Classical reverse GMC Savana noises and some tips to maintain your gearbox
Why does the reversing of my GMC Savana 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 GMC Savana 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 employed for the reverse gear.
