transmission mount

[alex1991]

So I have 18d,XDrive,2011,automatic
and when idle I can feel vibration in steering wheel and in the seats, but as soon the wheels start to spont the vibration is gone (there is noise from engine but that is know issue by X1)
So first what I did where the engine mounts but no luck, then I have put sound isolation on wheel well, doors engine cover ect, and reduced sound for 10dB but the vibration is still there.

So do "we" have transmission mount, there are able to buy but do we have them I am not sure?
Or do you have any ideas what could be a issue.
