Is it necessary to repair transmission noise?

[LeHaley]

Transmission noise should be repaired. The causes of transmission noise failure are as follows: 1. Deformation of the transmission housing; 2. Loose or disassembled bearings; 3. Severe gear wear or broken teeth; 4. Overloading may cause bending of the transmission input or output shaft, or severe wear of the splines on the shaft; 5. Severe wear of the synchronizer. The following are the precursors of transmission failure: 1. Symptoms of transmission slipping. Fault performance: During driving, you can hear the engine idling when accelerating, but the car does not show a significant speed increase and has weak acceleration; another situation is that the car drives normally on flat roads but has weak power when going uphill, and the engine speed is very high. 2. Transmission noise. Fault performance: When the car is idling, driving, or under high-load driving, you hear abnormal noises from the transmission, even loud noises, and there are irregular, dull sounds when shifting gears. 3. Overheating of the transmission. Fault performance: The computer alarm shows that the transmission temperature is too high during driving; or after driving for a while, you feel that the transmission is overheating, even too hot to touch. 4. Symptoms of transmission oil leakage. Fault performance: You can clearly feel that the car is difficult to start, and during driving, although the engine speed increases when stepping on the accelerator, the car does not show obvious signs of acceleration.
