Classical reverse Citroen Grand C4 Picasso noises and some tips to preserve your gearbox
Why does the reversing of my Citroen Grand C4 Picasso make a different noise from my other speeds?
De facto, integrating all gears, bearings and pinions into a gearbox is a difficult exercise. The noise generated by the reversing of your Citroen Grand C4 Picasso 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 implemented for the reverse gear.
Tips to reduce wear on your clutch and gearbox
- Don’t give a big boost:

It will therefore be completely usual if you notice a reverse noise on your Citroen Grand C4 Picasso if you shift gear under these conditions.
