異常響聲在維修行業稱為異響。在汽車運轉過程中，常見自動變速箱內有異響聲、汽車行駛中自動變速箱有異響，停車掛檔后異響消失。
山東變速箱維修人員認為，一般來說，原因有如下幾個方面：
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）油泵因磨損過甚或自動變速箱油面高度過低、過高而產生異響；
(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）液力變矩器因鎖止離合器、導輪單向超越離合器等損壞而產生異響；
(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）行星齒輪機構異響；
(3) Abnormal noise from planetary gear mechanism;
（4）換檔執行元件異響。
(4) Abnormal noise from the shift actuator.
解決方法：
Solution:
（1）檢查自動變速箱油油面高度。若太高或太低，應調整至正確高度；
(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）應舉升器將汽車升起，起動發動機，在空檔、前進檔、倒檔等狀態下檢查自動變速箱產生異響的部位和時刻；
(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）若在任何檔位下自動變速箱前部始終有連續的異響，通常為油泵或液力變矩器異響，對此，應拆檢自動變速箱，檢查油泵有無磨損、液力變矩器內有無大量摩擦粉末。如有異常，應更換油泵或液力變矩器；
(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）若自動變速箱只有在行駛中才有異響，空檔時無異響，則為行星齒輪機構異響。
(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.
對此，應分解自動變速箱，檢查行星齒輪機構各個零件有無磨損痕跡、齒輪有無斷裂，單向超越離合器有無磨損、卡滯，軸承或止推墊片有無損壞。如有異常，應予以更換。更多相關事項就來我們網站

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://m.mmolords.cn Consult!
