Yeah, don't get me started on Dealerships...that's why I sought out the Indy in the first place. Our local MB dealer was the one who told me the 722.6 transmission could not be serviced and that is was "sealed for life and you could not change the fluid or filter in it without taking it completely apart which would be very costly" (their words, not mine)! After that I decided paying them for their "expertise" was not going to happen
