Classical reverse Volvo S90 noises and some tips to protect your gearbox
Why does the reversing of my Volvo S90 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 Volvo S90 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 less important than with spur gears implemented for the reverse gear.
Tips to reduce wear on your clutch and gearbox
