變速箱是出現了不正常的異響，車主都要去重視它，那是需要維修的。當遇到變速箱出現異響，長時間不去維修，就很有可能會對變速箱造成損壞。下面
濟南自動變速箱維修人員就給大家分析一下自動變速箱異常響聲故障的排除方式。
The gearbox makes an abnormal noise. The owners should pay attention to it. It needs to be repaired. If the gearbox makes abnormal noise and does not repair it for a long time, the gearbox may be damaged. Next, Jinan automatic transmission maintenance personnel will analyze the troubleshooting methods for the abnormal noise of automatic transmission.
1.故障情況
1. Fault conditions
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。
Abnormal noise is called abnormal noise in the maintenance industry. During the operation of the car, it is common for the automatic gearbox to make abnormal noise, and the automatic gearbox to make abnormal noise while the car is driving. The abnormal noise disappears after the car is stopped and put into gear.
2.可能原因
2. Possible causes
一般來說，原因有如下幾個方面：
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 low or high oil level of automatic transmission;
（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 hydraulic 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 of planetary gear mechanism;
（4）換檔執行元件異響。
(4) The shift actuating element makes abnormal noise.
3.解決方法
3. Solutions
（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 automatic transmission oil level. If it is too high or too low, it shall 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 lifter, start the engine, and check the position and time of abnormal noise generated by the automatic transmission in neutral, forward gear, reverse gear, etc;
（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 noise at the front of the automatic transmission at any gear, it is usually the abnormal noise of the oil pump or hydraulic 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 hydraulic torque converter. If abnormal, replace the oil pump or hydraulic 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。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。
(4) If the automatic transmission has abnormal noise only during driving, and there is no abnormal noise during neutral, it is planetary gear mechanism abnormal noise. In this regard, the automatic transmission shall be disassembled, and each part of the planetary gear mechanism shall be checked for wear marks, gear breakage, one-way overrunning clutch wear, seizure, and bearing or thrust gasket damage. If there is any abnormality, replace it.
The troubleshooting method for the abnormal noise of the automatic transmission is as explained above. If you have any questions or needs, please come to our website http://www.ihudie.cn Consult!
