在选择自动变速箱维修厂家时，建议您重点关注以下几个方面：

When choosing an automatic transmission repair manufacturer, it is recommended that you focus on the following aspects:

首先，应选择信誉良好的修理机构，可以通过朋友推荐、网络评价或行业口碑等渠道了解其服务质量和信誉度。

Firstly, it is advisable to choose a reputable repair institution, which can be recommended by friends, evaluated online, or based on industry reputation to understand its service quality and credibility.

其次，务必确认修理机构具备合法的营业执照及相关的维修资质认证，这是保障维修质量的基本前提。

Secondly, it is necessary to confirm that the repair institution has a legal business license and relevant maintenance qualification certification, which is the basic prerequisite for ensuring the quality of maintenance.

第三，要详细了解修理机构的维修保修政策，明确保修期限和范围，以免后续出现问题无法得到妥善解决。

Thirdly, it is necessary to have a detailed understanding of the repair and warranty policies of the repair institution, clarify the warranty period and scope, in order to avoid problems that cannot be properly resolved in the future.

第四，需要确认修理机构使用的备件质量，优先选择原厂备件或经过权威认证的优质替代件。

Fourthly, it is necessary to confirm the quality of spare parts used by the repair institution, and prioritize the selection of original factory spare parts or high-quality substitute parts that have been certified by authorities.

最后，在维修前应与修理机构充分沟通，明确故障现象、维修方案及预期费用，避免因信息不对称而产生纠纷。

Finally, before maintenance, it is necessary to communicate fully with the repair institution, clarify the fault symptoms, maintenance plan, and expected costs, and avoid disputes caused by information asymmetry.

自动变速箱的维修通常遵循以下标准流程：

The maintenance of automatic transmissions usually follows the following standard procedures:

第一步是故障诊断，专业技师会使用专用诊断设备读取车辆故障码，结合路试情况准确定位故障点。

The first step is fault diagnosis. Professional technicians will use specialized diagnostic equipment to read vehicle fault codes and accurately locate the fault point based on road test results.

第二步是拆卸和清洁，对于内部存在严重油泥或沉积物的变速箱，需进行彻底拆解和清洗，此过程需严格按照操作规程进行，避免损伤精密部件。

The second step is disassembly and cleaning. For gearboxes with severe oil sludge or sediment inside, thorough disassembly and cleaning are required. This process must be strictly carried out in accordance with operating procedures to avoid damaging precision components.

第三步是更换损坏零件，根据检测结果更换离合器片、齿轮组、轴承等磨损件，所有替换件均需符合原厂规格要求。

The third step is to replace damaged parts. Based on the test results, replace worn parts such as clutch plates, gear sets, bearings, etc. All replacement parts must meet the original factory specifications.

第四步是系统调整和校准，维修完成后需对变速箱控制系统进行重新匹配，包括传感器校准、离合器间隙调整等关键步骤。

The fourth step is system adjustment and calibration. After the maintenance is completed, the transmission control system needs to be re matched, including key steps such as sensor calibration and clutch clearance adjustment.

最后是测试和保养环节，通过路试验证维修效果，确保换挡平顺无异常，同时更换变速箱油和滤清器以保持最佳工作状态。

Finally, there is the testing and maintenance phase, which verifies the repair effect through road tests, ensures smooth and normal gear shifting, and replaces the transmission oil and filter to maintain optimal working condition.

需要特别提醒的是，自动变速箱结构复杂、精密度高，非专业人员擅自拆修极易造成二次损坏。若您不具备专业维修知识和经验，建议委托具有丰富变速箱维修经验的技师进行处理，他们能够凭借专业设备和多年经验，确保故障得到准确诊断和彻底修复。定期专业保养和正确使用习惯，是延长自动变速箱使用寿命的关键。

It should be noted that automatic transmissions have complex structures and high precision, and unauthorized disassembly and repair by non professionals can easily cause secondary damage. If you do not have professional maintenance knowledge and experience, it is recommended to entrust technicians with rich experience in gearbox maintenance to handle it. They can rely on professional equipment and years of experience to ensure accurate diagnosis and thorough repair of faults. Regular professional maintenance and correct usage habits are key to extending the service life of automatic transmissions.
