Classical reverse Peugeot 406 noises and some tips to preserve your gearbox

Why does the reversing of my Peugeot 406 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 Peugeot 406 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 less strong than with spur gears implemented for the reverse gear.

Tips to reduce wear on your clutch and gearbox

  • Don’t give a big boost:
    In fact, 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 idea. In fact, the pressure you will exert on the gears will be enormous and you will produce 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 notice a reverse noise on your Peugeot 406 if you shift gear under these conditions.

I acknowledge a grinding noise when starting in reverse gear

If you find out a grinding noise when you start in reverse with your Peugeot 406, 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 made 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 situation, do not hesitate to read this article for more information about strut mount noises on Peugeot 406.

Hearing a noise when you shift into reverse is normal and linked to the gears and sprockets used in the gearbox.

It is therefore time to empty the box.
