Gearbox is an important transmission device of automobile. Whether the gearbox can work normally or not, gearbox oil plays a decisive factor. Transmission oil has the function of lubrication and cooling, but it is a consumable. Pay attention to the oil quantity of transmission oil at ordinary times. What happens if the transmission is short of oil?

變速箱缺油什么癥狀

What are the symptoms of transmission oil shortage

1、變速箱缺油，潤滑效果會降低，變速箱容易出現異響，掛檔不順暢，零件磨損加快，易受損；

1. If the gearbox is short of oil, the lubrication effect will be reduced, the gearbox is prone to abnormal noise, the gear shift is not smooth, the wear of parts is accelerated, and it is easy to be damaged;

2、變速箱缺油，冷卻效果會降低，可能會導致變速箱內部溫度升高，嚴重時會燒壞變速箱內部零件，導致變速箱報廢。

2. If the transmission is short of oil, the cooling effect will be reduced, which may lead to the increase of the internal temperature of the transmission. In serious cases, it will burn out the internal parts of the transmission, resulting in the scrapping of the transmission.

3、變速箱缺油，傳動效率會降低，變速器換擋緩慢，導致汽車提速慢，起步無力，油耗增加。

3. The transmission efficiency will be reduced due to the lack of oil in the transmission, and the transmission shifts slowly, resulting in slow acceleration, weak starting and increased fuel consumption.

變速箱油對變速箱的傳動效率有非常大的影響，如果變速箱的傳動效率降低了，會對汽車的油耗產生影響。如果變速箱油油量過低，會導致傳動效率降低，從而增加油耗。油量過高，齒輪旋轉受到的阻力會變大，也會影響變速箱的傳動效率，也會影響油耗。也就是說變速箱油多少都會對油耗造成影響，變速箱油量多少正常呢？該如何查看？

Transmission oil has a great impact on the transmission efficiency of the transmission. If the transmission efficiency of the transmission is reduced, it will affect the fuel consumption of the vehicle. If the transmission oil is too low, it will reduce the transmission efficiency and increase the fuel consumption. If the oil quantity is too high, the resistance to gear rotation will become larger, which will also affect the transmission efficiency of the gearbox and fuel consumption. In other words, the amount of transmission oil will affect the fuel consumption. How much transmission oil is normal? How do I view it?

可以從變速箱油尺中的變速箱油痕跡判斷油量，如果是冷車狀態下的變速箱，油面高度應在油尺刻線的下限附近；如果是熱車狀態下的變速箱，油面高度應在油尺刻線的上限附近。發現變速箱油油量過少，應及時補充。

The oil quantity can be judged from the transmission oil trace in the transmission oil dipstick. If the transmission is in the cold state, the oil level height should be near the lower limit of the marking line of the oil dipstick; If the transmission is in the hot state, the oil level height should be near the upper limit of the marking line of the dipstick. If the transmission oil is found to be too small, it should be replenished in time.
