自動變速箱頓挫的原因及解決方法主要包括以下幾點：

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

　　原因

　　reason

　　油溫過高：油溫過高會影響變速箱的正常工作，導致頓挫。

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

　　臟污與雜質(zhì)堵塞閥體：閥體內(nèi)部出現(xiàn)頑固的污垢和雜質(zhì)堵塞，會導致無法調(diào)節(jié)油壓，進而形成頓挫、沖擊等問題。

　　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.

　　電磁閥損壞：電磁閥出問題，會影響變速箱的換擋邏輯和順暢度。

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

　　變速箱內(nèi)部離合器泄壓：離合器壓力不足，無法正常傳遞動力，就容易產(chǎn)生頓挫。

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

　　變速箱油路發(fā)卡不順暢：油路發(fā)卡不順暢或磨損，油液流動受阻，會造成頓挫。

　　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.

　　變速箱油未添加到標準值：油液量不合適，無法為變速箱提供良好的潤滑和工作條件。

　　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.

　　自動變速箱調(diào)教標定的控制程序與磨損后的硬件狀態(tài)不匹配：原本的控制程序是按照全新的自動變速箱編寫的，硬件磨損后就可能出現(xiàn)頓挫。

　　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.

　　檢查并更換變速箱油：

　　Check and replace the transmission oil:

　　定期檢查和更換變速箱油，確保油液的清潔和正常量。建議每行駛2年或4萬公里后更換一次。

　　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.

　　如果發(fā)現(xiàn)變速箱油中有鐵屑等物質(zhì)，可能說明自動變速器中制動器和離合器的摩擦片磨損，需及時更換變速箱油。

　　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.

　　檢查變速箱油尺，確保變速箱油添加到標準刻度。如果變速箱油少了或者多了都會導致頓挫故障出現(xiàn)。

　　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.

　　清洗閥體：

　　Cleaning the valve body:

　　如果發(fā)現(xiàn)閥體內(nèi)部出現(xiàn)了污垢和雜質(zhì)，請及時聯(lián)系專業(yè)的汽車維修人員進行清洗。

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

　　檢查并維修電磁閥：

　　Check and repair the solenoid valve:

　　電磁閥損壞時，應(yīng)及時到4S店或者汽車維修店進行檢查和維修。

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

　　檢查并修理變速箱內(nèi)部離合器：

　　Check and repair the internal clutch of the gearbox:

　　如果變速箱內(nèi)部離合器泄壓，應(yīng)檢查離合器是否損壞，并進行修理。

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

　　檢查并更換油泵：

　　Check and replace the oil pump:

　　油泵故障是導致自動變速箱頓挫的一個常見原因，發(fā)現(xiàn)油泵有問題時，應(yīng)及時檢查和維修。

　　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.

　　調(diào)整或更換控制程序：

　　Adjust or replace the control program:

　　如果自動變速箱調(diào)教標定的控制程序與磨損后的硬件狀態(tài)不匹配，可能需要調(diào)整或更換控制程序。

　　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.

　　注意駕駛習慣：

　　Pay attention to driving habits:

　　避免頻繁急加速和急剎車，減少對變速箱的沖擊。

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

　　綜上所述，自動變速箱頓挫的原因可能涉及多個方面，解決方法也需要根據(jù)具體情況而定。在解決頓挫問題時，建議車主及時到專業(yè)維修店進行檢查和維修，以確保變速箱的正常工作和行車安全。

　　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.
