Classical reverse Toyota Yaris noises and some tips to maintain your gearbox
Why does the reversing of my Toyota Yaris 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 made by the reversing of your Toyota Yaris 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 much less important than with spur gears employed for the reverse gear.
Tips to limit 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 choice. Indeed, the pressure you will put in on the gears will be enormous 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 usual if you perceive a reverse noise on your Toyota Yaris if you shift gear under these conditions.
