自动变速器换油注意事项
Automatic transmission oil change precautions
经常检查自动变速器油温，正常情况下，自动变速器油温应在70~80°C之间，也就是说，在正常行驶中途停车休息的时候，用手摸自动变速器外壳，感到有点烫手，但手能在变速器外壳上放不到一秒左右的时间。这样的温度基本就是正常的，这也是参考温度，如果车辆长时间低速行驶，油温会升高。
Check the oil temperature of the automatic transmission frequently. Under normal circumstances, the oil temperature of the automatic transmission should be between 70~80 ° C, that is to say, when stopping and resting during normal driving, touching the automatic transmission housing with your hand feels a little hot, but your hand can not be placed on the transmission housing for about one second. This temperature is basically normal, which is also the reference temperature. If the vehicle runs at low speed for a long time, the oil temperature will rise.
如果油温升高，就要检查自动变速器油液面的高度，往往是液面高度降低后才会导致油温升高。自动变速器油液面高度检查时分为两种情况，一种是冷态检查，就是车辆在停驶状态下，油液的高度应该在油尺的上刻度线位置。另一种是热态检查，就是在车辆行驶后，自动变速器温度达到正常值的时候，抽出油尺，油液高度应在油尺下刻度线。如果太低就要添加。
If the oil temperature rises, it is necessary to check the automatic transmission oil level. Usually, the oil temperature rises only after the level decreases. The automatic transmission oil level is checked in two ways. One is the cold check, which means that the oil level should be at the upper scale of the dipstick when the vehicle is stopped. The other is the hot state inspection, that is, when the automatic transmission temperature reaches the normal value after the vehicle is driven, pull out the dipstick, and the oil level should be at the scale line under the dipstick. Add if it is too low.
济南自动变速箱维修厂家建议大家在检查油液面高度时，同时要观察自动变速器油液的品质，正常的自动变速器油液应该是清澈带红色。如果是深褐色、黑色、或者有焦臭味（滴一滴在手指上用鼻子嗅一下），说明自动变速器曾经过热或长时间没有换油。
Jinan automatic transmission maintenance manufacturer suggests that when checking the oil level, you should also observe the quality of the automatic transmission oil. The normal automatic transmission oil should be clear and red. If it is dark brown, black, or has a burning smell (sniff it with your nose every drop on your finger), it indicates that the automatic transmission has been overheated or has not changed the oil for a long time.
如果其中有黑色颗粒状物质，标明自动变速器内部的离合器片、制动片等烧蚀，应拆开自动变速器进行检查，并彻底清洗其零部件。如果其中有银白色的金属颗粒，或者碎铁屑标明自动变速器内部的阀体、轴承或行星齿轮磨损严重，也必须拆解自动变速器。如果油尺上带有难以擦净的胶状物，说明自动变速器油（ATF）因过热氧化，应更换自动变速器油和清洗滤网。
If there is black granular substance in it, it indicates that the clutch disc, brake disc, etc. inside the automatic transmission are ablated. The automatic transmission shall be disassembled for inspection, and its parts and components shall be thoroughly cleaned. If there are silver white metal particles or scrap iron indicating that the valve body, bearing or planetary gear inside the automatic transmission is seriously worn, the automatic transmission must also be disassembled. If the dipstick has a colloid that is difficult to clean, it indicates that the automatic transmission oil (ATF) is oxidized due to overheating. Replace the ATF and clean the filter screen.
自动变速器换油使用误区
Incorrect use of automatic transmission oil change
误区一：变质才换
Myth 1: change after deterioration
自动变速器油的更换周期是以行驶数或使用时间为准，如果车辆使用手册未标明，则按照6万-8万的里程来更换。
The replacement cycle of automatic transmission oil is based on the mileage or service time. If it is not indicated in the vehicle manual, it shall be replaced according to the mileage of 60000-80000 km.
误区二：两种换油方式
Myth 2: two oil change methods
“手换”操作方便，耗时少，缺点是换油不彻底，只能放掉四分之一三分之一旧油液，大约是4升。“机换”整个过程约需1小时，需油12升左右。这种换油方式的优点是换油比较彻底，能够放掉85%以上的旧油液。
The "manual change" is easy to operate and takes less time. The disadvantage is that the oil change is not complete. Only a quarter to a third of the old oil can be drained, about 4 liters. The whole process of "machine replacement" takes about 1 hour and requires about 12 liters of oil. The advantage of this oil change method is that the oil change is relatively complete, and more than 85% of the old oil can be discharged.
值得注意的是，两种换油方法都要在发动机启动的情况下进行。更换自动变速器油液，在操作的时候必须是在热车的状态下，更换前应行驶20分钟以上，不能冷车换油。换油时要启动发动机，把各挡位从P挡到N、D、L1、L2等挡位来回拨动，然后才开始换油液。
It is worth noting that both oil change methods should be carried out when the engine is started. When changing the automatic transmission fluid, the operation must be in the hot vehicle state. The vehicle shall be driven for more than 20 minutes before replacement, and the cold vehicle is not allowed to change the oil. When changing the oil, start the engine, shift the gears from P to N, D, L1 and L2, and then start to change the oil.
误区三：无需换油
Myth 3: no need to change oil
济南自动变速箱维修厂家发现很多车主，并没有养成更换自动变速器油的意识。而更换了劣质油和不按型号换油，也会导致自动变速器“短命”。自动变速箱油经常以被忽视的形象存在，等发现的时候才知道原来成本很高，所以注意自动变速箱的维护和保养尤为重要。
Jinan automatic transmission maintenance manufacturers found that many car owners did not develop the awareness of changing automatic transmission oil. The replacement of inferior oil or not according to the model will also lead to "short life" of the automatic transmission. Automatic transmission oil often exists in the image of being ignored. When it is discovered, it is known that the original cost is very high. Therefore, it is particularly important to pay attention to the maintenance of automatic transmission.
