Classical reverse Nissan Pathfinder noises and some tips to maintain your gearbox
Why does the reversing of my Nissan Pathfinder 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 created by the reversing of your Nissan Pathfinder 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 limit 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 plan. In fact, the pressure you will exert on the gears will be enormous and you will generate 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 typical if you find out a reverse noise on your Nissan Pathfinder if you shift gear under these conditions.

I listen to a grinding noise when starting in reverse gear
If you find out a grinding noise when you start in reverse with your Nissan Pathfinder, it may be the engine mounts that are tired.
