如果自动变速箱长时间不做更换变速箱油等养护项目，变速箱中的杂质会越积越多，后期会影响其性能。下面，我们就来看看自动变速箱的外观检查项目是怎样的吧。

　　If the automatic gearbox does not replace transmission oil and other maintenance items for a long time, the impurities in the gearbox will accumulate more and more, which will affect its performance in the later stage. Next, let's take a look at the appearance inspection items of automatic gearbox.

　　在汽车停车状态下查看自动变速箱壳体外观，是否有漏油的痕迹，变速箱油底壳是否变形。

　　Check the appearance of the automatic transmission shell, whether there are traces of oil leakage, and whether the oil pan of the transmission is deformed when the car is parked.

　　自动变速箱油底壳是车身离地很近的部位之一，如果路面有坑洼或较大的石头，就容易撞击到变速箱油底壳，轻则造成凹陷，重则会破裂漏油。大多数漏油问题，是变速箱的橡胶密封圈长时间承受冷热温度变化，导致密封圈老化变硬失去密封作用。刚开始是渗油，逐渐开始出现滴油现象，时间久了会越来越严重。

　　The oil pan of the automatic transmission is one of the parts of the body close to the ground. If there are potholes or large stones on the road, it is easy to hit the oil pan of the transmission. The light one will cause depression, and the heavy one will break and leak oil. Most of the oil leakage problem is that the rubber sealing ring of the gearbox bears cold and hot temperature changes for a long time, resulting in the aging and hardening of the sealing ring and the loss of sealing effect. It is ooze oil at the beginning, begin to appear drip oil phenomenon gradually, time is long meeting more and more serious.

　　济南自动变速箱维修认为变速箱工作时，其内部温度很高，润滑油产生的蒸气充满变速箱内部，导致箱内压力升高，因此变速箱通常设置有通气孔，以保持内外压力平衡。如果通气孔堵塞，箱内压力升高时就会导致油液从密封圈等处渗出，因此日常养护时应检查变速箱通气孔是否畅通。

　　Ji 'nan automatic transmission maintenance thinks that when the gearbox is working, its internal temperature is very high, and the steam generated by the lubricating oil is full of the inside of the gearbox, leading to the increase of the pressure in the box, so the gearbox is usually provided with a vent, in order to maintain the balance of internal and external pressure. If the vent is blocked, the pressure in the box will lead to oil leaking from the sealing ring and other places, so the daily maintenance should check whether the vent of the gearbox is smooth.

　　有些车辆的变速箱配有油尺，检查油量比较方便，但有些车辆的变速箱油液检查需要通过油底壳上的螺栓进行，因此只能在修理厂进行检查。

　　The gearbox of some vehicles is equipped with a dipstick, which is more convenient to check the oil amount, but the gearbox oil of some vehicles needs to be checked through the bolts on the oil pan, so it can only be checked in the repair shop.

　　自动变速箱一旦出现故障应及时送修，如果仍然继续使用可能会导致变速箱报废等严重后果，切不可大意，以免因小失大。更多内容就来网站www.jnbsx.com咨询吧！

　　Once the automatic gearbox fails, it should be repaired in time. If it continues to be used, it may lead to the scrapping of the gearbox and other serious consequences. It must not be careless so as not to penny wise and pound foolish. More content to the website www.jnbsx.com consultation!
