I recently posted a question on this topic and several of you responded that a service pack was released by MB for the 722.6 transmission. I called my dealer and he has no knowledge of any service bulletins. I also called the MBUSA 800 number and they said nothing has been released. Yet more than one person has said they got it. Can you help me by providing specific information so I can help the dealer find it? Is MBUSA not giving me the right info?
