Classical reverse Mazda 3 noises and some tips to protect your gearbox
Why does the reversing of my Mazda 3 make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult task. The sound caused by the reversing of your Mazda 3 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:
Certainly, if you kick the throttle hard when you are in reverse or when you put the automobile in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the automobile 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 monumental and you will create a premature wear and tear of the gears. You can even break the gears of your gearbox at speed by doing so. It will therefore be completely common if you hear a reverse noise on your Mazda 3 if you shift gear under these conditions.

I listen to a grinding noise when starting in reverse gear
If you hear a grinding noise when you start in reverse with your Mazda 3, it may be the engine mounts that are tired. In fact, when the engine is in reverse gear, due to the pinions we saw above the vibrations produced by the gearbox are higher and it is therefore plausible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this circumstance, do not hesitate to browse this article for more details about strut mount noises on Mazda 3.
