自动挡变速箱出现故障前通常有以下征兆：

　　Before an automatic transmission malfunctions, there are usually the following symptoms:

　　换挡时间异常 ：

　　Abnormal shifting time:

　　如果换挡时间明显比往常延长或变短，可能表明变速箱的传动比不成比例。

　　If the shifting time is significantly longer or shorter than usual, it may indicate that the transmission ratio of the gearbox is not proportional.

　　变速箱渗油 ：

　　Transmission oil leakage:

　　变速箱开始渗油可能意味着密封件老化或损坏。

　　The beginning of oil leakage in the gearbox may indicate aging or damage to the seals.

　　变速箱打滑，加速无力 ：

　　Transmission slipping, weak acceleration:

　　当车辆在加速时，如果发动机转速升高但车速没有提升，可能是变速箱打滑。

　　When the vehicle is accelerating, if the engine speed increases but the vehicle speed does not increase, it may be due to the gearbox slipping.

　　变速箱内产生异味 ：

　　Odor generated in the gearbox:

　　箱内油因温度过高可能燃烧产生异味，这可能是箱内某些部件异常工作所致。

　　The oil inside the box may burn and produce an odor due to high temperature, which may be caused by abnormal operation of certain components inside the box.

　　变速箱异响 ：

　　Abnormal noise from gearbox:

　　在车辆怠速或行驶过程中，听到变速器有异响，可能是由于内部零件磨损或润滑不良。

　　During vehicle idling or driving, if you hear abnormal noises from the transmission, it may be due to wear or poor lubrication of internal components.

　　变速箱温度过高 ：

　　Transmission temperature too high:

　　仪表盘显示变速箱温度过高，可能是内部高负荷运转或冷却系统故障。

　　The dashboard displays that the transmission temperature is too high, which may be due to internal high load operation or cooling system failure.

　　变速箱顿挫 ：

　　Transmission jerking:

　　在行驶过程中，变速箱在升挡时产生冲击、振动或顿挫感，可能是内部零件磨损或液压控制系统问题。

　　During driving, the gearbox may experience shock, vibration, or jerking when upshifting, which may be due to internal component wear or hydraulic control system issues.

　　油液泄漏 ：

　　Oil leakage:

　　变速箱油液泄漏会导致油量不足，并可能污染其他部件。

　　Transmission fluid leakage can lead to insufficient oil volume and may contaminate other components.

　　换挡延迟或不顺畅 ：

　　Delayed or unsmooth gear shifting:

　　如果在换挡时感觉到延迟或不顺畅，可能是变速箱控制模块或传感器出现故障。

　　If you feel a delay or discomfort during gear shifting, it may be due to a malfunction in the transmission control module or sensor.

　　仪表盘警告灯亮起 ：

　　The dashboard warning light is on:

　　变速箱相关的警告灯亮起可能是变速箱出现故障的直接指示。

　　The warning lights related to the gearbox may light up as a direct indication of a gearbox malfunction.

　　如果您的车辆出现上述任何症状，建议您尽快到专业的汽车维修店进行检查和维修，以避免造成更严重的损害。

　　If your vehicle shows any of the above symptoms, it is recommended that you go to a professional car repair shop for inspection and repair as soon as possible to avoid causing more serious damage.
