During operation, gearbox malfunctions most often occur due to overloads, rough, forceful gear shifting, problems with transmission fluid, and there are frequent cases of damage to parts after self-repair of the gearbox, when mistakes are made during its assembly and adjustment.
Signs of a malfunction in the gear shift mechanism may include: Incorrect gear engagement.
Noise caused by friction between the clutch and one of the gears when the gearshift lever is in neutral and the engine is running. The noise disappears when the clutch is disengaged or while driving.
When operating a vehicle, the following faults may occur in the gearbox: wear of gears and bearings, breakage of gear teeth (with these faults, noise is heard in the gearbox). Rapid wear of gears can be caused by insufficient oil or no oil at all in the gearbox. Gear breakage is most often caused by careless gear shifting (if, while driving at high speed, you engage first gear and quickly release the clutch pedal).
