What is the lifespan of the Aisin 8AT transmission?
2 Answers
It can last for 10 years or 150,000 kilometers. Below is some relevant information about AT transmissions: 1. Introduction: The AT transmission, commonly known as the mechanical transmission, uses planetary gears and a torque converter to perform gear shifting operations, replacing the clutch in manual transmissions and freeing the driver's left foot. Due to its compact size and durability, it is widely favored by Japanese brands. The development of AT transmissions dates back to the 1970s and 1980s, and after decades of advancement, the technology has become very mature. 2. Disadvantages: The drawbacks of AT transmissions are also quite evident, including a complex structure, high manufacturing difficulty, which leads to a higher failure rate. Additionally, AT transmissions can produce noticeable jerks during gear shifts.
The lifespan of the Aisin 8AT transmission is generally quite long. Based on my years of driving experience, with proper maintenance, it can easily last over 200,000 kilometers. The key lies in upkeep: I make it a habit to change the transmission fluid every 60,000 kilometers and avoid overheating, such as by refraining from frequent sudden acceleration in congested areas. The internal components of this transmission are robust, but if the fluid isn’t changed, accumulated contaminants can wear down the gears, leading to rough shifting or even failure. Additionally, driving style plays a big role—I mostly drive on highways, so wear is minimal; frequent starts and stops in city driving accelerate wear. Overall, Aisin is a reliable brand, chosen mainly for its durability and peace of mind. With regular check-ups, its lifespan can easily exceed 15 years.
