Selector bushings? Not familiar. Sounds pretty simple, but big deal or not? Would selector bushings fail instantaneously as described? I'm trying to gather all the info I can so I can be as knowledgeable as possible when I'm discussing potential issues with a new tech. I've been blessed to have a trusted MB tech/friend since I've owned the car, but he is currently 200 miles away. Thanks for the input. Much appreciated...
