很多車主都知道，如果發動機缺機油，車輛會亮起機油報警燈，以便檢查油尺位置及添加適量機油。而與發動機同樣重要的變速箱是沒有液位報警的，對于任何相對摩擦運動的機械部件油量穩定是非常重要的，那變速箱如果缺油車輛會有哪些表現呢？

　　Many car owners know that if the engine runs low on oil, the vehicle will light up the oil warning light to check the dipstick position and add the appropriate amount of oil. The gearbox, which is equally important as the engine, does not have a fluid level alarm. It is very important for any mechanical components with relative frictional motion to have stable oil levels. So, what will happen to a vehicle if the gearbox runs out of oil?

　　一，給油不走道這是自動變速箱缺油最直觀的表現，這主要是因為變速箱油不足，變速箱內部建立不起來足夠的液壓壓力，離合器片等摩擦部件受到的壓力較小，與鋼片之間打滑、磨損導致的。另外，深踩油門才起步、行駛無力、上坡路困難都是自動變速箱缺油的表現。

　　1、 This is the most obvious manifestation of a lack of oil in an automatic transmission, mainly due to insufficient transmission oil, insufficient hydraulic pressure cannot be established inside the transmission, and friction components such as clutch plates are subjected to less pressure, resulting in slipping and wear between the clutch plates and steel plates. In addition, starting with a deep press on the accelerator, weak driving, and difficulty on uphill roads are all manifestations of automatic transmission fuel shortage.

　　二，變速箱異響手動變速箱缺油異響是最明顯的，當踩下離合器踏板后異響消失，抬起離合器踏板后異響會重新出現。因為手動變速箱的齒輪組基本是硬性咬合，缺油會導致異常磨損，嚴重的甚至齒面燒蝕變藍。手動變速箱經歷缺油故障后，基本上要更換變速箱內部的齒輪與軸承，維修費用還是很高的。

　　2、 The abnormal noise of manual transmission due to lack of oil is the most obvious. The abnormal noise disappears when the clutch pedal is pressed, and reappears when the clutch pedal is lifted. Because the gear set of a manual gearbox is basically rigidly engaged, a lack of oil can cause abnormal wear, and in severe cases, even tooth surface erosion and turning blue. After experiencing a lack of oil in a manual gearbox, it is basically necessary to replace the gears and bearings inside the gearbox, and the maintenance cost is still very high.

　　某第三方檢測機構拆解報告顯示：

　　A dismantling report from a third-party testing agency shows:

　　長期缺油30%的變速箱，行星齒輪磨損量達正常值的8倍。

　　A gearbox with a long-term oil shortage of 30% has planetary gear wear that is 8 times the normal value.

　　CVT鋼帶在油量不足時，使用壽命縮短至原廠的1/5。

　　When the oil level is insufficient, the service life of CVT steel strip is shortened to 1/5 of the original factory.

　　維修費用對比：補充油液僅需200-500元，更換總成達萬元以上。

　　Comparison of repair costs: Adding oil only costs 200-500 yuan, while replacing the assembly costs over 10000 yuan.

　　可以肯定的是，任何變速箱，只要長時間漏油，一定會造成變速箱油不足。但是變速箱的密封性還是很高的，很多車型的變速箱都不會有類似滴油的故障，有也是輕微滲油的現象，滲油要想達到缺變速箱油的程度，需要很長時間的積累。所以為了避免變速箱缺油的故障，定期的檢測就尤為重要了。

　　It can be certain that any gearbox that leaks oil for a long time will inevitably cause insufficient transmission oil. However, the sealing performance of the gearbox is still very high. Many car models' gearboxes do not have similar oil dripping faults, and there is only slight oil leakage. To reach the level of insufficient gearbox oil leakage, it takes a long time to accumulate. So in order to avoid the fault of insufficient oil in the gearbox, regular inspections are particularly important.

　　先說手動，手動變速箱的體上有一個加油口，擰開這個加油口螺絲，只要有油液流出來，或者用手指伸進去，正好能摸到變速箱油液面，就說明變速箱油是足夠的。

　　First, let's talk about manual transmission. There is a fuel port on the body of the manual transmission. By unscrewing the screw of this fuel port, as long as there is oil flowing out or reaching in with your fingers, you can feel the level of the transmission oil, which means that the transmission oil is sufficient.

　　自動變速箱的油量檢測，需要油溫達到正常的工作溫度，對于有油尺的車型，我們直接從油尺上就可以看到變速箱油的液面高度，只要在上下限之間就可以了；如果沒有油尺，我們需要打開加油口螺絲，有少量的油液流出，說明變速箱油量正常，如果沒有油液流出，說明變速箱油不足，需要添加。

　　The oil level detection of automatic transmission requires the oil temperature to reach the normal working temperature. For models with a dipstick, we can directly see the height of the transmission oil level from the dipstick, as long as it is between the upper and lower limits; If there is no dipstick, we need to open the fuel filler screw. If there is a small amount of oil flowing out, it indicates that the transmission oil level is normal. If there is no oil flowing out, it indicates that the transmission oil is insufficient and needs to be refilled.

　　車輛故障提示-雖然變速箱沒有液位報警功能，但是很多車型都會給出變速箱故障或者變速箱油溫高的報警。如果變速箱嚴重缺油，這些警示燈就會亮起。這種情況下檢查一下變速箱有沒有漏油，有問題及時維修。

　　Vehicle malfunction prompt - Although the transmission does not have a fluid level alarm function, many car models will give an alarm for transmission malfunction or high transmission oil temperature. If the gearbox is severely short of oil, these warning lights will light up. In this case, check if there is any oil leakage in the gearbox and repair it promptly if there is a problem.

　　總之，變速箱缺油的表現可能因不同的汽車型號和變速箱類型而有所差異。如果駕駛時體驗到到上述任何一種情況，建議盡早對變速箱進行檢查和維修。

　　In short, the performance of gearbox oil shortage may vary depending on different car models and gearbox types. If you experience any of the above situations while driving, it is recommended to inspect and repair the gearbox as soon as possible.
