一、如何辨别变速箱油的真伪
1、 How to distinguish the authenticity of transmission oil
1、闻气味，通常好的油都有一股焦糊味。
1. Smell the smell, usually good oil has a burnt smell.
2、看气泡，好的油在摇晃后，很少见气泡。
2. Look at the bubbles. After shaking good oil, it is rare to see bubbles.
3、看流动性，好的油“挂瓶”后，很长时间不净。
3. Judging by its fluidity, good oil can become unclean for a long time after being "bottled".
4、看粘稠度，好的油粘度大，沾手后不容易去掉，且能拉出丝线。
4. Judging by its viscosity, a good oil has a high viscosity and is difficult to remove after being touched, and can also pull out threads.
二、变速箱油变质后对汽车有啥危害
2、 What harm does gearbox oil do to cars after it deteriorates
变速箱油一旦变质将会导致加速无力，油耗增加，异常抖动等情况，严重时甚至堵塞管路导致变速箱过热报废，而且国内鲜有能够大修变速箱的汽修厂，基本上都以更换总成的方式排除故障，非常贵。
Once the gearbox oil deteriorates, it will lead to weak acceleration, increased fuel consumption, abnormal shaking, and in severe cases, even blockage of the pipeline can cause the gearbox to overheat and be scrapped. Moreover, there are few domestic repair garages that can overhaul the gearbox, and most of them eliminate faults by replacing the assembly, which is not very expensive.
三、变速箱油多久换一次
3、 How often do I change the transmission oil
其实期限没有界定，有的人认为变速箱油要定期更换，以2万公里、4万公里、6万公里等为界点，因为4S店、维修师傅都是这么说的，也有的人认为没需要更换，自己开车超过5年，行驶过10多万公里也没出啥毛病，用经验证明经常更换是一种浪费。
In fact, the deadline is not defined. Some people believe that the transmission oil needs to be replaced regularly, with a cutoff point of 20000, 40000, 60000 kilometers, etc. because 4S stores and maintenance technicians all say that, while others believe that it does not need to be replaced. They have driven for more than 5 years and have driven over 100000 kilometers without any problems. Experience has proven that frequent replacement is a waste.
先要明确，换变速箱油也要因车型而定，不同的车型要求不一样，许多汽车的使用说明书上的确写了变速箱油需要按时间进行更换，当然也有的写了免维护，所以要根据实际来判断该不该换。
Firstly, it should be clarified that changing the transmission oil also depends on the vehicle model, and the requirements vary depending on the vehicle model. Many car manuals do state that the transmission oil needs to be changed according to time, and some also state that it is maintenance free. Therefore, it is necessary to judge whether to change it based on actual conditions.
通常，自动变速箱油一般情况下建议每行驶4万多公里更换一次，车主可根据车辆变速器的运行状况来判断是否要换波箱油，如果车辆挂挡顺畅，变速箱噪音变化不大，就可以不换;如果车辆换挡时显得生涩，特别是行驶速度超过100公里后变速箱噪音明显增大，就要考虑是否该更换变速箱油，而手动变速箱油由于其变速器内部结构相对简单，精密度不高，技术也较为成熟，手动变速箱油主要起润滑作用，一般的家用车是3年或者10万公里左右更换一次。
Usually, it is recommended to change the automatic transmission oil every 40000 kilometers. The owner can determine whether to change the transmission oil based on the operating condition of the vehicle's transmission. If the vehicle shifts smoothly and the transmission noise does not change much, it is not necessary to do so; If the vehicle appears jerky when shifting gears, especially when the transmission noise significantly increases after driving speed exceeds 100 kilometers, it is necessary to consider whether to replace the transmission oil. However, manual transmission oil, due to its relatively simple internal structure, low precision, and mature technology, mainly serves as a lubricant. Generally, household cars need to replace it every 3 years or around 100000 kilometers.
四、更换变速箱油需要注意些啥
4、 What should I pay attention to when changing the transmission oil
1、换油可不是仅仅是将放油螺丝打开那么简单，由于变速箱内部比较复杂，这样操作不仅放不干净而且容易将杂质留在内部，好使用循环机进行换油，这样可以将杂质一起处理了。
1. Changing the oil is not just about opening the oil drain screw. Due to the complexity of the gearbox, this operation not only makes it difficult to clean but also easily leaves impurities inside. It is easy to use a circulation machine for oil change, so that impurities can be treated together.
2、选择更换变速箱油时，要严格按照厂家要求进行添加，尽量不要选择非原厂变速箱油，更不能贪图便宜使用假冒伪劣变速箱油。
2. When choosing to replace the transmission oil, it is necessary to strictly follow the manufacturer's requirements for adding, and try not to choose non original transmission oil, let alone seek cheap use of counterfeit and inferior transmission oil.
3、车型不同但是变速箱品牌相同，这个时候还是建议去4S店更换变速箱油，虽然变速箱品牌相同，但是做工、材质和调教也会根据品牌和车型的变化而变化，在这里千万不要贪小失大，要知道虽然变速箱油比较贵，但是维修个变速箱更贵。
3. Although the models are different but the transmission brand is the same, it is still recommended to go to a 4S store to change the transmission oil. Although the transmission brand is the same, the workmanship, materials, and tuning will also change according to the brand and model. Don't be greedy and lose the big here. It should be noted that although the transmission oil is expensive, repairing a gearbox is more expensive.
