變速箱油是保證變速箱系統清潔的油類用品，能保證變速箱正常工作并起有潤滑、散熱、清洗、密封和傳導動力的作用。那為什么換完變速箱油反而開車不順暢？濟南變速箱油廠家認為多半是以下三個原因。

Transmission oil is an oil product that ensures the cleanliness of the transmission system. It can ensure the normal operation of the transmission and plays a role in lubrication, heat dissipation, cleaning, sealing, and power transmission. Why is it that after changing the transmission oil, the driving is not smooth? Jinan transmission oil manufacturers believe that there are mostly three reasons.

油品

Oils 

由于各種變速箱里的元件各不相同，其所需的油液流動速率、密度、摩擦性和膨脹系數都有所不同。所以更換變速箱油時，必須嚴格按照說明書上所說的品種和標號去換，如果加錯變速箱油，不但會對變速箱內的電子元件和金屬部件造成磨損，還會對變速箱的密封造成損壞，導致汽車行駛時出現各種不順暢的感覺。

Due to the different components in various transmissions, the required oil flow rate, density, friction, and expansion coefficient vary. So when replacing the gearbox oil, it is necessary to strictly follow the variety and label stated in the manual. If the gearbox oil is added incorrectly, it will not only cause wear and tear to the electronic and metal components inside the gearbox, but also damage the sealing of the gearbox, causing various unpleasant feelings when the car is driving.

換油方式

Oil change method

我們常見更換變速箱油的方法有重力換油法和循環換油法。循環機換油法的費用較高，但是換油徹底，更換率高達95%以上，避免新舊油混合在一起造成傳動下降。

Our common methods for changing transmission oil include gravity oil change and cyclic oil change. The cost of the oil change method for the circulating machine is relatively high, but the oil change is thorough, with a replacement rate of over 95%, to avoid the mixing of new and old oil causing transmission decline.

重力換油經濟實惠而且操作簡單，一般車輛需要4~5升變速箱油即可。但是變速箱結構復雜，常壓下靜態換油的方法仍有的變速箱油不能排出變速箱，換油不徹底。

Gravity oil change is economical and easy to operate. Generally, vehicles require 4-5 liters of transmission oil. However, the structure of the gearbox is complex, and there are still some methods for static oil change under normal pressure. The gearbox oil cannot be discharged and the oil change is not thorough.

新舊油混合在一起也會讓油和變速箱不能好好磨合，在換擋時也會出現比較明顯的頓挫感。 所以如果想把變速箱內的舊油排干凈，建議使用循環機換油。

Mixing new and old oil can also make it difficult for the oil and gearbox to blend in well, and there may be a noticeable jerky sensation when shifting gears. So if you want to drain the old oil in the gearbox thoroughly, it is recommended to use a circulation machine to change the oil.

磨合期

Break-in period

因為舊的變速箱油使用時間過久后會慢慢變得粘稠，出現雜質和沉淀物，而汽車也在不知不覺中習慣變速箱油的改變。

Because old transmission oil will gradually become viscous after prolonged use, resulting in impurities and sediment, and cars are also unconsciously accustomed to changes in transmission oil.

突然換成了又清又稀的新變速箱油，汽車也需要一個緩沖的時間，齒輪之間需要重新適應磨合，所以在剛換完變速箱油后也會出現頓挫的情況，汽車多多行駛，這個情況就會慢慢消失。

Suddenly replaced with a clean and thin new transmission oil, the car also needs a buffering time, and the gears need to adapt to running in again. Therefore, after just changing the transmission oil, there will also be a jerky situation. If the car drives more, this situation will gradually disappear.

如果替換的變速箱油符合更換需求，變速箱內也未曾留下舊油，在經過長時間的行駛下汽車依舊有明顯的頓挫感，那就要考慮汽車的變速箱是不是損壞了，這時候好去線下維修門店檢查變速箱的情況，以免變速箱出現更大的問題。更多相關內容就來我們網站http://www.ihudie.cn咨詢！

If the replacement gearbox oil meets the replacement requirements and there is no old oil left in the gearbox, and the car still has a noticeable jerk after a long time of driving, then it is necessary to consider whether the gearbox is damaged. At this time, it is good to go to an offline repair shop to check the condition of the gearbox to avoid further problems with the gearbox.
