Classical reverse Renault Koleos noises and some tips to look after your gearbox
Why does the reversing of my Renault Koleos make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult task. The sound caused by the reversing of your Renault Koleos is logical. It can be explained in a fairly simple way. Indeed, 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 much less important than with spur gears used for the reverse gear.
