1.6 cr tdi gearbox noise

[CamJeremiah]

Hi, just wondering if anybody could offer me some advice. My cars recently started making a rattling noise that’s coming from the gearbox. Happens more so when under load but does do it without any stress on the gearbox itself. Doesn’t go away by changing gear/depressing the clutch but seems to lessen at 60/70 mph. Cars on 67k.

Any help would be greatly appreciated, thanks in advance.

Cam.
