Gear Clash When Shifting Gears
Gear Clash When Shifting GearsDiagnostic Aids
Gear clash is a grinding noise, made when shifting gears. You should perform a static shift test and a 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 functioning properly, or the clash does not occur in all gears, inspect for worn or damaged synchronizers, including the sleeves, hubs and the blocking rings. Also inspect for loose mounting bolts or misalignment.
