AT mission noise

hello everyone.
My 2011Y W204 C63 has a noise coming from the transmission that sounds like a metallic sound.
I'm trying to figure out the cause of this noise, but if anyone knows, please give me some advice.
Kind regards

This is the link address of the video.

I replace the ATF every 60,000km. Both the oil and filter were not in bad condition.

I also changed the differential oil, but nothing changed.
I will try replacing the center bearing.

When driving through tunnels or other places with walls, you can often hear strange noises.

As a symptom, the abnormal noise is not related to engine speed and only occurs when the transmission is rotating.   
It comes out even when you shift to neutral gear while driving.

Try to narrow down if the sound is coming from outside the transmission or inside it.
