异常响声在维修行业称为异响。在汽车运转过程中，常见自动变速器内有异响声、汽车行驶中自动变速器有异响，停车挂档后异响消失。原因有什么呢？
济南自动变速箱维修厂家人员立即附和，对原因主要有四个：
Abnormal noise is called abnormal noise in the maintenance industry. During the operation of a car, there is a common abnormal noise inside the automatic transmission. The automatic transmission makes a abnormal noise while the car is in motion, and the abnormal noise disappears after parking and shifting gears. What are the reasons for this? The personnel from the Jinan automatic transmission maintenance manufacturer immediately agreed, and there are four main reasons for this:
1、油泵因磨损过甚或自动变速器油面高度过低、过高而产生异响;
1. The oil pump may produce abnormal noise due to excessive wear or even low or high automatic transmission oil level;
2、液力变矩器因锁止离合器、导轮单向超越离合器等损坏而产生异响;
2. The Torque converter makes abnormal noise due to the damage of the lock up clutch and the one-way overrunning clutch of the stator;
3、行星齿轮机构异响;
3. Abnormal noise from planetary gear mechanism;
4、换档执行元件异响。
4. Abnormal noise from the shift actuator.
相应的解决方法：
Corresponding solutions:
1、检查自动变速器油油面高度。若太高或太低，应调整至正确高度。
1. Check the oil level of the automatic transmission. If it is too high or too low, it should be adjusted to the correct height.
2、应举升器将汽车升起，起动发动机，在空档、档、倒档等状态下检查自动变速器产生异响的部位和时刻。
2. Lift the car with a hoist, start the engine, and check the location and timing of abnormal noise generated by the automatic transmission in neutral, gear, reverse, and other states.
3、若在任何档位下自动变速器前部始终有连续的异响，通常为油泵或液力变矩器异响，对此，应拆检自动变速器，检查油泵有无磨损、液力变矩器内有无大量摩擦粉末。如有异常，应更换油泵或液力变矩器。
3. If there is a continuous abnormal sound at the front of the automatic transmission at any gear, it is usually the abnormal sound of the oil pump or the Torque converter. For this, the automatic transmission should be disassembled and inspected to check whether the oil pump is worn and whether there is a large amount of friction powder in the Torque converter. In case of any abnormality, replace the oil pump or Torque converter.
4、若自动变速器只有在行驶中才有异响，空档时无异响，则为行星齿轮机构异响。对此，应分解自动变速器，检查行星齿轮机构各个零件有无磨损痕迹、齿轮有无断裂，单向超越离合器有无磨损、卡滞，轴承或止推垫片有无损坏。如有异常，应予以更换。
4. If the automatic transmission only makes abnormal noises while driving and there is no abnormal noise when in neutral, it is a planetary gear mechanism abnormal noise. In this regard, the automatic transmission should be disassembled and checked for signs of wear on various parts of the planetary gear mechanism, gear breakage, one-way overrunning clutch wear and jamming, and bearings or thrust washers for damage. If there are any abnormalities, they should be replaced.
自动变速箱一旦出现故障，车主要及时将其送修，如出现故障时，车主并未在意继续使用车辆，可能会导致车辆不走车，甚至整个变速箱报废。因此，变速箱一旦出现故障，一定要及时将其送往变速箱维修站点进行维修，以免因小失大。更多相关内容就来我这里

Once an automatic transmission malfunctions, the vehicle owner should promptly send it for repair. If a malfunction occurs, the vehicle owner may not pay attention to continuing to use the vehicle, which may ultimately result in the vehicle not running and even the entire transmission being scrapped. Therefore, once the gearbox malfunctions, it is necessary to promptly send it to a professional gearbox maintenance station for repair, in order to avoid wasting time.
