What are the causes of transmission failure?

Reasons for transmission failure: There may be a fault in the power electronic control system, possibly due to a faulty connection line of a certain sensor in the transmission; lack of automatic transmission fluid; the automatic transmission overheating or failure to increase speed due to a slipping one-way clutch, etc. Functions of the transmission: 1. Change the transmission ratio: To meet the traction needs under different driving conditions, allowing the engine to operate as much as possible under favorable working conditions and meet possible speed requirements. 2. Enable reverse driving: To meet the need for the vehicle to move backward. The engine crankshaft generally only rotates in one direction, but the vehicle sometimes needs to move backward, hence the reverse gear in the transmission is often used to achieve this. 3. Interrupt power transmission: To interrupt power transmission to the drive wheels when the engine is started, idling, the vehicle is shifting gears, or when it is necessary to stop for power output. 4. Enable neutral gear: When the clutch is engaged, the transmission can output no power. For example, it ensures that the driver can release the clutch pedal and leave the driver's seat without the engine stalling.
I've been driving for over a decade, and when it comes to transmission failures, the most common issues are mechanical ones, like gear wear or aging clutch plates, usually caused by prolonged use or frequent sudden acceleration and deceleration. Insufficient or deteriorated fluid is also a big deal—if transmission fluid leaks or hasn't been changed for too long, poor lubrication can cause parts to seize or overheat, eventually leading to failure. Minor problems might also occur with the driveshaft or bearings, which can get damaged from driving too much on bumpy roads. Prevention is simple: check the fluid regularly, avoid harsh shifting, and if you hear unusual noises or experience jerky gear changes, visit a mechanic right away to avoid bigger problems. Every driver knows the transmission is the heart of a car—maintaining it well can extend your vehicle's lifespan. In short, these tips have saved me a lot of trouble on the road.
