What is the approximate lifespan of an AT transmission?
1 Answers
The actual lifespan of an AT transmission is generally over ten years. This is because AT transmissions have a very high torque-bearing capacity, and many off-road vehicles and military vehicles even use this type of transmission. They can handle tough conditions like traversing mountains and being forcefully towed without much issue. Below is more related information: Methods to extend the lifespan of a transmission: 1. Replace the transmission fluid according to the specified time or mileage. Although many manufacturers claim that the transmission is maintenance-free for life, the replacement cycle for transmission fluid is typically between 60,000 to 80,000 kilometers (varies by model). After the first maintenance, it is recommended to replace the fluid every 40,000 to 60,000 kilometers to prevent the fluid from deteriorating. 2. Avoid keeping the gear in D (Drive) for extended periods while driving. Keeping the gear in D means the transmission is continuously working, with internal components rubbing against each other and stirring the fluid, which increases the transmission temperature. Over time, this can cause the transmission fluid to deteriorate prematurely, reducing its lubrication and cooling effectiveness and leading to more severe wear on the transmission. 3. Pay attention to daily driving habits. Ensure the gear matches the speed—avoid driving at low gear with high speed or high gear with low speed. Also, avoid coasting in neutral, as a vehicle without power not only interrupts the oil supply to the transmission but also becomes passive, which is very dangerous. Additionally, do not shift into P (Park) before the vehicle has come to a complete stop, as this can easily damage internal components.
