大家都希望自己的变速箱保持良好的工作状态，即使是坏了也希望能少一些维修费。为了减少维修费根本的办法是要把握变速箱故障的前兆，这样可以避免不必要的维修。那么自动挡变速箱出问题之前的表现是怎样的呢？下面济南自动变速箱维修人员为您解答。

We all hope that our gearbox can keep in good working condition, even if it is broken, we also hope that the maintenance fees can be reduced. The fundamental way to reduce maintenance costs is to grasp the precursors of gearbox failures, so that unnecessary maintenance can be avoided. What was the performance of the automatic transmission before it went wrong? Now Jinan automatic transmission maintenance personnel will answer for you.

1、变速箱故障灯提示、报警：这种情况一般为变速箱出现电控单元故障或机械单元故障。前者可能出现假性提示，假性提示只需对数据进行处理，对变速箱硬件没有伤害，费用限于人工费。故障灯提示有时也是偶发性的，有时会出现锁挡，特别在加速途中出现锁挡将导致车子失速，会有一定危险性。因此遇到报警提示都需尽快到维修检查。

1. Gearbox fault light prompt and alarm: This condition generally refers to the failure of electronic control unit or mechanical unit in the gearbox. The former may have false prompts, which only require professional processing of data, and will not harm the transmission hardware. The cost is limited to labor costs. The fault light prompt is also occasional, sometimes there will be a lock, especially when accelerating, which will lead to the car stalling, which will be dangerous. Therefore, in case of alarm prompt, it is necessary to go to the professional maintenance center for inspection as soon as possible.

2、打滑：踩油门，发动机转速升高，速度上不去。尤其是车子出地库、爬高架时表现明显。初期症状是偶发的。如果在驾驶习惯良好，车龄又不长的情况下，很多可能是变速箱油的问题导致的。这时候变速箱并没有损坏，一般通过换油就能解决。还有一种可能就是离合器片、制动器、活塞三者没有匹配默契而导致打滑，这种情况就应尽快找维修机构检查。

2. Slipping: When the accelerator is pressed, the engine speed will increase and the speed will not increase. Especially when the car is out of the basement and climbing overhead, it is obvious. Initial symptoms are sporadic. If the driving habits are good and the car is not old, many problems may be caused by the transmission oil. At this time, the gearbox is not damaged. It can be solved by changing the oil. Another possibility is that the clutch disc, brake and piston do not match with each other, resulting in slipping. In this case, you should find a professional maintenance organization to check as soon as possible.

3、顿挫：车子升降档时有冲击顿挫感，或在加速时有卡顿怂车的感觉。初期可能是因为电磁阀异常，不能对油压正常调整，多数是油变质了，阀道磨损致使电磁阀受损。初期只需更换电磁阀，价格不贵。若等到后期磨损更严重了，变速箱内部的杂质就会进一步产生破坏力度，导致阀芯损伤，严重的话则需要更换阀体，维修费就贵了。

3. Stuttering: The car feels bumpy when shifting up and down, or feels stuck when accelerating. At the initial stage, it may be that the solenoid valve is abnormal and the oil pressure cannot be adjusted normally. Most of the oil is deteriorated and the solenoid valve is damaged due to wear of the valve channel. At the initial stage, only the solenoid valve needs to be replaced, and the price is not expensive. If the wear becomes more serious in the later period, the impurities in the gearbox will further damage the valve core, causing serious damage. If it is serious, the valve body needs to be replaced, and the maintenance cost will be expensive.

4、换挡延迟；有些车换挡延迟是因为油变质了导致油压不足，很多情况下更换变速箱油即可解决问题。有的车则是因为天生的设计缺陷，一般十万公里后就容易出现该故障，主要原因在于机械部件如铝鼓、波浪片磨损导致油压不够，该问题需及时检查。

4. Shift delay; In some cars, the shift delay is caused by the insufficient oil pressure due to the deterioration of the oil. In many cases, the problem can be solved by changing the transmission oil. Some cars are born with design defects, which are easy to occur after 100000 km. The main reason is that the oil pressure is not enough due to the wear of mechanical parts such as aluminum drums and wave plates. This problem needs to be checked in time.

5、异响：车子开起来后出现非正常的响声，可能原因一般是变速箱内齿轮或轴承受力过大或自身材质欠佳，也有可能是一些金属部件接触面不够光滑导致，这种情况出现应及时检查维修，否则将扩大损坏面积。

5. Abnormal noise: abnormal noise occurs after the car is driven, which may be caused by excessive bearing force of gears or bearings in the gearbox or poor material of the car itself, or it may be caused by the lack of smooth contact surface of some metal parts. In this case, timely inspection and maintenance should be carried out, otherwise the damaged area will be expanded.

6、变速箱出现高温：通常在行驶过程中，仪表盘提示变速箱温度过高，只要有提示则说明温度已经达到120度以上。一种情况是变速箱内多组摩擦元件同时工作而导致高温。这种情况须停车自然降温，否则会快速损伤变速箱内摩擦元件。另一种情况就是变速箱散热器水管堵塞，无法散热，这种情况则需要维修。

6. High temperature of the transmission: usually during driving, the instrument panel prompts that the transmission temperature is too high. If there is a prompt, it indicates that the temperature has reached more than 120 degrees. In one case, multiple groups of friction elements in the gearbox work at the same time, resulting in high temperature. In this case, the vehicle must be stopped to cool down naturally, otherwise the friction elements in the gearbox will be quickly damaged. The other case is that the radiator pipe of the transmission is blocked and cannot dissipate heat, which requires maintenance.

7、挂档后发动机熄火：变矩器内单向离合器卡死，起不到单向增扭作用。这种情况一般是偶发，但需尽快到维修机构排查处理。

7. Engine stalling after gear is engaged: the one-way clutch in the torque converter is stuck, which cannot play a one-way torque increasing role. This situation usually happens occasionally, but it needs to be checked and handled by a professional maintenance organization as soon as possible.

以上我们总结了七种问题，任何一种问题在置之不理的情况下都有可能发展成多种问题。多种问题的维修费自然就被拉高了。所以说变速箱出现故障前兆要把握佳时机进行处理，有的可能通过换油就能变好，有的则需要有维修机构来处理。更多相关内容就来我们网站http://www.jnbsx.com咨询了解吧！
