De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The sound generated by the reversing of your Mercedes Gla is logical. It can be explained in a fairly simple way. In fact, the gears used for conventional speeds (1st to 5th or 6th) are so-called “helical” gears (oblique gears) . The use of such a pinion makes the noise caused by the gears less strong than with spur gears chosen for the reverse gear.
