i did it all the time in my last c63. change to m while moving that is. i only put 6000 miles on it but my transmission was very low on fluid at 5500 miles. filling it back up fixed it but im not sure why it was low. i guess it could have been because of switching to m mode while moving?
i wonder if its covered by the warranty?

and why is it harmful to your transmission to change to m mode while moving and its not harmful to the other modes?

How would they know? I didn't know and yes, I have read the manual although obviously not as thoroughly as I thought. That might be recommended, but it aint carved in stone or you wouldnt be able to do it, just like I cant watch a DVD while moving.

Guys... if changing to M mode while moving would damage the transmission, the car would not allow it to happen. It is electronically controlled. Besides, you can manually shift even when in auto mode. If changing the button setting would override a setting mechanically (like a parking brake), then I can see it causing an issue. However, it is electronic and there is zero chance that MB would allow the car to do this if it caused damage.
If the car allows it to occur in motion, then it won't damage the transmission. 90% of owners do not read their manuals carefully enough to pick this up. MB would have a lot of damaged transmissions otherwise. No different than the car won't allow you to downshift and overrev the engine... because it is electronically controlled by the computer. Same thing here.

I, for one, do place the tranmission in park before I switch transmission gears, because it provides for this in the manual. But, I have the older model.
Just curious, have you ever accidentally forgot to shift at redline on this car?

There are numerous things in the manual that are very important for the service and maintenance of the car. Lots of people don't ever read the manual, but that doesn't mean those people are not at risk of damaging there car if they do something that the manual doesn't recommend.

This is the same thing for the transmission. The computer controls what happens. It will not allow a missed shift, it will not allow an overrev, it will not damage the transmission by turning a knob in the car.
No different than the M3. Hit the redline and it bounces off, cutting fuel. Drive on and do it again if you wish. The car will NOT allow you to do real damage.
Same with an untimely downshift. It won't even allow you to do it if it will cause a mechanical over rev of the engine... also known as a money shift for 6MT drivers. It isn't possible in this car unless the computer malfunctioned somehow.
I agree that the manual includes a variety of things important to maintenance and longevity. However, turning a button will NOT cause a catastrophic damage to the transmission... period. If it did, half of the C63s on the road would have been back for transmission work by now because their owners would have tried it without knowing better. MB is not that stupid to allow this to occur.

Doing so would be largely irrelevant. The car cuts fuel when you hit redline thereby not allowing the engine to over rev. You can bounce off the limiter all day. You will just hit the redline, engine cuts fuel, hit the redline, engine cuts fuel, repeat. These cars could rev past redline without real issue as redline is set as a safe place well within tolerances. Sure it would be extra wear and tear keeping RPMs that high but it would do no damage. The car controls this by cutting fuel. On the track, you spend 80% of the time within a couple of thousand RPM of redline and unless careful, will bump against it several times a day. No harm at all.
