OK, I'm getting old and the memory's failing and I should know this but...
I have just fitted a new (rebuilt) gearbox and all of the clutch paraphernalia. When driving the car I can hear a sound - rather like a straight cut gear noise - when the loud pedal is relaxed. The noise disappears when the clutch pedal is depressed.
Question is, when you depress the clutch pedal is it only the clutch plate that is free of the flywheel or also the first motion shaft?
Or, when the car is moving and in gear and the clutch is depressed, does the gearbox effectively still rotate being driven by the rear wheels?
Is the noise therefore gearbox or clutch?
Cheers, david.
