变速箱、底盘、发动机汽车三大件都知道，但汽修这行里的门道懂的都懂，不懂的外行招招中套路，频繁被坑。今儿咱就说说变速箱，变速箱里可以看成是一堆大小不同的齿轮，通过齿轮不同的配比，来改变汽车行驶的速度。齿轮之间产生摩擦，这时候就需要变速箱油来为之润滑、冷却甚至传动了。

　　I know about the three major components of a car: gearbox, chassis, and engine. However, those who understand the intricacies of auto repair are familiar with them, while those who don't are often tricked by tricks and tricks. Today, let's talk about the gearbox. The gearbox can be seen as a pile of gears of different sizes, which change the speed of the car through different gear ratios. Friction occurs between gears, and transmission oil is needed to lubricate, cool, and even drive them.

　　说到变速箱油，如果变速箱出现换档顿挫，升降档迟缓，甚至行驶时抖动有异响，很可能只是你需要更换变速箱油了。但变速箱油更换这里面就有很多套路，有时其实根本不用换，就比如下面这些套路，看看你中了没？

　　When it comes to gearbox oil, if the gearbox experiences jerking during gear shifts, slow upshifts and downshifts, or even shaking and making abnormal noises while driving, it is likely that you just need to replace the gearbox oil. But there are many tricks involved in changing the transmission oil, and sometimes there is no need to change it at all, just like the following tricks. See if you have fallen for them?

　　套路一：变速箱油要2万公里更换一次

　　Routine 1: The gearbox oil needs to be replaced every 20000 kilometers

　　就比如，有的修理厂为了多收车主钱，经常告诉车主2万公里就要换一次变速箱油，每次更换变速箱油都要浪费800元左右。但事实是，变速箱油换的太勤没有什么用，上次倒进去的油液还没有润滑好就被换出来了，频繁更换变速箱油不但浪费钱还大费周章。那么问题来了，既然不用经常换，那到底多久换一次合适呢？由于机动车变速箱油的更换周期因为车型、设计要求的差别，更换时间没有统一标准，最准确的做法就是看自己汽车的保养手册，如果车辆使用手册中明确给出了更换里程或者使用时间，你就按照标准执行即可。

　　For example, some repair shops often tell car owners that they need to change the transmission oil every 20000 kilometers in order to overcharge them, and each time they change the transmission oil, they waste about 800 yuan. But the fact is, changing the gearbox oil too frequently is useless. The oil poured in last time was replaced before it was properly lubricated. Frequent replacement of gearbox oil not only wastes money but also requires a lot of effort. So the question is, since you don't need to change frequently, how often is it appropriate to change? Due to differences in vehicle models and design requirements, there is no unified standard for the replacement cycle of transmission oil in motor vehicles. The most accurate way is to refer to the maintenance manual of your own car. If the vehicle manual clearly states the replacement mileage or usage time, you can follow the standard.

　　多说一句，如果开车时觉得挂挡生涩，冷启动起步无力，易打滑，即里程没有达到，这时候，你也应该检查下是否需要更换变速箱油。

　　By the way, if you feel that shifting gears feels rough while driving, starting from a cold start feels weak, and you are prone to slipping, that is, if the mileage has not been reached, you should also check if you need to change the transmission oil.

　　套路二：变速箱油以假乱真

　　Routine 2: Using fake gearbox oil to deceive the real

　　变速箱油的价格不便宜，自动挡车型变速箱油的价格在80元左右一升，有人可能会贪便宜，使用价格很低的变速箱油，这类变速箱油可能是假冒伪劣产品，不但起不到散热润滑的作用，还会导致零部件磨损严重。

　　The price of transmission oil is not cheap. The price of transmission oil for automatic transmission models is around 80 yuan per liter. Some people may be tempted by cheap prices and use low-priced transmission oil, which may be counterfeit and inferior products. This type of transmission oil not only fails to provide heat dissipation and lubrication, but also causes serious wear and tear on components.

　　套路三：换变速时，油操作不正确

　　Routine 3: Incorrect oil operation when changing gears

　　很多车友反映，每次去做保养，他们总建议换变速箱油，换一次少则800块，来来回回几次也是大几千了。这个时候，有些门道你要注意了。一般车友更换变速箱油大多数选择在4S店更换，因为4S店会使用原厂变速油箱，当然如果在修理厂更换时，车主需要注意到变速箱油标号的问题。除此之外，更换变速箱的方法也非常关键，很多时候变速箱油放不干净，对于以后的使用还是有很大影响的。

　　Many car enthusiasts have reported that every time they go for maintenance, they always recommend changing the transmission oil, which can cost as little as 800 yuan per change and several thousand yuan per round trip. At this point, there are some tricks you need to pay attention to. Most car owners choose to replace their gearbox oil at a 4S dealership because they use the original gearbox oil tank. Of course, if replacing it at a repair shop, the owner needs to pay attention to the issue of the gearbox oil grade. In addition, the method of replacing the gearbox is also crucial. Often, the gearbox oil cannot be completely drained, which can have a significant impact on future use.

　　目前大部分的维修店还是采用传统的手法换油，这种方法的优点是操作方便，耗时短，但缺点是换油不彻底，放出的油液只占原来的15%-30%，而大部分的酒油液依然存在，采用这种方法换油后，新旧油液混合，变速箱里的杂质仍然比较多，这样之后靠缩短换油周期来进行弥补，所以你不掏钱谁掏钱呢？

　　At present, most repair shops still use traditional methods to change oil. The advantage of this method is that it is easy to operate and time-consuming, but the disadvantage is that the oil change is not thorough, and the released oil only accounts for 15% -30% of the original, while most of the wine oil still exists. After using this method to change oil, the new and old oil mix, and there are still many impurities in the gearbox. In this way, the oil change cycle can be shortened to make up for it. So who will pay if you don't pay?
