不同車型，不同型號的變速箱油，它的更換週期是存在區別的。大部分車型都是6到8萬公里左右的樣子進行更換。具體的更換週期你可以依據保養手冊上的來看
至於如何判斷變速箱中的油是否需要更換?
可以與你平時開車時的感覺做對比，如果某天汽車在行駛過程出現闖動的現象，或冷車時變速箱發出異響，又或者換擋時頓挫感加劇那就得考慮是要更換變速箱油了.
其次也可以去觀察變速油的液體顏色來判斷，如果發現液體為深棕色或黑色，那就是需要更換變速箱油了。
變速箱油判斷是否該更換方法
判斷變速箱油是否需要更換，應該從以下幾方面綜合判斷:判斷以前應該使發動機處於工作溫度以後等溫度降低到50°C以下時進行，不同的車型要求不一樣。
1、外觀和氣味: 正常的ATF變速箱油的油質應該清澈純淨，如果變速箱油顏色變黑，有明顯的焦糊味道，用手撚一撚感覺有明顯雜質，需要更換。需要特別說明的是由於變速箱油濾芯的存在，大的顆粒狀雜質都被過濾吸附到變速箱油底殼內，一般是撚不出來明顯的金屬屑或雜質，但可以看到裡面會有一些絮狀物。
2、變速箱溫度:在同樣駕駛環境時，變速箱油溫經常報警、顯示油溫過高，這有可能是變速箱油長時間使用導致雜質過多，熱傳遞性能差導致，綜合判斷如果發動機水溫正常，就應該考慮是變速箱油的抗泡沫性能變差導致，此時就需要考慮是否變速箱油需要更換
3、變速箱駕駛表現: 變速箱油雜質過多時，會影響閥體的關閉和打開動作，造成延遲或閉合不嚴，影響管路的油壓，此時就有可能導致行駛時頓挫、闖動、異響、噪音增大等現象。上述的幾個情況要結合變汽車行駛里程綜合判斷，才能辨別變速箱油是否需要更換.

There are differences in the replacement intervals for different models and transmission fluids. Most models are changed at around 60,000 to 80,000 km. The exact replacement intervals can be found in the maintenance manual.
How can I tell if the oil in my gearbox needs to be changed?
You can compare it to the way you feel when you drive. If the car is gurgling one day, or if the gearbox rattles when cold, or if there is an increase in frustration when shifting gears, then you should consider changing the gearbox oil.
If the fluid is found to be dark brown or black, then it is time to replace the transmission fluid.
How to determine if the transmission fluid should be replaced
To determine whether the transmission fluid needs to be replaced, the following aspects should be taken into account: the engine should be kept at operating temperature and the temperature should be reduced to below 50°C. Different models have different requirements.
1. Appearance and smell: Normal ATF gearbox oil should be clear and pure, if the gearbox oil becomes black in colour, has an obvious burnt smell, and feels obviously impurities when twisted by hand, it needs to be replaced. It should be noted that due to the presence of the transmission oil filter, large particles of impurities are filtered and adsorbed into the transmission oil sump, so generally speaking, no metal shavings or impurities can be twisted, but some flocculent material can be seen inside.
2、Transfer case temperature: In the same driving environment, the transmission oil temperature is often alarmed, showing that the oil temperature is too high, which may be caused by the long time use of transmission oil, resulting in too much impurities and poor heat transfer performance.
3, transmission driving performance: transmission oil impurities too much, will affect the closing and opening action of the valve body, resulting in delay or closure is not strict, affecting the oil pressure of the pipeline, then it may lead to driving stutter, gushing, noise, etc. phenomenon. The above-mentioned situations should be combined with the mileage of the vehicle to determine whether the transmission fluid needs to be replaced.
