一、如何辨別變速箱油的真偽
1、 How to distinguish the authenticity of transmission oil
1、聞氣味，通常好的油都有一股焦糊味。
1. Smell the smell, usually good oil has a burnt smell.
2、看氣泡，好的油在搖晃后，很少見氣泡。
2. Look at the bubbles. After shaking good oil, it is rare to see bubbles.
3、看流動性，好的油“掛瓶”后，很長時間不凈。
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，且能拉出絲線。
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、變速箱油變質后對汽車有啥危害
2、 What harm does gearbox oil do to cars after it deteriorates
變速箱油一旦變質將會導致加速無力，油耗增加，異常抖動等情況，嚴重時甚至堵塞管路導致變速箱過熱報廢，而且國內鮮有能夠大修變速箱的汽修廠，基本上都以更換總成的方式排除故障，非常貴。
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、變速箱油多久換一次
3、 How often do I change the transmission oil
其實期限沒有界定，有的人認為變速箱油要定期更換，以2萬公里、4萬公里、6萬公里等為界點，因為4S店、維修師傅都是這么說的，也有的人認為沒需要更換，自己開車超過5年，行駛過10多萬公里也沒出啥毛病，用經驗證明經常更換是一種浪費。
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.
先要明確，換變速箱油也要因車型而定，不同的車型要求不一樣，許多汽車的使用說明書上的確寫了變速箱油需要按時間進行更換，當然也有的寫了免維護，所以要根據實際來判斷該不該換。
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，自動變速箱油一般情況下建議每行駛4萬多公里更換一次，車主可根據車輛變速器的運行狀況來判斷是否要換波箱油，如果車輛掛擋順暢，變速箱噪音變化不大，就可以不換;如果車輛換擋時顯得生澀，特別是行駛速度超過100公里后變速箱噪音明顯增大，就要考慮是否該更換變速箱油，而手動變速箱油由于其變速器內部結構相對簡單，精密度不高，技術也較為成熟，手動變速箱油主要起潤滑作用，一般的家用車是3年或者10萬公里左右更換一次。
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、更換變速箱油需要注意些啥
4、 What should I pay attention to when changing the transmission oil
1、換油可不是僅僅是將放油螺絲打開那么簡單，由于變速箱內部比較復雜，這樣操作不僅放不干凈而且容易將雜質留在內部，好使用循環機進行換油，這樣可以將雜質一起處理了。
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、選擇更換變速箱油時，要嚴格按照廠家要求進行添加，盡量不要選擇非原廠變速箱油，更不能貪圖便宜使用假冒偽劣變速箱油。
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、車型不同但是變速箱品牌相同，這個時候還是建議去4S店更換變速箱油，雖然變速箱品牌相同，但是做工、材質和調教也會根據品牌和車型的變化而變化，在這里千萬不要貪小失大，要知道雖然變速箱油比較貴，但是維修個變速箱更貴。
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.
