Buy Actoss The Counter
Brother of The Benz, gebhard
Don't throw money out the window.
RedLine Transmission Fluid has no magic in it; it can't fix that which be brokey.
If you want to change the fluid, use the standard fluid recommended for your unit and see wha hoppens.
Just because you don't like the Benz service department, you can still purchase a transmission across the counter and have it installed buy some else and still benefit from all of the plus features offered by M/B.
Think it over!
