Heb80.... A friend of mine has a 2003 SLK 320 5 speed and they look identical. They operate exactly the same way and the owner's manuals for both cars have the exact same transmission info. My guess (and it's just a guess) is that it is the exact same. I do know that the engine and electronics are exactly the same as the SLK 320. The Brakes and suspension are all from the SLK too. Just makes sense that the tranny is to.
