变速箱是汽车重要的三大件之一，很多修理工发愁的就是修理变速箱，所以说，变速箱的保养就变得尤为重要，下面济南自动变速箱维修厂家就简单的讲一讲从挂挡是否正常能看到变速箱是否异常。

Gearbox is one of the three most important parts of automobile. Many repairmen worry about repairing the gearbox. Therefore, the maintenance of the gearbox becomes particularly important. Next, the Jinan automatic gearbox maintenance manufacturer will briefly talk about whether the gearbox is abnormal from whether the gear is normal.

挂档困难

Difficulty in engaging gear

信不信由你，仍然有不少人练习手动档技术，一脚踩刹车，一脚踩离合，手握换档杆，而且乐此不彼，心甘情愿。尽管手动档操作貌似简单，手动变速箱仍然有可能出错。常见问题是当你踩下离合器踏板时，并试图移动换档杆时，变速箱无法挂上档位。这种情况可能发生在从停止进入一档位时，也有可能在往上换档或者往下换档的时候发生。通常原因包括变速箱液体过低、变速箱液黏度不对(流体的黏度过厚)，或换档缆线或离合器联动需要调整。

Believe it or not, there are still many people who practice manual transmission technology, step on the brake with one foot, step on the clutch with one foot, and hold the shift lever with one foot. Although the manual gear operation seems simple, the manual transmission may still make mistakes. A common problem is that when you step on the clutch pedal and try to move the shift lever, the transmission cannot shift up. This may happen when you shift from stop to first gear, or when you shift up or down. Common reasons include low transmission fluid, incorrect viscosity of transmission fluid (too thick viscosity of fluid), or adjustment of shift cable or clutch linkage.

自动换档时间过长或者过短

Autoshift time is too long or too short

一般自动变速箱都是有特定的换档转速和车速，如果发现换档时间突然过长或者过短，这就意味着变速箱的传动比不成比例了，同时会感觉发动机的转速过高，情况更甚者是变速箱不进行换档，这都说明变速箱出了问题。

Generally, the automatic transmission has a specific shift speed and speed. If the shift time is suddenly too long or too short, it means that the transmission ratio of the transmission is disproportionate. At the same time, it will feel that the engine speed is too high. What's more, the transmission does not shift, which indicates that there is a problem with the transmission.

主动变速器不能升档

Active transmission fails to upshift

行进途中主动变速器一向坚持在1档，不能升2档及高速档；行进行进中主动变速箱能够升入2档，但不能升入3档和超速档。应查看调整节气门拉线和节气门方位传感器；查看车速传感器；查看档位开关信号。丈量调速器油压，假定车速添加后调速器油压为0或很低，阐明调速器有缺陷或漏油。假定控制体系无缺陷，应拆检主动变速器，查看换档实行组件是不是打滑，用压缩空气查看各聚散器、制动器油缸或活塞有无走漏。

On the way, the active transmission always sticks to the first gear, and cannot shift up to the second gear or the high gear; The active transmission can shift into the second gear, but cannot shift into the third gear and overdrive gear. Check and adjust the throttle cable and throttle position sensor; Check the speed sensor; Check the gear switch signal. Measure the oil pressure of the governor. Assume that the oil pressure of the governor is 0 or very low after the vehicle speed is increased. Explain that the governor has defects or oil leakage. Assuming that the control system is free of defects, the active transmission should be disassembled and inspected to see if the shift implementation component is slipping, and the condenser, brake oil cylinder or piston should be checked with compressed air for leakage.

挂档发动机熄火

The engine stalls in gear

在启动汽车后，将换档杆由P或N位换入其他位置(P或R时)，发动机熄火，或者在行驶过程中踩制动停车发动机熄火（不带自动启停功能）。对于变速箱来说可能锁止电磁阀损坏或锁止控制阀发卡造成的。如果数次挂档造成发动机熄火，这是要查看入档冲击是不是很大，如果比较大，就要打救援电话。不然多次尝试，本来只是换个阀体的事，后却变成了变速箱大修。

After starting the car, change the shift lever from P or N to another position (P or R), and the engine will stop, or press the brake to stop the engine during driving (without automatic start and stop function). For the transmission, it may be caused by the damage of the locking solenoid valve or the jamming of the locking control valve. If the engine stalls due to several times of gear engagement, it is necessary to check whether the impact of gear engagement is large. If it is large, call a rescue phone. Otherwise, after many attempts, it was only a matter of changing the valve body, but later it turned into an overhaul of the gearbox.

跳档

Skip gear

在正常行驶的情况下，变速箱一般处于正常的行驶档位。但是，如果变速箱齿轮自动滑档，汽车便会发生跳档的情况，这种情况就要特别注意了。造成这种情况的原因一般是因为变速箱的齿轮或者其他部件磨损，当然也有可能是其他原因，例如变速杆传动部件松动，但这些情况并不常见。的方法也是去维修店维修。

Under normal driving conditions, the transmission is generally in the normal driving gear. However, if the transmission gear automatically slides, the car will skip gears. This situation needs special attention. This is usually caused by the wear of gears or other parts of the transmission, but it may also be caused by other reasons, such as loose transmission parts of the transmission lever, but these conditions are not common. The only solution is to go to the maintenance shop for maintenance.

变速箱是汽车脆弱的部件之一，一旦变速箱出问题，比发动机出问题还严重，还难修，所以以上的相关征兆很重要，一般出现这6个现象，就要注意检查变速箱了。更多相关内容就来我们网站http://www.jnbsx.com咨询了解吧！

The gearbox is one of the vulnerable parts of the car. Once the gearbox has a problem, it is more serious than the engine, and it is difficult to repair. Therefore, the above symptoms are very important. Generally, if these six phenomena occur, it is necessary to pay attention to the inspection of the gearbox.
