Classical reverse Mercedes Viano noises and some tips to protect your gearbox
Why does the reversing of my Mercedes Viano make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult process. The noise induced by the reversing of your Mercedes Viano 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 important than with spur gears used for the reverse gear.
Tips to reduce wear on your clutch and gearbox

It will therefore be completely normal if you experience a reverse noise on your Mercedes Viano if you shift gear under these conditions.
