变速箱作为汽车三大件（发动机、变速箱和底盘）之一，是汽车传动系统的核心部件。变速箱的作用是改变传动比，扩大驱动轮的扭矩和转速。根据工作原理，变速箱分为手动和自动两种，这就是我们常说的手动变速器和自动变速器。变速箱保养主要是定期更换变速器油，与发动机保养换油相同，但变速器换油周期较长。
As one of the three major components of a car (engine, gearbox, and chassis), the gearbox is the core component of the car's transmission system. The function of a gearbox is to change the transmission ratio and expand the torque and speed of the drive wheels. According to the working principle, the transmission is divided into manual transmission and automatic transmission, which are often referred to as Manual transmission and automatic transmission. Transmission maintenance mainly involves regularly changing the transmission oil, which is the same as engine maintenance, but the transmission oil change interval is longer.
Below, Shandong gearbox maintenance manufacturers will discuss the precautions for automobile gearbox maintenance:
变速箱机油的更换周期因变速箱类型而异。手动变速器油，俗称齿轮油，一般更换周期建议在6-8万左右。自动变速器进一步细分为AT（液压自动变速器）、CVT（连续可变自动变速器）、DCT或DSG（双离合）和AMT（电子机械自动变速器）。
The change interval for transmission oil varies depending on the type of transmission. The Manual transmission oil, commonly known as Gear oil, is generally recommended to be replaced at a interval of about 60000 km to 80000 km. Automatic transmissions are further subdivided into AT (hydraulic automatic transmission), CVT (continuously variable automatic transmission), DCT or DSG (dual clutch), and AMT (electronic mechanical automatic transmission).
一般建议更换AT变速器油，更换间隔为60000左右，CVT变速箱油更换间隔为80000左右。双离合自动变速器分为干式和湿式，干式润滑油有两种，即齿轮油和阀体油，建议更换周期为40000左右。湿双离合变速器油建议每60000更换一次左右。
It is generally recommended to replace the AT transmission oil at an interval of approximately 60000 kilometers, and the CVT transmission oil at an interval of approximately 80000 kilometers. Dual clutch automatic transmission is divided into dry type and wet type. There are two types of dry lubricating oil, namely Gear oil and valve body oil. It is recommended that the replacement cycle be about 40000 km. It is recommended to replace the wet dual clutch transmission oil approximately every 60000 kilometers.
AMT变速箱实际上是带有一套电子控制装置的手动变速器，本质上还是手动变速器，根据手动变速器的换油周期，可以做到。如果汽车经常剧烈行驶或超载，可适当缩短更换周期。以上齿轮箱换油周期为值，请参考汽车手册或向制造商咨询具体数值。
AMT transmission is actually a Manual transmission with a set of electronic control devices. It is essentially a Manual transmission, which can be achieved according to the oil change cycle of Manual transmission. If the car is frequently driven violently or overloaded, the replacement cycle can be appropriately shortened. The above gearbox oil change intervals are recommended values. Please refer to the car manual or consult the manufacturer for specific values.
更换变速器油有两种方式，手动换油和自动换油。手动换油是传统的重力换油，与换油相同。自动换油是用特殊的变速器换油机器来循环换油，这样既干净又彻底，但用油量大，昂贵。
There are two ways to change the transmission oil, manual oil change and automatic oil change. Manual oil change is a traditional gravity oil change, which is the same as oil change. Automatic oil change is the use of a special transmission oil change machine to cycle the oil change, which is clean and thorough, but requires a large amount of oil and is expensive.
Each car mainly pays attention to the maintenance of the gearbox, without waiting for problems to be fixed. This is an era of repair rather than repair. Don't think about 'running horses and not eating grass'. For more related matters, come to our website http://www.jnbsx.com consulting service
