Gear Clash When Shifting Gears

Gear Clash When Shifting Gears





Diagnostic Aids
Gear clash is a grinding noise that is made when shifting gears. You should also perform a static shift and dynamic shift test. If the transmission develops gear clash, first check the clutch adjustment or faulty clutch condition. A clutch that drags or does not fully engage is the most common cause of gear clash. If the clutch is at fault, the clash should occur in every gear. If the clutch is all right, or the clash does not occur in all gears, check for worn or damaged synchronizers, including the sleeves, hubs and the blocking rings. Also check for loose mounting bolts or misalignment.
