由于操作简单方便，自动变速器逐渐成为购车的。变速箱维修起步、怠速停车、低速或高速行驶、加速、减速、爬坡和倒车等，这就要求汽车的驱动力和车速能在相当大的范围内变化，而目前广泛采用的活塞式发动机的输出转矩和转速变化范围较小。为了适应经常变化的行驶条件，同时使发动机在有利的工况下(功率较高、油耗较低)工作，在传动系统中设置了变速器。自动变速箱维修自动变速器的核心在实现自动换挡。所谓自动换挡是指汽车在行驶的过程中，驾驶员按行驶过程的需要操控加速踏板（油门踏板），自动变速器即可根据发动机负荷和汽车的运行工况，自动换入不同挡位工作。
Because of its simple and convenient operation, automatic transmission has gradually become the first choice for car purchase. Transmission maintenance start, idle parking, low or high speed driving, acceleration, deceleration, climbing and reversing, etc., which requires the driving force and speed of the car to change in a considerable range, while the widely used piston engine has a smaller range of output torque and speed. In order to adapt to the frequently changing driving conditions and make the engine work under favorable working conditions (high power and low fuel consumption), a transmission is set up in the transmission system. Automatic transmission maintenance the core of automatic transmission is to realize automatic shift. The so-called automatic gear shifting refers to that in the process of driving, the driver controls the accelerator pedal (accelerator pedal) according to the needs of the driving process, and the automatic transmission can automatically shift into different gears according to the engine load and the operating conditions of the car.
一、常见的故障是在行驶时出现弱速、低速或中速行驶时，汽车有明显的换档和挫折，并在仪表盘的滑轨上出现限速针；在中高速快速加油行驶时，出现空转现象，而且测速针快速上升，撞击感清晰；此外，汽车在悬挂或移位时有明显的撞击感，甚至有时会被关闭或延迟。这些症状表明自动变速器出现故障。
1、 The common fault is that when driving at weak speed, low speed or medium speed, the car has obvious shift and setback, and the speed limit needle appears on the slide rail of the instrument panel; when driving at medium high speed and high speed, there is idling phenomenon, and the speed measuring needle rises rapidly, and the impact feeling is clear; in addition, the car has obvious impact feeling when hanging or shifting, and sometimes it is closed Or delay. These symptoms indicate an automatic transmission failure.
二、常见故障有异常噪声：在怠速、驱动和高负载换档过程中，自动变速箱中出现异常噪声或燃油喷射现象，这也意味着变速箱有故障。
2、 Common faults include abnormal noise: abnormal noise or fuel injection in the automatic transmission during idling, driving and high load shifting, which also means that the gearbox is faulty.
三、变速箱油都有异味，其中大部分都是由自动变速箱的高温引起的。自动变速器使用液压油。当外部散热器出现问题时，油温会过高。导致变速箱油液变质。建议业主定期清洁散热器并更换防冻液。
3、 Transmission oil has peculiar smell, most of which is caused by high temperature of automatic transmission. The automatic transmission uses hydraulic oil. When there is a problem with the external radiator, the oil temperature will be too high. This causes the transmission fluid to deteriorate. It is recommended that the owner clean the radiator regularly and replace the antifreeze.
四、仪表指示灯报警：在车辆行驶中，仪表板上的自动变速器故障指示灯闪烁，也是变速器故障的预警信号。
4、 Instrument indicator warning: when the vehicle is running, the automatic transmission fault indicator on the instrument panel flashes, which is also the warning signal of transmission failure.
五、油溶液为乳白色：定期检查自动变速器油。如果发现油是乳白色的，水箱可能受损或输水被淹没。
5、 The oil solution is milky white: check the automatic transmission oil regularly. If the oil is found to be milky white, the tank may be damaged or the water may be flooded.
六、档变速箱油泄漏：通常应注意停车地面是否有油污，在保养车辆时应注意检查齿轮箱油底壳部分漏油现象，如有及时处理，应避免齿轮箱油不足，使齿轮箱工作不正常。
6、 Gear box oil leakage: generally, attention should be paid to whether there is oil pollution on the parking ground. When maintaining the vehicle, attention should be paid to checking the oil leakage of the gearbox oil pan. If there is any timely treatment, the gearbox oil shortage should be avoided to make the gearbox work abnormally.
七、错误的变速箱油：
7、 Wrong transmission oil:
自动变速箱是一个非常精确的零件。不同的变速箱由于其工作原理不同，对油品的要求也不同。因此，必须严格按照制造商的标准更换特殊的油产品。
The automatic transmission is a very precise part. Different gearboxes have different requirements for oil products due to their different working principles. Therefore, special oil products must be replaced in strict accordance with the manufacturer's standards.
目前市场上有被称为“通用油”的通用油产品。有些客户不按照制造商要求的型号更换所谓的“一般”变速箱油，因为低质量的石油产品价格低廉。更换这些石油产品后，在传动系统中发生撞击或碰撞的机会显著增加。同时，传动在保护不良的情况下长时间工作，容易产生额外的老化和磨损。这使得变速器的使用寿命迅速缩短，大大增加了后续维护和维修的成本。因此，不建议使用通用传递油。
At present, there are general oil products called "general oil" on the market. Some customers do not change the so-called "normal" transmission oil according to the model required by the manufacturer because low-quality petroleum products are cheap. After replacing these petroleum products, there is a significant increase in the chance of collision or collision in the transmission system. At the same time, when the transmission works for a long time under the condition of poor protection, it is easy to produce additional aging and wear. This makes the service life of the transmission shorten rapidly, greatly increasing the cost of subsequent maintenance and repair. Therefore, it is not recommended to use universal transfer oil.
综上所述，自动变速箱常见的故障有：行驶中的碰撞、撞车现象、换挡冲击、熄火、车辆打滑、无法运行、启动无力甚至无法启动、噪音异常、温度过高等。
To sum up, the common faults of automatic transmission are: collision during driving, collision phenomenon, shift impact, flameout, vehicle skid, unable to run, weak or even unable to start, abnormal noise and high temperature.
