It is never pleasing to discover a sound on your car that you don’t know where it comes from. You may be wanting to know what to do when you identify a reversing gear noise that continues on your Tesla Model 3? Any gearbox issue can be serious, but before making sure, it is better to do a few checks. Our team has made this content page to help you resolve it. First, we will see what the sources and the different gearbox noises can be on Tesla Model 3, and second, what are the solutions available to you.
Classical reverse Tesla Model 3 noises and some tips to preserve your gearbox
Why does the reversing of my Tesla Model 3 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult task. The sound created by the reversing of your Tesla Model 3 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 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 idea. In fact, the pressure you will exert on the gears will be monumental and you will develop 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 typical if you perceive a reverse noise on your Tesla Model 3 if you shift gear under these conditions.
Different Tesla Model 3 reversing noises and their causes
Finally in this section, we will move on to what you are probably most curious about in this document, to find out about the source of reversing noise on Tesla Model 3. Here are the 3 typical noises you may be victim of.
I find out a grinding noise when starting in reverse gear
If you discover a grinding noise when you start in reverse with your Tesla Model 3, it may be the engine mounts that are tired. Indeed, 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 circumstance, do not hesitate to read this content page for more information about strut mount noises on Tesla Model 3.
An increased reverse knocking noise on Tesla Model 3X
If you are subject to a knocking noise when you are in reverse with your Tesla Model 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 solved very fast before ruining your entire gearbox. In fact, 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 quickly. Take your car to your auto mechanic quickly or browse this content page about gearbox noise on Tesla Model 3 for more information.
I find out a noise when I go in reverse
Finding out 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 Tesla Model 3 reverse gear makes more noise than before, it is plausible that filings have been made and are moving around in it. It is therefore time to empty the box.
