Dual-clutch transmissions are not called automatics, and there is no
fluid coupling. Take a look here, pull up the video under "Take a look
at M double clutch transmission in action" After a few minutes there is
an exploded view and you can see the flywheel and two clutches. No fluid
coupling at all:

When you are sitting at idle there is no engagement whatsoever until you
give it a little throttle. If you tap the accellerator a little it will
start engaging. This is what I felt in a 2008 M3. Depending on how I set
the transmission "dynamic" button it varied the way it acted, but it did
not feel "fluid", and the video clearly shows how direct it is.

Best regards,
