Gilly,
You mentioned in a previous post that MB wants a few things done in the 722.6 trans if a tech goes into it for any reason. I, like a lot of other nervous ML owners, am considering a trans fluid change about the 55-60K mile point and was wondering what the "things" might be. Is there a filter involved (I would think not with liftime fluid)? Is the fluid change done with a suck and fill thru the dipstick or does a plate or pan have to be pulled off exposing tranny innards and then be resealed? Do the "things" to be done items consist of just adjustments or are upgraded parts also involved (will I have to pay for them or is this a tech bulletin?)? Lastly, is this job something I should ask for my shop's Master Tech to perform, or can any of my dealer's techs handle it?
