What are the causes of transmission failure?
2 Answers
The causes of transmission failure include: 1. Excessive transmission oil temperature, leading to stubborn dirt and impurities forming blockages, causing solenoid valves to operate poorly and fail to regulate oil pressure; 2. Wear or severe wear of internal transmission components, or damage to gear side surfaces; 3. Hardening and aging of transmission rubber sealing materials, resulting in leaks and reduced hydraulic pressure. The functions of a transmission are: 1. To change the transmission ratio and expand the range of torque and speed variation of the driving wheels; 2. To enable the vehicle to reverse while maintaining the engine's rotation direction; 3. To use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitate gear shifting or power output.
I've been driving for over 20 years and seen plenty of transmission failures. The most common issue is fluid problems—either insufficient oil or degraded fluid from not changing it for too long, which increases gear friction and accelerates wear. Driving habits are also crucial; for instance, sudden acceleration and hard braking put extra strain on the transmission, and overheating can easily damage components. Mechanical wear occurs naturally over time, such as rust or seizing in the shift mechanism, affecting normal operation. External factors like driving through deep water after rain can allow water to seep into the transmission, ruining the oil. I remind my friends to regularly check the fluid condition—if it darkens or develops an odd smell, change it immediately. Drive gently and avoid aggressive maneuvers to save on costly repairs.
