自动变速器，尤其是电子控制自动变速器，一般均认为结构复杂， ECU控制原理深奥，需要具有高水平的技术知识和专业技能，才能胜任其检修任务。但实际上，只要认真仔细地听取车主对故障的描述，并对此加以深入的分析，辅之以故障码的确认和故障症状方面的模拟再现，基本上便可 Automatic transmission, especially electronically controlled automatic transmission, are generally considered complex structure, the esoteric principle of ECU control, the need to have a high level of technical knowledge and expertise to be able to perform its maintenance tasks. In fact, however, as long as the owner carefully and carefully listens to the description of the fault by the owner and carries out an in-depth analysis of the fault, together with the verification of the fault code and the simulated reproduction of the fault symptom, basically
