Hello Wayne:

Do you have your service manual handy? Take a look in there, and it will list the type of transmission fluid that you need.

I don't know if your car has this or not, but my 190e has a little sticker on the metal part immediately above the cooling fans that list the type of fluid as well. When you open up the hood, the sticker should be right there.

Hope this is helpful.

Thanks,
Michael.

Wayne, ATF does stand for Automatic Transmission Fluid. Believe it or not MB does not list any synthetic tranny fluid as an approved fluid for thier transmissions. I have a copy of MB's "Factory Approved Service Products" and it has a long list of approved tranny fluids. To my surprise, Mobil is not one of them. The approved ATF fluids are; Castrol Dextron III/Mercon, Castrol Transmax, Chevron ATF Dextron III, Citgo Multi-purpose ATF, Exxon Superflo ATF Dextron III, Havoline ATF Mercon/Dextron III, Texaco ATF Mercon/Dextron III, Pennzoil ATF, Quaker State Dextron III/Mercon, Sunoco ATF Dextron III/Mercon, Unocal Multi-Purpose ATF, and finally Valvoline ATF Type D. This list is as of Nov. 2001. As you can see there is a wide variety of brands to choice from. FYI "Dextron" is a standard created by GM and "Mercon" is a Ford standard. Most cars on the raod require Dextron grade tranny fluid. As you can see from the list above, none of them are synthetic.
