kompressor auto transmission problem
Your frustration is understandable. I would urge you to go back to Mercedes-Benz direct and request some assistance with the cost of repairs. While I doubt that Mercedes would cover the whole cost of the job, I would think they might cover part of the cost if you approach them in a reasonable way. If you don't want to go down that path consult an automatic transmission specialist and get another quote for repairs.
