Based on the year model , I would expect that the vehicle is high mileage. In some cases, when the fluid is changed after high miles, it washes out particulates that help keep the fluid in the right places.
From my research on transmission changes, I believe that you must use Mercedes fluids. A measured quantity is removed and replaced with the same amount and brand. Then a thermal heat gun is used to make sure the temperature of the fluid is correct.
I expect that you are headed for a transmission rebuild or replacement.
