关于变速箱的重要性，相信很多车主都明白，不需要再去论述。变速箱不容易出现问题，但是如果一旦出现故障，就比较麻烦。当变速箱故障发生时该怎么办呢，别着急，接下来我们就为大家介绍变速箱故障诊断分析，解决各位车主的后顾之忧。
As for the importance of gearboxes, I believe many owners understand that there is no need to discuss them again. Gearboxes are not prone to problems, but if they fail, they will be more troublesome. When the gearbox failure should be done, do not worry, then we will introduce the gearbox fault diagnosis analysis for you, to solve the worries of the owners of the car.
变速箱故障诊断分析
Fault diagnosis and analysis of gearbox
1、挂档难、顿挫感
1. It is difficult to file a file and a feeling of frustration
起步或行驶过程中，挂、摘、换挡发涩、费力，好像被什么卡了一下，有耸车、震动、顿挫感，有时凉车易挂挡，热车难挂挡，带有很多不舒适性;原因是变速箱内相关齿轮等部件得不到足够的润滑，且形不成持久的润滑膜，使得部件无法流畅工作。
In the process of starting or driving, hanging, picking and shifting are astringent and laborious. It seems to be stuck with something, such as shrug, vibration, and setback, sometimes the cool car is easy to hang up, the hot car is difficult to hang up, and it has a lot of discomfort. The reason is that the gear and other parts in the gearbox cannot be lubricated enough, and the shape is not a durable lubricating film. The parts do not work smoothly.
2、自动挡闯挡、冲击感
2, automatic blocking, impact feeling
起步没动力，低速或中速行驶时车子有明显耸车和顿挫感，同时仪表盘上的转速表针上下浮动;中高速行驶过程中急踩油门踏板的情况下，车子打滑，转速表针急速上升和有明显的冲击感;由P档挂入R档和D档，车子有明显的冲击感、闯档。
The car has obvious shrug and frustration at low speed or medium speed, while the speed surface on the dashboard is floating up and down; in the middle and high speed process, the car skid, the speed needle rises rapidly and has a significant impact; the car has an obvious impact on the R and D gear from the P gear. To break the file.

原因可能是变速箱内出现杂质，在阀体形成堵塞，导致阀体上下运动不畅，无法顺序实现对油压的调节，导致闯挡、换挡冲击故障。
The cause may be the appearance of impurities in the gearbox, forming a blockage in the valve body, causing the valve body to move down and down, and can not adjust the oil pressure in order, leading to the break and shift impact failure.
3、变速箱异响、噪音大
3. Abnormal noise and loud noise of gearbox
车子在怠速时或行驶以及高负荷行驶过程中，听到变速器有异响，甚至很大的噪音，在挂换挡时有无节奏、沉闷的响声。造成上述现象的主要原因是变速箱内脏污，轴承、齿轮等部件出现磨损或严重磨损，或齿轮侧面有损坏。
When the car is in the process of idle speed or driving and high load, it is heard that the transmission has different noise, even a lot of noise, and there is no rhythm and dreary noise in the gear shift. The main causes of the above phenomena are the internal fouling of the gearbox, wear or serious wear of bearings, gears and other components, or damage to the side of the gears.
4、变速箱温度过高
4. The temperature of the gearbox is too high
行驶过程中电脑显示报警：变速箱温度过高;或行驶一段后自己感觉变速箱过热，甚至烫手。这应该是变速箱内部经常超负荷运转，无法有效控温造成的。
In the course of driving, the computer display alarm: the temperature of the transmission is too high; or after a period of driving, I feel overheated transmission, or even hot. This should be caused by the overload operation of the gearbox and the failure to control the temperature effectively.
5、车子发生打滑或冲击
5. A car is skidding or impacting
如果挂上D档或R档车子不走，或者车子反应很迟缓后冲击，或者发动机转速很高但车速却很慢，就意味着变速箱内部的机械传动部分出了问题。
If the D or R gear does not go, or the car's reaction is slow, or the engine speed is very high, but the speed is slow, it means the mechanical transmission part of the gearbox is out of problem.
6、变速箱体内产生异味
6. The odor produced in the gearbox
变速箱体是靠液压油来工作的，当油温过高时，会产生一些燃烧，这些异味会传出来，这就说明变速箱体内的某些执行部件工作不正常。
The gearbox is operated by hydraulic oil. When the oil temperature is too high, some burning will be produced. These peculiar smell will be passed out. This shows that some of the execution parts in the gearbox are not working properly.
7、引擎空转
7. Engine empty
引擎空转一般发生在两种情况：
Engine turnover is generally in two cases:
(1)、在车辆在平稳种突然出现引擎空转的现象，在车速慢下来有恢复正常，这种情况一般说明变速箱在短的时间内突然从高档位降为低档位，问题有可能处在控制系统或者散热系统上，变速箱本身没有问题。
(1), in the vehicle in a stable type of sudden emergence of the phenomenon of engine empty, the speed slowed down to normal, this situation generally shows that the gearbox in a short time suddenly from high level down to low level, the problem may be in the control system or heat dissipation system, the gearbox itself has no problem.
(2)、在加速的过程中或者在换档的过程中出现短暂的打滑空转现象，直观的感觉是后者没有前者那么厉害，实际上确实恰恰相反，后者的问题多半处在变速箱内的离合器等相关环节上，处理起来出要变速箱彻底解体检修，时间成本消耗都要比前者多出许多。
(2), in the process of acceleration or in the process of shift, there is a short skidding phenomenon. The intuition is that the latter is not as strong as the former. In fact, it is really the opposite. The latter is mostly in the clutch and other related links in the gearbox, and the transmission is completely disintegrated and overhauled. The cost is much more than the former.
8、汽车不能行驶
8, the car can't drive
无论将换挡杆位于倒挡还是前进挡，汽车都不能行驶;又或者冷车起动后汽车能行驶一小段路程，但热车状态下汽车不能行驶。遇到这样的情况可能是：1、自动变速箱漏油严重，严重缺油;2、换挡杆和手动阀摇臂之间的连杆或拉索松脱，手动阀保持在空挡或停车挡位置;3、进油滤网堵塞;4、主油路严重泄漏;5、油泵损坏。建议去4S店维修保养。
Whether the shift lever is in the reverse or the forward gear, the car can't drive, or the car can run for a short distance after the cold car starts, but the car can't drive under the hot car. The situation may be: 1, the automatic transmission oil leakage serious, serious oil shortage; 2, the shift lever and the manual valve rocker between the connecting rod or cable loose, the manual valve remains in the air or parking gear position; 3, oil filter screen blockage; 4, main oil road leakage; 5, oil pump damage. It is suggested to go to 4S shop for maintenance.
变速箱误判的危害
The harm of miscarriage of gear box
自动变速箱系统跟发动机系统及ABS系统等有紧密的通信，电脑系统牵扯面非常复杂，另外机械方面精度非常高。所以变速箱系统出现故障可能涉及多方面原因，一旦出现故障，建议车主到汽车维修店，由经验丰富的技师进行诊断。
Automatic transmission system has close communication with engine system and ABS system, the computer system is very complicated, and the mechanical precision is very high. Therefore, the failure of the gearbox system may involve many reasons. Once the failure occurs, it is suggested that the owner of the vehicle go to a professional car repair shop and be diagnosed by an experienced professional technician.
