She drives fine...just wont shift out of 2nd. I had another MB and experienced 'limp mode'...was horrible. How about the unit in the boot? I pulled it apart and it looked fine...clean as a whistle. I did find a plastic bushing kinda thing down in, Brown, about size of a dime, 1/2" long with collar on one end.
