When my clutch is released sitting in neutral there is a buzzing noise from the gearbox area, and can be heard within the car. And in first and second gear, the noise is also audible but not as loud.

This includes the various types of rolling bearings used in the gearbox that require stringent noise and vibration testing and measurement of the radial and axial clearances.

Noisy gear trains have been common problem for design engineers for a long time. rowning can reduce vibration and limit noise without increasing costs.

When changing from second to third gear in my 2011 Mitsubishi Triton I hear a grinding noise. But when changing down from fourth to third its fine. The car has done 84,000kms. What is most likely the ...
