Classical reverse GMC Yukon noises and some tips to maintain your gearbox
Why does the reversing of my GMC Yukon 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 GMC Yukon 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 car in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the car is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad practice. In fact, the pressure you will put in on the gears will be significant 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 normal if you experience a reverse noise on your GMC Yukon if you shift gear under these conditions.

I acknowledge a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your GMC Yukon, 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 conceivable that due to their wear the silentblocks no longer absorb the engine vibrations well. In this case, do not hesitate to check out this document for more information about strut mount noises on GMC Yukon.

If you are subject to a knocking noise when you are in reverse with your GMC Yukon and this noise tends to build up as you gain speed. It is conceivable that you are experiencing a serious trouble that needs to be fixed quickly before destroying your entire gearbox.

I notice a noise when I go in reverse
Hearing a noise when you shift into reverse is normal and connected to the gears and sprockets used in the gearbox. If, on the other hand, you have the feeling that your GMC Yukon reverse gear makes more noise than before, it is conceivable that filings have been produced and are moving around in it. It is therefore time to empty the box.
