    I've had this problem too on my 2002 C240 147K miles, then Replaced the Tranny fluid and can drive for another 300 miles then problem happened again. Already checked for no leaks of fluid.

    Transmission switched to low gear and stayed there - so you can only travel at about 15-20 mph. Mercedes dealership says that the electronics force it into a "safe mode" when this happens so one can not damage the transmission. Despite it being covered fully by warranty, it makes me uneasy in a car with 11k miles!!!
