How often should the Aisin 4AT transmission fluid be changed?
2 Answers
Aisin 4AT transmission fluid is generally recommended to be changed every 3 years or 60,000 kilometers. More information about the Aisin 4AT is as follows: 1. As one of the three core components of a vehicle, the transmission plays a role no less important than the engine. Compared to manual transmissions, automatic transmissions are somewhat more delicate, whether they are manual-automatic, dual-clutch, or CVT. Theoretically, the service life of an automatic transmission is not short, at least not less than that of the engine, but in reality, the lifespan of an automatic transmission is the most uncertain, as it is somewhat related to individual driving habits and usage environments. 2. It performs well in mountainous areas, where it can reduce the frequency of gear shifts. Generally, regions with more mountainous terrain still predominantly use 4-speed AT transmissions. Actual fuel consumption needs to be considered comprehensively based on factors such as the engine displacement of the vehicle model, the driver's driving habits, and road conditions.
I've been driving for decades and have used many cars with Aisin 4AT transmissions. Changing the transmission fluid is quite crucial. Generally, it should be changed every 40,000 to 60,000 kilometers or every two years, but don't follow this rigidly—it depends on your driving habits. For example, since I often drive in city traffic with frequent stops and starts, which raises the fluid temperature, I change it earlier, around every 30,000 kilometers. Otherwise, dirty fluid can cause the transmission to become jerky or noisy. When changing the fluid, go to a reputable shop—don't attempt it yourself. They use specialized tools to drain the old fluid and add new fluid, and the cost isn't too high. It's better than spending a fortune on major repairs later. Remember, reddish fluid is good, but if it turns black, it's time for a change.
