变速箱是出现了不正常的异响，车主都要去重视它，那是需要维修的。当遇到变速箱出现异响，长时间不去维修，就很有可能会对变速箱造成损坏。下面
济南自动变速箱维修人员就给大家分析一下自动变速箱异常响声故障的排除方式。
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.故障情况
1. Fault conditions
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。
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
一般来说，原因有如下几个方面：
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 low or high oil level of automatic transmission;
（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 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）行星齿轮机构异响；
(3) Abnormal noise of planetary gear mechanism;
（4）换档执行元件异响。
(4) The shift actuating element makes abnormal noise.
3.方法
3. Solutions
（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 automatic transmission oil level. If it is too high or too low, it shall 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 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 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。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。
(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.jnbsx.com Consult!
