Can an AT Transmission Last 500,000 Kilometers?
1 Answers
AT Transmission Lifespan: AT transmissions have a long service life, offering stable performance and robust durability, essentially matching the lifespan of the vehicle itself, often exceeding ten years. Due to their high torque capacity, many off-road vehicles and military vehicles utilize AT transmissions, capable of enduring tough terrains and heavy towing without issues. However, they are prone to overheating and have relatively poor fuel efficiency. Methods to Extend Transmission Lifespan: 1. Replace transmission fluid according to specified intervals or mileage: While many manufacturers claim their transmissions are maintenance-free for life, the recommended replacement interval for transmission fluid is typically between 60,000 to 80,000 kilometers (varies by model). After the initial service, it is advisable to change the fluid every 40,000 to 60,000 kilometers to prevent degradation. 2. Avoid keeping the transmission in D (Drive) gear when stationary for extended periods: Leaving the transmission in D gear means it remains engaged, causing internal components to continuously rub against each other and agitate the fluid, leading to increased temperatures. Over time, this can prematurely degrade the transmission fluid, reducing its lubrication and cooling effectiveness, thereby accelerating wear on the transmission.
