CLK gear problems Do you also have such problems with the mechanical 6 gear transmission. It is connected with a lot of effort to insert the 1st gear. I can give a sufferer a few tips. Then I want to clarify that the automatic CLK ́s are by far not as fast as the mechanical ones. I persöhlich had already 260 KM/h on the digital speedometer (of course on straight track). And with the consumption I lie in the city traffic below 8l/100Km.
