Classical reverse Lexus GS noises and some tips to look after your gearbox
Why does the reversing of my Lexus GS 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 created by the reversing of your Lexus GS 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 strong than with spur gears chosen for the reverse gear.
Tips to limit 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 plan. Indeed, the pressure you will put in on the gears will be monumental and you will make 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 common if you perceive a reverse noise on your Lexus GS if you shift gear under these conditions.
