Classical reverse Lexus IS noises and some tips to maintain your gearbox
Why does the reversing of my Lexus IS 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 made by the reversing of your Lexus IS 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 chosen 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 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 exert 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 common if you experience a reverse noise on your Lexus IS if you shift gear under these conditions.

If you perceive a grinding noise when you start in reverse with your Lexus IS, it may be the engine mounts that are tired.

If you are subject to a knocking noise when you are in reverse with your Lexus IS and this noise tends to amplify as you gain speed. It is possible that you are going through a serious issue that needs to be solved as soon as possible before destroying your entire gearbox.

It is therefore time to empty the box.
