Classical reverse Nissan Terrano noises and some tips to maintain your gearbox
Why does the reversing of my Nissan Terrano 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 Nissan Terrano 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 important 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 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. Indeed, the pressure you will apply on the gears will be enormous 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 usual if you find out a reverse noise on your Nissan Terrano if you shift gear under these conditions.

I hear a grinding noise when starting in reverse gear
If you discover a grinding noise when you start in reverse with your Nissan Terrano, 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 possible that due to their wear the silentblocks no longer absorb the engine vibrations well.

If you are subject to a knocking noise when you are in reverse with your Nissan Terrano and this noise tends to amplify as you gain speed. It is possible that you are dealing with a serious issue that needs to be resolved fairly quickly before wrecking your entire gearbox.

I listen to a noise when I go in reverse
Listening a noise when you shift into reverse is normal and linked to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your Nissan Terrano reverse gear makes more noise than before, it is possible that filings have been created and are moving around in it. It is therefore time to empty the box.
