yes, it does go away whenever the pedal is released regardless of gearbox position. the chattering is a property of the multiple clutches rattling against the "floating" flywheel. on a twin disc you have one floating flywheel. on a triple disc you have 2. when you are in neutral with the pedal released, the clutches are engaged and thus not chattering against the floating flywheel(s). just like why you don't hear the chattering when you're cruising on the road in any gear.
