It is never pleasant to hear a sound on your automobile that you don’t know where it comes from. You may be thinking what to do when you find a reversing gear noise that persists on your Scion tC? Any gearbox issue can be important, but before making sure, it is better to do a few investigations. Our team has made this article to help you solve it. First, we will see what the sources and the different gearbox noises can be on Scion tC, and second, what are the solutions available to you.
Classical reverse Scion tC noises and some tips to look after your gearbox
Why does the reversing of my Scion tC make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult exercise. The noise made by the reversing of your Scion tC 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 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 automobile in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the automobile 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 apply on the gears will be significant 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 normal if you notice a reverse noise on your Scion tC if you shift gear under these conditions.
Several Scion tC reversing noises and their causes
Finally in this section, we will move on to what you are probably most curious about in this article, to learn about the cause of reversing noise on Scion tC. Here are the 3 typical noises you may be victim of.
I listen to a grinding noise when starting in reverse gear
If you hear a grinding noise when you start in reverse with your Scion tC, 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 made 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 paper for more details about strut mount noises on Scion tC.
An increased reverse knocking noise on Scion tCX
If you are subject to a knocking noise when you are in reverse with your Scion tC and this noise tends to increase as you gain speed. It is plausible that you are dealing with a serious issue that needs to be fixed right away before wrecking your entire gearbox. In fact, an intensifying rattling noise means that the gears are damaged. If they are, debris will propagate to the rest of the box and damage other gears quickly. Take your automobile to your auto technician quickly or browse this content page about gearbox noise on Scion tC for more information.
I find out 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 Scion tC reverse gear makes more noise than before, it is plausible that filings have been produced and are moving around in it. It is therefore time to empty the box.
