Any gearbox issue can be severe, but before making sure, it is better to do a few investigations. Our team has created this document to support you fix it.

Classical reverse Nissan Patrol 3 noises and some tips to preserve your gearbox
Why does the reversing of my Nissan Patrol 3 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 induced by the reversing of your Nissan Patrol 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 less strong than with spur gears used for the reverse gear.
Tips to limit 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 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. Indeed, the pressure you will apply on the gears will be monumental and you will develop 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 common if you experience a reverse noise on your Nissan Patrol 3 if you shift gear under these conditions.
Different Nissan Patrol 3 reversing noises and their origins
Finally in this section, we will move on to what you are probably most curious about in this content, to learn about the origin of reversing noise on Nissan Patrol 3. Here are the 3 typical noises you may be victim of.
I listen to a grinding noise when starting in reverse gear
If you listen to a grinding noise when you start in reverse with your Nissan Patrol 3, it may be the engine mounts that are tired. Certainly, when the engine is in reverse gear, due to the pinions we saw above the vibrations generated 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 consult this content for more details about strut mount noises on Nissan Patrol 3.
An increased reverse knocking noise on Nissan Patrol 3X
If you are subject to a knocking noise when you are in reverse with your Nissan Patrol 3 and this noise tends to increase as you gain speed. It is plausible that you are going through a serious issue that needs to be resolved right away before ruining your entire gearbox. Indeed, an intensifying rattling noise means that the gears are damaged. If they are, debris will disperse to the rest of the box and damage other gears before long. Take your vehicle to your auto mechanic quickly or read this content about gearbox noise on Nissan Patrol 3 for more information.
I perceive a noise when I go in reverse
Experiencing a noise when you shift into reverse is normal and related to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Nissan Patrol 3 reverse gear makes more noise than before, it is plausible that filings have been created and are moving around in it. It is therefore time to empty the box.
