Classical reverse Volkswagen Passat 8 noises and some tips to preserve your gearbox
Why does the reversing of my Volkswagen Passat 8 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult task. The noise caused by the reversing of your Volkswagen Passat 8 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 more quiet than with spur gears implemented for the reverse gear.
Tips to reduce wear on your clutch and gearbox
- Don’t give a big boost:
Indeed, if you kick the throttle hard when you are in reverse or when you put the vehicle in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the vehicle is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad choice. Indeed, the pressure you will put in on the gears will be significant and you will make a premature wear and tear of the gears. You can even destroy the gears of your gearbox at speed by doing so. It will therefore be completely usual if you perceive a reverse noise on your Volkswagen Passat 8 if you shift gear under these conditions.
