Classical reverse Citroen C3 Aircross noises and some tips to protect your gearbox
Why does the reversing of my Citroen C3 Aircross make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult action. The sound generated by the reversing of your Citroen C3 Aircross 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 more quiet than with spur gears chosen 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 car in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the car is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad idea. In fact, the pressure you will apply 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 normal if you notice a reverse noise on your Citroen C3 Aircross if you shift gear under these conditions.
