Classical reverse Ford S-max noises and some tips to look after your gearbox

Why does the reversing of my Ford S-max 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 induced by the reversing of your Ford S-max 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 reduce 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 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 idea. Indeed, the pressure you will exert on the gears will be significant and you will produce 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 typical if you find out a reverse noise on your Ford S-max if you shift gear under these conditions.
