I do not notice a delay in mine. It may be a half second, but I haven't noticed. I keep my hand off the shifter until I intend to use it as the throw, or movement required to make the shift, is very short and I find myself shifting inadvertently as my body weight shifts in a turn. I did have the transmission flushed at 70,000 mi by a local Mercedes dealership. Mine shifts fast and precisely at the slightest movement of the shifter.
