What are the causes and solutions for abnormal noise in the transmission?

Reasons and solutions for abnormal noise in the transmission: 1. Incomplete clutch disengagement. Prolonged operation in this manner not only causes abnormal noise but also shortens the lifespan of the transmission and clutch over time. The solution is to standardize gear-shifting operations. 2. Damaged gears or broken connecting bolts. The solution is to have a professional inspect and identify the specific issue, then analyze and address it accordingly. 3. Worn-out transmission mount. This not only causes abnormal noise but also severe shaking and resonance with the vehicle body, increasing interior vibrations. If completely broken, it can affect gear shifting, causing the transmission to shake with each shift, and the impact can be felt inside the vehicle. The solution is to replace the transmission mount.
I hear a ticking or humming noise from the transmission while driving, which is quite unnerving. Common causes include aged or insufficient lubricant, or increased friction due to wear on internal components like bearings and gears. To address it, I first check the color and level of the transmission fluid—if it's dark or too low, I replace it with fresh fluid. If the noise persists, I take it to a repair shop for inspection, as worn parts may need replacement. To prevent such noises, avoid using cheap, low-quality oil and stick to maintenance every 5,000 kilometers or six months. Last time, I ignored it for a month and ended up spending over a thousand on major repairs—big regret. Driving habits also matter; avoiding sudden braking and hard acceleration helps extend the transmission's lifespan.
When there is abnormal noise in the transmission, I can hear sounds similar to metal grinding or squeaking. It's usually caused by component issues, such as rusted bearings, worn gears, or deteriorated oil leading to insufficient protection. The solution is quite straightforward: simple maintenance will do, like topping up with high-quality transmission fluid yourself; if the noise persists, have a professional mechanic disassemble and inspect it—they can identify and replace the damaged parts. My experience tells me not to ignore these signals, or the transmission might completely fail. Additionally, excessive vehicle load or frequent uphill driving can accelerate wear, so it's best to reduce such aggressive operations. Regular oil changes and careful driving naturally reduce abnormal noises significantly.
