noise when accelerating ( clunk someting )

anybody got this to? or now what it is?
to me its sounds something in the transmission? no rattling but maybe someting moving more then it supose to.?

 

clunk is just my discription do you know what clunk needs to sound like?
anyway at the beginning i have gained the audoi 2 times where this " clunk" is .

after that i did not do this because i hoped it was clear
also i cut the parts inbetween zo you dont have to lisen to a long drive and taken out the "clunk" moments

its only when i stop and drive off again and something when i brake also.

to me it sounds like its from the transmission

if i would have warning messages then i would have know there is really something wrong
i personally thing there is a littlebit more movement in the transmission then is normal.

i also put a link uit to lucsious garage... hope that they responde . with al they know they maybe have some info about it.
