2、描述故障具体现象和可能的故障原因，进 行详细的故障机理分析，并将自动变速器动态性能试验运用其中，有失速试验和时滞 试验，对故障进行检测诊断，准确确定故障部位。进而对故障进行排除，并画出故障 诊断流程图。 最后通过现场收集实际案例进行分析， 证明故障检测诊断分析的正确性。 关键词关键词：自动变速器；结构组成；常见故障；检测与维修 Abstract With the scientific and technological progress, cars have become the mainstream of the world, the invention of cars brings man
