异常响声在维修行业称为异响。在汽车运转过程中，常见自动变速箱内有异响声、汽车行驶中自动变速箱有异响，停车挂档后异响消失。
山东变速箱维修人员认为，一般来说，原因有如下几个方面：
Abnormal noise is called abnormal noise in the maintenance industry. During the operation of the car, there is a common abnormal noise in the automatic transmission, and the abnormal noise in the automatic transmission disappears after parking and shifting. Shandong gearbox maintenance personnel believe that generally speaking, the reasons are as follows:
（1）油泵因磨损过甚或自动变速箱油面高度过低、过高而产生异响；
(1) The oil pump makes abnormal noise due to excessive wear or the Automatic transmission fluid oil level is too low or too high;
（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.
方法：
Solution:
（1）检查自动变速箱油油面高度。若太高或太低，应调整正确高度；
(1) Check the oil level of Automatic transmission fluid. 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、前进档、倒档等状态下检查自动变速箱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, forward, reverse, and other states;
（3）若在任何档位下自动变速箱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，应拆检自动变速箱，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）若自动变速箱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。
(4) If the automatic transmission only makes abnormal noise during driving and there is no abnormal noise in neutral, it is a planetary gear mechanism abnormal noise.
对此，应分解自动变速箱，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。更多相关事项就来我们网站

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. For more related matters, come to our website http://www.jnbsx.com Consult!
