I have a B&M shortshift mounted on my T5.
It was mounted before i bought the car..
And it makes a weak sound, and it changes if i press the shifter sideways while driving. Mostly in 2nd and 3rd gear.. I can barely hear the sound in other gears, but its there.

Is it a possibility that it's the shortshift that is mounted wrong or something, and the gearbox is fine?
I have no problems at all with the gearbox, its smooth and free from sounds..
