What is the lifespan of an AT transmission in kilometers?
2 Answers
AT transmissions have a lifespan of 150,000 kilometers. AT transmissions are highly practical, offering stable performance and robust durability. The internal structure of AT transmissions is unique, with an exceptionally high torque capacity, making them commonly used in many off-road vehicles and military vehicles. AT transmissions generally refer to automatic transmissions, which are gear-shifting devices that can automatically shift gears based on vehicle speed and engine RPM, as opposed to manual transmissions. Currently, there are four common types of automatic transmissions in vehicles: hydraulic automatic transmissions, continuously variable transmissions (CVT), electronically controlled mechanical automatic transmissions, and dual-clutch transmissions.
Having driven for nearly 20 years, my experience tells me that the average lifespan of an AT transmission is between 150,000 to 250,000 kilometers, and it really depends on how you use it. With less city traffic and more highway driving, wear and tear are reduced, and the lifespan can extend to 300,000 kilometers without issues. However, if you're stuck in city traffic every day, frequently accelerating and braking hard, the lifespan will be much shorter. The key is to change the transmission fluid regularly—it's recommended to service it every 40,000 to 60,000 kilometers. Clean oil slows down internal component wear and can save you money on major repairs. Also, pay attention to your driving habits—avoid towing heavy loads or climbing steep hills too aggressively to prevent overheating and damage to the transmission. Watch for signs of rough shifting and address them early to prevent small issues from turning into big problems. From a safety perspective, once the transmission exceeds 150,000 kilometers, it's wise to keep a closer eye on it.
