自动变速箱顿挫的原因及解决方法主要包括以下几点：

　　The reasons and solutions for automatic transmission jerking mainly include the following points:

　　原因

　　reason

　　油温过高：油温过高会影响变速箱的正常工作，导致顿挫。

　　Excessive oil temperature: Excessive oil temperature can affect the normal operation of the gearbox, leading to jerking.

　　脏污与杂质堵塞阀体：阀体内部出现顽固的污垢和杂质堵塞，会导致无法调节油压，进而形成顿挫、冲击等问题。

　　Dirt and impurities blocking the valve body: Stubborn dirt and impurities blocking the inside of the valve body can cause the inability to adjust the oil pressure, resulting in problems such as jerking and impact.

　　电磁阀损坏：电磁阀出问题，会影响变速箱的换挡逻辑和顺畅度。

　　Damaged solenoid valve: Problems with the solenoid valve can affect the shifting logic and smoothness of the gearbox.

　　变速箱内部离合器泄压：离合器压力不足，无法正常传递动力，就容易产生顿挫。

　　Internal clutch pressure relief in the gearbox: Insufficient clutch pressure prevents normal power transmission, which can easily lead to jerking.

　　变速箱油路发卡不顺畅：油路发卡不顺畅或磨损，油液流动受阻，会造成顿挫。

　　The transmission oil circuit is not smooth: The oil circuit is not smooth or worn, and the flow of oil is blocked, which can cause jerking.

　　变速箱油未添加到标准值：油液量不合适，无法为变速箱提供良好的润滑和工作条件。

　　The transmission oil has not been added to the standard value: the oil level is not appropriate, which cannot provide good lubrication and working conditions for the transmission.

　　自动变速箱调教标定的控制程序与磨损后的硬件状态不匹配：原本的控制程序是按照全新的自动变速箱编写的，硬件磨损后就可能出现顿挫。

　　The control program for automatic transmission tuning and calibration does not match the hardware state after wear and tear: the original control program was written based on a brand new automatic transmission, and hardware wear may cause jolts.

　　检查并更换变速箱油：

　　Check and replace the transmission oil:

　　定期检查和更换变速箱油，确保油液的清洁和正常量。建议每行驶2年或4万公里后更换一次。

　　Regularly check and replace the transmission oil to ensure its cleanliness and normal quantity. It is recommended to replace it every 2 years or 40000 kilometers after driving.

　　如果发现变速箱油中有铁屑等物质，可能说明自动变速器中制动器和离合器的摩擦片磨损，需及时更换变速箱油。

　　If iron filings or other substances are found in the transmission oil, it may indicate that the friction plates of the brake and clutch in the automatic transmission are worn, and the transmission oil needs to be replaced in a timely manner.

　　检查变速箱油尺，确保变速箱油添加到标准刻度。如果变速箱油少了或者多了都会导致顿挫故障出现。

　　Check the transmission oil dipstick to ensure that the transmission oil is added to the standard mark. If there is too little or too much transmission oil, it can cause jerking faults.

　　清洗阀体：

　　Cleaning the valve body:

　　如果发现阀体内部出现了污垢和杂质，请及时联系专业的汽车维修人员进行清洗。

　　If dirt and impurities are found inside the valve body, please contact professional car maintenance personnel for cleaning in a timely manner.

　　检查并维修电磁阀：

　　Check and repair the solenoid valve:

　　电磁阀损坏时，应及时到4S店或者汽车维修店进行检查和维修。

　　When the solenoid valve is damaged, it should be promptly inspected and repaired at a 4S store or car repair shop.

　　检查并修理变速箱内部离合器：

　　Check and repair the internal clutch of the gearbox:

　　如果变速箱内部离合器泄压，应检查离合器是否损坏，并进行修理。

　　If the clutch inside the gearbox is depressurized, check whether the clutch is damaged and repair it.

　　检查并更换油泵：

　　Check and replace the oil pump:

　　油泵故障是导致自动变速箱顿挫的一个常见原因，发现油泵有问题时，应及时检查和维修。

　　Oil pump failure is a common cause of jerking in automatic transmissions. When a problem is found with the oil pump, it should be promptly inspected and repaired.

　　调整或更换控制程序：

　　Adjust or replace the control program:

　　如果自动变速箱调教标定的控制程序与磨损后的硬件状态不匹配，可能需要调整或更换控制程序。

　　If the control program for automatic transmission tuning calibration does not match the worn hardware state, it may be necessary to adjust or replace the control program.

　　注意驾驶习惯：

　　Pay attention to driving habits:

　　避免频繁急加速和急刹车，减少对变速箱的冲击。

　　Avoid frequent rapid acceleration and braking to reduce the impact on the gearbox.

　　综上所述，自动变速箱顿挫的原因可能涉及多个方面，解决方法也需要根据具体情况而定。在解决顿挫问题时，建议车主及时到专业维修店进行检查和维修，以确保变速箱的正常工作和行车安全。

　　In summary, the reasons for automatic transmission jerking may involve multiple aspects, and the solution also needs to be determined according to specific situations. When solving the problem of jerking, it is recommended that car owners promptly go to a professional repair shop for inspection and maintenance to ensure the normal operation and driving safety of the gearbox.
