1. Do automatic transmission fluids require regular replacement?

自动变速箱油如果不及时更换，容易造成变速箱内部油品变质、碎屑增多、磨损加剧，从而产生油路阻塞、起步无力、换挡冲击、传动失效等工作异常。大部分自动变速箱损坏与没有及时更换自动变速箱油有关，做好自动变速箱的保养，才能够增加变速箱的使用寿命，避免高额维修成本！

If the automatic transmission oil is not replaced in a timely manner, it is easy to cause the internal oil of the transmission to deteriorate, increase debris, and intensify wear, resulting in abnormal operation such as blocked oil circuits, weak starting, shifting impact, and transmission failure. Most automatic transmission damage is related to not replacing the automatic transmission oil in a timely manner. Proper maintenance of the automatic transmission can increase the service life of the transmission and avoid high maintenance costs!

2、自动变速箱什么时候换油才算适合？

2. When is an automatic transmission suitable for oil change?

自动变速箱油的更换周期是以行驶公里数或使用时间为准，若在车辆使用手册中同时给出了这两个指标，则哪一项指标先到就先执行。如果车辆使用手册未标明自动变速箱的换油时间，按照汽车维修保养常识和自动变速箱养护规定，正常行驶状态下，建议2年或4~6万公里更换自动变速箱油。

The replacement cycle of automatic transmission oil is based on the mileage or usage time. If both indicators are provided in the vehicle manual, whichever indicator comes first will be executed. If the vehicle manual does not indicate the oil change time for the automatic transmission, it is recommended to replace the automatic transmission oil within 2 years or 40000 to 60000 kilometers under normal driving conditions according to the common knowledge of car maintenance and the maintenance regulations for the automatic transmission.

3、同品牌不同型号的变速箱油能混用吗？

3. Can transmission oils of the same brand and different models be mixed?

汽车变速箱的类型千差万别，变速箱的结构、材质、换挡特性各不相同，需要注意的是摩擦性能、耐热性能、氧化性能、黏度指标等差异很大。同时自动变速箱的工作温度较高、各机件啮合紧密，对于自动变速箱油的质量有较高的要求，所以需要根据不同类型变速箱的润滑传动要求，选择与变速箱品牌和型号匹配的油品。

The types of automotive transmissions vary greatly, with varying structures, materials, and shifting characteristics. It is important to note that there are significant differences in friction, heat resistance, oxidation, and viscosity indicators. At the same time, the working temperature of the automatic transmission is high, and the components are tightly meshed, which has high requirements for the quality of the automatic transmission oil. Therefore, it is necessary to choose the oil that matches the brand and model of the transmission according to the lubrication and transmission requirements of different types of transmissions.

5、机器换油和人工换油有区别吗？

5. Is there a difference between machine oil change and manual oil change?

传统的手动换油法更换自动变速箱油，是打开自动变速箱的放油螺丝，让里面的油液自然排出。虽然操作方便，耗时少，但是只能放掉50%的旧油液，换油效果差，且变速箱内的沉积物并没有得到清理；比较之下，如果使用智能换油机换油，则使用智能换油机产生的压力动态更换变速箱润滑油管和冷却油管中的油。这种方法大约需要1小时。虽然整个过程耗时较长，但其优点是换油比较好，换油率也是比较高，并能清理自动变速器内部的油污和金属碎屑。

The traditional manual oil change method for replacing automatic transmission oil is to open the oil drain screw of the automatic transmission and allow the oil inside to drain naturally. Although it is easy to operate and takes less time, only 50% of the old oil can be drained, resulting in poor oil change effect and the sediment in the gearbox has not been cleaned; By comparison, if an intelligent oil change machine is used for oil change, the pressure generated by the intelligent oil change machine is used to dynamically replace the oil in the lubrication and cooling oil pipes of the transmission. This method takes approximately 1 hour. Although the entire process takes a long time, its advantage is that the oil change is relatively good, the oil change rate is also relatively high, and it can clean the oil stains and metal debris inside the automatic transmission.
