变速箱作为第二大汽车核心部件，也是我们的重要保养对象，济南变速箱油在长期工作中会发生变质挥发，加剧变速箱磨损，接下来我们一起来了解变速箱油的基本常识。根据变速箱的种类不同，变速箱油可分为两种，一种是手动变速箱油，一种是自动变速箱油。

As the second largest automobile core component, the gearbox is also our important maintenance object. Jinan gearbox oil will deteriorate and volatilize during long-term work, which will aggravate gearbox wear. Next, let's learn the basic knowledge of gearbox oil. According to different types of transmission, transmission oil can be divided into two types, one is manual transmission oil and the other is automatic transmission oil.

变速箱油一般来讲，变速箱油有三个作用，个作用是散热，齿轮之间的相互摩擦做功，势必会产生大量的热量，这时候需要润滑油进行散热。第二个作用是润滑，减少齿轮间的磨损，使档位结合更加的顺畅。第三个作用就是清洁，保持排挡系统的清洁，延长传动装置的使用寿命。

Generally speaking, the transmission oil has three functions. The first function is to dissipate heat. The mutual friction between gears will certainly generate a large amount of heat. At this time, lubricating oil is required to dissipate heat. The second function is to lubricate, reduce the wear between gears, and make the gear combination more smooth. The third role is to clean, keep the gear system clean and extend the service life of the transmission.

我们何时更换变速箱油要根据车型而定，不同的车型要求不一样。许多车辆的使用说明书上明确标注了变速箱油要经常进行更换，当然有的车型的使用说明书上也写了终身免维护，所以要根据实际情况来判断该不该换。通常情况下，自动变速箱油一般建议4万公里左右更换一次，车主可以根据自己用车的实际情况来判断是否进行更换。

When we change the transmission oil depends on the model. Different models have different requirements. The operating instructions of many vehicles clearly indicate that the transmission oil should be replaced frequently. Of course, the operating instructions of some models also indicate that the maintenance is free for life, so it is necessary to judge whether to replace it according to the actual situation. Generally, it is recommended to replace the automatic transmission oil once every 40000 km. The owner can determine whether to replace it according to the actual situation of his own vehicle.

变速箱油如果车挂挡非常顺畅，变速箱噪音变化也不大，就可以不用更换。如果车辆换挡时，感到有明显的生涩或顿挫感，特别是行驶时速超过一百公里以后，变速箱噪音明显增大，这个时候就要考虑是否更换变速箱油了。

If the transmission oil is very smooth and the noise of the transmission does not change much, it can be replaced. If the vehicle feels obvious astringency or frustration when shifting gears, especially when the speed exceeds 100km / h, the noise of the transmission increases significantly. At this time, it is necessary to consider whether to change the transmission oil.

除此之外，还要经常检查自动变速箱油液位是否正常。而手动变速箱油由于其变速箱内部结构相对来说比较简单，且精密度不高，技术相对比较成熟，故手动变速箱油的更换里程可以适当增加。手动变速箱油主要是起润滑作用，一般的家用车的手动变速箱油是三年或行驶10万公里左右进行更换一次。

In addition, always check whether the oil level of the automatic transmission is normal. Because the internal structure of the manual transmission oil is relatively simple, the precision is not high, and the technology is relatively mature, the replacement mileage of the manual transmission oil can be appropriately increased. The manual transmission oil is mainly used for lubrication. Generally, the manual transmission oil of household vehicles is replaced once every three years or 100000 kilometers.

变速箱油如果长时间不更换变速箱油，变速箱齿轮的磨损必然会快速加剧，严重可造成变速箱提前报废。所以，我们一定要做好及时更换变速箱油的工作。关注我们http://www.jnbsx.com，了解更多内容！

If the transmission oil is not replaced for a long time, the wear of the transmission gear will inevitably increase rapidly, which may cause the transmission to be scrapped in advance. Therefore, we must do a good job in changing the transmission oil in time. Follow us http://www.jnbsx.com Yes, learn more!
