自从汽车发明以来，每年都会有大量的变速箱故障来源于操作不当和保养不到位造成的。长时间未更换自动变速箱油会产生怎样的后果？下面济南自动变速箱维修人员为您讲解。

Since the invention of the automobile, a large number of gearbox failures are caused by improper operation and inadequate maintenance every year. What will happen if the ATF is not changed for a long time? Next, Jinan automatic transmission maintenance personnel will explain to you.

1.自动变速箱工作时依靠液力传动，长时间运转会产生大量的热能，若散热不良易导致变速箱过热，高温造成变速箱油液在一定时期内变质。

1. The automatic transmission relies on hydraulic transmission when it works. Long-term operation will generate a large amount of heat energy. Poor heat dissipation will easily cause the transmission to overheat, and high temperature will cause the transmission oil to deteriorate within a certain period of time.

2.城市道路拥堵、雾霾、粉尘等空气污染导致比较恶劣的行车环境。自动变速箱受温度、载荷等因素的影响，工作要求条件苛刻，脏污的变速箱油液更易加剧自动档内部元件之间的磨损。

2. Urban road congestion, haze, dust and other air pollution cause relatively bad driving environment. Affected by temperature, load and other factors, the automatic transmission requires harsh working conditions. Dirty transmission oil is more likely to aggravate the wear between the internal components of the automatic transmission.

3.随着车辆行驶里程的增加，自动变速箱本身的数据参数在不断发生改变。工作元件之间的配合间隙、摩擦系数、系统压力等因素的变化，均会影响自动变速箱正常运转，若不定期检测和保养，则会造成自动变速箱早期损坏。

3. With the increase of vehicle mileage, the data parameters of the automatic transmission itself are constantly changing. The change of the fit clearance, friction coefficient, system pressure and other factors between the working elements will affect the normal operation of the automatic transmission. If the automatic transmission is not regularly inspected and maintained, it will cause early damage to the automatic transmission.

4.其他外部因素的影响，变速箱进水、传感器信号异常、油底壳托底变形、密封件老化漏油等，都可能造成自动档工作不正常，若不及时检查保养，同样也会出现故障。

4. The influence of other external factors, such as water ingress into the transmission, abnormal sensor signal, deformation of the bottom of the oil pan, aging and oil leakage of the seals, may cause abnormal operation of the automatic gear. If it is not checked and maintained in time, it will also cause failure.

还有一些不当的操作习惯，如猛轰油门、急踩刹车、空挡滑行等，不当操作会加剧内部工作元件之间的磨损，产生的铁屑、粉沫等杂质随着油液的流动，可能造成阀体卡滞、油道堵塞等故障，这种情况好的办法就是更换变速箱油液、清除杂质，确保内部清洁状况良好。更多相关内容就来我们网站http://www.jnbsx.com咨询！

There are also some improper operating habits, such as slamming the accelerator, slamming the brake, sliding in neutral gear, etc. Improper operation will aggravate the wear between the internal working elements, and the generated iron filings, powder and other impurities may cause the valve block, oil channel blockage and other faults along with the flow of the oil. The good way for this situation is to replace the transmission oil, remove the impurities, and ensure that the internal cleaning is in good condition.
