对自动变速箱故障诊断分析的6种现象，为了让大家更方便更省时间的了解，下面
山东变速箱维修人员为您整理内容。
For the six phenomena of automatic transmission fault diagnosis and analysis, in order to make it easier and save time for everyone to understand, the following Shandong transmission maintenance personnel will sort out the contents for you.
1.挂档难，顿挫；
1. It is difficult to engage the gear and falters;
起动或行驶时，挂、摘、换挡发涩，费力，仿佛被什么卡住了，有耸车、震动、顿挫的感觉，有时凉车容易挂挡，热车难挂挡，带有许多不舒服；原因是变速箱内相关齿轮等部件没有得到足够的润滑，也没有形成持久的润滑膜，使部件不能顺利工作。有的变速箱如AMT本身就有类似现象，稍有顿挫，这是产品本身的问题，不严重的话就是正常现象。其它变速箱可先通过换油试着解决。
When starting or driving, the gears are jerky and hard to shift, as if they are stuck by something. There is a feeling of shrug, vibration and frustration. Sometimes it is easier to shift gears when the car is cold, but it is difficult to shift gears when the car is hot, with a lot of discomfort; The reason is that the relevant gears and other components in the gearbox are not lubricated enough, and no lasting lubricating film is formed, which makes the components unable to work smoothly. Some transmissions, such as AMT itself, have similar phenomena, and a slight setback. This is a problem with the product itself. If it is not serious, it is normal. Other transmissions can be solved by changing the oil first.
2.自动挡入挡，冲击感；
2. Automatic shifting, impact feeling;
起动无动力，低速或中速行驶时车辆有明显的耸立和挫折感，同时仪表盘上的转速表针上下浮动；中高速行驶时急踩油门踏板时，车辆打滑，转速表针急速上升，有明显的冲击感；从P档挂到R档和D档，车辆有明显的冲击感，闯档。
There is no power when starting. When driving at low or medium speed, the vehicle has obvious sense of standing up and frustration. At the same time, the tachometer needle on the instrument panel floats up and down; When stepping on the accelerator pedal at medium and high speeds, the vehicle skids, and the tachometer needle rises rapidly with a clear sense of impact; When shifting from P gear to R gear and D gear, the vehicle has a clear sense of impact.
原因可能是变速箱内有杂质，阀体堵塞，导致阀体上下运动不畅，无法顺序调节油压，导致冲击和换挡冲击故障。
The reason may be that there are impurities in the gearbox and the valve body is blocked, which causes the valve body to move up and down unsmooth, and the oil pressure cannot be adjusted in sequence, leading to shock and shift shock failures.
3.变速箱异响，噪音大；
3. The gearbox makes abnormal noise;
汽车在怠速、行驶和高负荷行驶过程中，听到变速器有异常噪音，甚至有很大的噪音，挂换挡时有无节奏、无聊的噪音。造成上述现象的主要原因是变速箱内脏、轴承、齿轮等部件磨损或严重磨损，或齿轮侧面损坏。
During idling, driving and high load driving, the car hears abnormal noise from the transmission, even loud noise, and whether there is rhythmic and boring noise when shifting gears. The main reasons for the above phenomena are the wear or severe wear of the internal parts of the gearbox, bearings, gears and other components, or the damage of the gear side.
4.变速箱温度过高；
4. The gearbox temperature is too high;
电脑在行驶过程中显示报警：变速箱温度过高；或者行驶一段时间后自己觉得变速箱过热，甚至烫手。它应该是由于变速箱内经常超负荷运转，不能有效控制温度所致。
The computer displays an alarm during driving: the gearbox temperature is too high; Or after driving for a while, I think the gearbox is overheated, even hot. It should be caused by the frequent overload operation of the gearbox and the failure to effectively control the temperature.
5.汽车打滑或冲击；
5. Vehicle skidding or impact;
如果D档或R档车不行，或者车反应缓慢，或者发动机转速高但速度慢，说明变速箱内的机械传动部分有问题。
If the D or R gear car is not working, or the car responds slowly, or the engine speed is high but slow, it indicates that there is a problem with the mechanical transmission in the gearbox.
6.变速箱产生异味；
6. The gearbox has peculiar smell;
齿轮箱是用液压油工作的，当油温过高时，会产生一些燃烧，这些气味会传出，这说明齿轮箱内的某些执行部件工作异常。
The gearbox works with hydraulic oil. When the oil temperature is too high, some combustion will occur and these smells will be sent out, which indicates that some executive parts in the gearbox are abnormal.
