Classical reverse Lexus RX noises and some tips to preserve your gearbox
Why does the reversing of my Lexus RX make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult task. The sound made by the reversing of your Lexus RX 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 used for the reverse gear.
Tips to limit wear on your clutch and gearbox
- Don’t give a big boost:
Indeed, if you kick the throttle hard when you are in reverse or when you put the vehicle in the revs, you risk to burn your clutch or gnawing at the gearbox pinions. - Never reverse while the vehicle is in motion or vice versa:
Reversing the direction of operation of the gearbox during operation is a very bad practice.

It will therefore be completely usual if you find out a reverse noise on your Lexus RX if you shift gear under these conditions.
