汽车自动变速箱内部有润滑油的，时间久了会变脏变质需要更换。一般是六万公里建议更换，长时间不换油会导致换挡冲击，偶尔不走车，长时间高速以后锁挡等等问题。济南自动变速箱维修人员提醒您，换油很重要，不过换油的方式更重要，一般常采用的是重力换油和循环换油两种。

There is lubricating oil in the automatic transmission, which will become dirty and deteriorated after a long time and needs to be replaced. It is generally recommended to replace it after 60000 km. If you do not change the oil for a long time, it will cause gear shifting impact. Sometimes you do not drive the car. After a long time of high speed, you can lock the gear. Jinan automatic transmission maintenance personnel remind you that oil change is very important, but the way of oil change is more important. Generally, gravity oil change and circulating oil change are used.

动换油是拆掉底壳螺栓，让它自己流干净然后加注新油，这种方式简单，不过换油的量很少，也就是说重力放油大概也就是能放出三分之一的油，其他的油你是放不出来的。加上新油以后只是会有点改善并不能换干净。大家是不是想知道那三分之二的油在哪里?

To change the oil, remove the bolts on the bottom casing, let it drain clean and then fill it with new oil. This method is simple, but the amount of oil change is very small. That is to say, gravity drain oil can drain about one-third of the oil, and you can't drain other oil. After adding new oil, it will only improve a little and can't be replaced completely. Do you want to know where the two-thirds of the oil is?

大家都知道的耦合器或者叫做变矩器或者变扭器之类的东西，里面是液力耦合的，里面的油是放不出来的，还有就是阀体内部活塞内部的油是出不来的，因为设计问题是需要保持油道里一直有油的。

As we all know, the coupler or torque converter or torque converter is hydraulic coupling, and the oil in it cannot be drained. In addition, the oil in the piston inside the valve body cannot be drained, because the design problem is to keep the oil in the oil passage all the time.

这个就是变扭器，很多车都有这个，不过有些车没有，比如双离合的，或者部分cv的都没有这个。这个设计原理太复杂我一带而过，这个里面有油通过油来传递动力，进行液力偶合，这个东西里面能存放三汽

This is the torque converter. Many cars have it, but some cars don't have it, such as double clutch or some cv cars don't have it. This design principle is too complicated. I passed it by. There is oil in this one to transmit power through oil and carry out hydraulic coupling. This one can store three steam engines

四升油的样子，有的多有的少，不管有多少你重力换油是放不出来的。换油的时候通过外部变速箱的散热油管进行换油，连接换油机以后启动车辆，波箱内部的油泵运转以后散热油管会有油被泵出通过换油机内部的计量设备计算出流量然后从回油管注入相同量的新油，完成一个循环。就是流出多少旧油泵进去多少新油。

The appearance of four liters of oil, some more, some less, no matter how much you change the gravity oil is not released. When changing the oil, the oil shall be changed through the radiator oil pipe of the external gearbox. After connecting the oil changer, the vehicle shall be started. After the oil pump inside the wave box runs, the oil in the radiator oil pipe will be pumped out. The flow will be calculated through the metering equipment inside the oil changer, and then the same amount of new oil will be injected from the oil return pipe to complete a cycle. It's just how much old oil goes out and how much new oil goes in.

换油的时候可以从可视窗口看到新旧油，一般来说这种换油方式 ，不过用的油量也比较大，一般来说都在十几升左右的样子。因为内部在工作会把内部所有的油都泵出来，包括阀体活塞里面的油都会泵出来，更换值得推荐。更多相关信息的了解就来我们网站http://www.jnbsx.com进行咨询了解吧！

When changing the oil, you can see the old and new oil from the visual window. Generally speaking, this method of oil change uses a large amount of oil, which is generally about ten liters. Because the internal operation will pump out all the internal oil, including the oil in the valve body piston, replacement is recommended.
