Classical reverse Alfa Romeo 147 noises and some tips to maintain your gearbox
Why does the reversing of my Alfa Romeo 147 make a different noise from my other speeds?
De facto, adding all gears, bearings and pinions into a gearbox is a difficult process. The sound created by the reversing of your Alfa Romeo 147 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 much less important than with spur gears used for the reverse gear.
Tips to limit wear on your clutch and gearbox

You can even destroy the gears of your gearbox at speed by doing so. It will therefore be completely common if you notice a reverse noise on your Alfa Romeo 147 if you shift gear under these conditions.
