Classical reverse Toyota C-hr noises and some tips to preserve your gearbox
Why does the reversing of my Toyota C-hr make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The sound caused by the reversing of your Toyota C-hr 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 more quiet 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 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. Indeed, the pressure you will put in on the gears will be significant and you will generate 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 notice a reverse noise on your Toyota C-hr if you shift gear under these conditions.

If you find out a grinding noise when you start in reverse with your Toyota C-hr, it may be the engine mounts that are tired. Certainly, 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 possible that due to their wear the silentblocks no longer absorb the engine vibrations well. In this case, do not hesitate to check out this paper for more details about strut mount noises on Toyota C-hr.
