Thanks to the Forum, at least I'm an educated consumer. Took mine to the local dealership, and after pretty much explaining the step by step procedure to them, they figured out what needed done. Hopefully they didn't screw it up....$140 and a few days later, I don't see any drippage on my garage floor. Fortunately, my neighbor across the street is a MB technician and would bail me out in a pinch! He checked my fluid levels before taking it in, and it was more than a quart low, so he brought it back to full. They must have re-lost that quart during the job, as $28 of the $140 was for a quart of TX fluid! (who knows how much they actually used, however..)
