Classical reverse Chevrolet Impala noises and some tips to look after your gearbox
Why does the reversing of my Chevrolet Impala make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult action. The sound caused by the reversing of your Chevrolet Impala 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 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:

It will therefore be completely usual if you notice a reverse noise on your Chevrolet Impala if you shift gear under these conditions.
