自动变速箱与发动机、底盘悬挂总称为汽车三大件，其中变速箱结构复杂，因此维修成本很高，一旦变速箱出现故障需要维修，费用可能比修发动机还要贵，因此做好日常的保养尤为重要，而变速箱保养的关键，是变速箱油。而不同的变速箱需要适配专用的变速箱油，下面济南自动变速箱维修人员为您分析：

The automatic transmission, engine and chassis suspension are collectively referred to as the three major parts of automobile. The transmission structure is complex, so the maintenance cost is very high. Once the transmission fails, the maintenance cost may be more expensive than that of the engine. Therefore, it is particularly important to do a good job in daily maintenance. The key to the maintenance of the transmission is the transmission oil. Different gearboxes need to be equipped with special transmission oil. The following is the analysis of Jinan automatic transmission maintenance personnel:

手动变速箱（MT）

Manual transmission (MT)

俗称“手动档”，用手拨动变速杆来改变变速器内的齿轮啮合位置和传动比，从而实现变速，需要配合踩离合器。选用合成型高黏度指数优良基础油和多功能添加剂调配而成。可以在崎岖山路频繁换挡等苛刻工况下正常工作，对机器零部件起到很好的保护作用。

Commonly known as "manual gear", shift the gear lever by hand to change the gear meshing position and transmission ratio in the transmission, so as to achieve speed change. It is necessary to step on the clutch. It is blended with synthetic base oil with high viscosity index and advanced multifunctional additives. It can work normally under harsh conditions such as frequent gear shifting on rugged mountain roads, and play a good role in protecting machine parts.

自动变速箱（AT）

Automatic transmission (AT)

根据油门踏板程度以及车速的变化，同时发动机负荷和汽车的运行工况，自动换入不同挡位工作。自动变速箱油黏度相对较低，好选择抗氧化性和流动性较好的油液，从而提高传动效率。

According to the degree of the accelerator pedal and the change of the vehicle speed, the engine load and the operating conditions of the vehicle will automatically shift into different gears to work. The viscosity of the automatic transmission oil is relatively low, so it is better to select the oil with good oxidation resistance and fluidity to improve the transmission efficiency.

无级变速箱（CVT）

CVT

没有明确挡位之分，省去了复杂的齿轮组合变速传动，只用了两组带轮进行变速传动。因此，为了防止无级变速箱特殊的传动链条打滑，选择的变速箱油需要具有一定的阻尼摩擦力。优异的燃油经济性，有效延长换油周期，降低运行成本；优异的摩擦特性与优异的流变性能，让您拥有很佳的驾乘舒适感。

There is no clear gear division, and the complex gear combination variable transmission is omitted, and only two sets of pulley are used for variable transmission. Therefore, in order to prevent the special transmission chain of the CVT from slipping, the selected transmission oil needs to have certain damping friction. Excellent fuel economy, effectively extending the oil change period and reducing the operating cost; Excellent friction characteristics and excellent rheological properties make you have a good driving comfort.

双离合变速箱（DCT）

Dual clutch transmission (DCT)

顾名思义，有两组离合器。离合器位于发动机与变速器之间，是既能传递动力又能切断动力的传动机构。双离合变速箱结合了手动变速箱和自动变速箱的优点，没有变矩器，而是通过两套离合器的相互交替工作，来实现无间隙换挡。变速箱油，专为湿式双离合变速器开发，使用优良合成型基础油及进口添加剂调和而成，满足双离合变速器的润滑需求，保护爱车。

As the name implies, there are two sets of clutches. The clutch is located between the engine and the transmission. It is a transmission mechanism that can transmit power and cut off power. The dual-clutch transmission combines the advantages of the manual transmission and the automatic transmission. There is no torque converter. Instead, the two sets of clutches work alternately to achieve gearshift without backlash. Transmission oil, specially developed for wet dual-clutch transmission, is blended with excellent synthetic base oil and imported additives to fully meet the lubrication requirements of dual-clutch transmission and fully protect your car.

在用车时，要特别注意油液高度，既不能过多，也不能过少。油面过低，容易导致自动变速箱烧毁，而油面过高，则可能导致自动变速箱内部温度过高，出现异响等故障。更多相关内容就来我们网站http://www.jnbsx.com咨询了解吧！

When using the vehicle, pay special attention to the oil level, neither too much nor too little. If the oil level is too low, it is easy to cause the automatic transmission to burn out, while if the oil level is too high, it may cause the internal temperature of the automatic transmission to be too high, abnormal noise and other faults.
