Classical reverse Renault Laguna noises and some tips to preserve your gearbox
Why does the reversing of my Renault Laguna 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 generated by the reversing of your Renault Laguna 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 used for the reverse gear.
Tips to reduce wear on your clutch and gearbox
- Don’t give a big boost:
In fact, 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 apply on the gears will be monumental 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 typical if you find out a reverse noise on your Renault Laguna if you shift gear under these conditions.

I listen to a grinding noise when starting in reverse gear
If you experience a grinding noise when you start in reverse with your Renault Laguna, it may be the engine mounts that are tired.
