因为车辆结构的缘故，很难自己去检查自动变速箱油，一般情况下，出现问题多的就是变速箱的加油口和放油口，在维修保养或更换变速箱油以后，建议各位车主仔细检查。下面来讲讲更换济南变速箱油正确的更换步骤。

Due to the structure of the vehicle, it is difficult to check the automatic transmission oil by yourself. Generally, the oil filler and drain port of the transmission are the main problems. After maintenance or replacement of the transmission oil, it is recommended that you carefully check. Next, we will talk about the correct replacement steps for Jinan transmission oil.

目前市面常见的换油方式主要分成2种：泄放式、与拆油底壳式。由于变速箱内的油道相当复杂，不若引擎般简单，若采省事的自然泄放方式更换，整个换油率大约只到30﹪，有一半以上的自动油都还停留在扭力转换器内，换油率比较低，除非必要否则不会采用此种方法来更换自动油。

At present, the common oil change methods on the market are mainly divided into two types: drain type and oil pan removal type. Since the oil passage in the gearbox is quite complex and not as simple as the engine, if it is replaced by an easy natural discharge method, the overall oil change rate will only be about 30%. More than half of the automatic oil still stays in the torque converter, so the oil change rate is relatively low. Unless necessary, this method will not be used to replace the automatic oil.

至于拆卸油底壳的方式进行换油，虽然多数车的换油率只达40%，但这已足以对应多数车辆的使用环境与需求，只要下次在原厂建议的周期再换油，油质衰退的速度还在可接受范围内，加上对变速箱比较温和、施工难度也不高（有些细节要特别注意），所需时间也相当快速，更重要的是没有拆卸变速箱油底壳的话，无法更换到内部的过滤网（有些车型无法更换），滤网一直没有更换，变速箱内的杂质就无法有效过滤，甚至会影响自动油的流动，严重时会造成明显的换档顿挫情况，也因为这种拆卸油底壳来更换自动油的方式有很多优点，因此成为目前多数车厂采用的主流方式。

As for oil change by disassembling the oil pan, although the oil change rate of most vehicles is only 40%, this is enough to meet the service environment and demand of most vehicles. As long as the oil is changed at the interval recommended by the original manufacturer next time, the speed of oil quality deterioration is still acceptable. In addition, the gearbox is mild, and the construction is not difficult (some details should be paid special attention to). The time required is also quite fast, More importantly, if the transmission oil pan is not removed, the internal filter screen cannot be replaced (some models cannot be replaced). If the filter screen has not been replaced, impurities in the transmission can not be filtered effectively, and even affect the flow of automatic oil. In serious cases, it will cause obvious gear shift jerks, because this method of removing the oil pan to replace automatic oil has many advantages, Therefore, it has become the mainstream mode adopted by most car manufacturers.

自动油的滤网若一直没有更换，会影响自动油的流动，严重时会造成明显的换档顿挫，因此更换自动油时，若有变速箱油底壳的话，建议拆下油底壳来进行换油与换滤芯的动作。

If the filter screen of automatic oil has not been replaced all the time, it will affect the flow of automatic oil, and even cause obvious gear shift jerk. Therefore, when replacing automatic oil, if there is a transmission oil pan, it is recommended to remove the oil pan to change the oil and filter element.

将油底壳锁回去时，由于有些进口车辆的固定螺丝是较软的铝合金，长时间承受自动油的热涨冷缩下，容易出现金属疲劳，因此只要拆下来后需要更换新螺丝，并且使用扭力板手来上锁，以确保螺丝不会锁坏。

When the oil pan is locked back, because the fixing screws of some imported vehicles are made of soft aluminum alloy, which can withstand the thermal expansion and cold contraction of the automatic oil for a long time, and are prone to metal fatigue, it is necessary to replace the screws after removal, and use a torque wrench to lock them to ensure that the screws will not be damaged.

而更换自动油中，需要注意的就是换油时的变速箱温度需降低到常温状态下才能进行（通常是前先进厂静置一晚），至少让自动油温冷却至35度后再能更换新油，原因在于自动箱内泡在油里面的油压阀体，内部为细小油道所组成，且为上下两片合为一体。

In the process of changing the automatic oil, it should be noted that the gearbox temperature should be reduced to normal temperature before changing the oil (usually the day before last, the gearbox should be left in the factory overnight). At least the automatic oil temperature should be cooled to 35 ℃ before changing the new oil. The reason is that the oil pressure valve body inside the automatic oil box, which is soaked in the oil, is composed of small oil passages, and the upper and lower parts are integrated.

若未待油温冷却才更换温度较低的新油，有可能因高低温变化过大，导致整个阀体热涨冷缩不均而变形，使得内部油道产生密封不全漏油，油压无法建立的问题，届时只能更换整个阀体才能解决跳档不顺或顿挫严重的问题。

If the new oil with lower temperature is not replaced until the oil temperature is cooled, it may be deformed due to uneven thermal expansion and contraction of the whole valve body due to excessive changes in high and low temperatures, resulting in incomplete sealing of the internal oil passage and oil leakage, and the oil pressure cannot be established. At that time, only the whole valve body can be replaced to solve the problem of unsmooth gear jump or serious setback.

有些车辆上并没有自动油尺可测试油量，因此泄油时要以量壶来盛装，看泄下的油量为多少后，才知道要补充多少新油进变速箱内，通常依照经验会多倒1升的自动油于填充的容器内，再视情况补进自动变速箱内。

Some vehicles do not have an automatic oil dipstick to test the oil level, so when draining the oil, a measuring pot should be used to fill it. After checking the amount of oil drained, we can know how much new oil to add into the gearbox. Generally, according to experience, we will pour an additional liter of automatic oil into the filled container, and then add it into the automatic gearbox as the case may be.

自动油更换时一定要在冷车状态下进行，这样才不会导致内部阀体变形，且补充新油时不得让自动油温超过45度，超过这个温度会因为自动油的热胀而使油量判断失准，导致油量填充过少，因此需诊断电脑协助才能进行。大家还有补充的欢迎评论留下http://www.jnbsx.com你的经验，或者你遇到的问题。

The automatic oil must be replaced in the cold state, so as not to cause deformation of the internal valve body, and the automatic oil temperature shall not exceed 45 degrees when replenishing new oil. If the temperature exceeds this, the oil volume will be judged inaccurate due to the thermal expansion of the automatic oil, resulting in too little oil filling. Therefore, it can only be carried out with the assistance of the diagnostic computer. You have additional welcome comments left http://www.jnbsx.com Your experience, or your problems.
