Is the acceleration of the new Elysee buzzing?

One of the main reasons for the buzzing may be the friction generated by the gearbox, which may be caused by the wear of gearbox bearings and the reduction of lubricating fluid. Gearbox is a more precise and complicated part in automobile parts. There is abnormal noise when driving, and the abnormal noise disappears when stepping on the clutch pedal, so it is likely that there is something wrong with the parts of the gearbox. Gears in the gearbox are generally sleeved on the shaft, which is equipped with needle bearings. If the rolling bearing in a certain gear is broken, it will affect the meshing, and there will be noise without radial positioning.
