　　Jinan automatic transmission maintenance science popularization: analysis of the gap between domestic manual/AT/dual clutch/DHT transmissions, and full knowledge of maintenance points

　　在济南，开国产车的车主越来越多，国产变速箱的表现也备受关注。虽然国产变速箱在不断进步，但与国际一流水平仍有差距，这也给维修带来了不同的挑战。今天就结合济南本地的维修经验，给大家讲讲国产不同类型变速箱的维修要点，希望能帮到大家。

　　In Jinan, there are more and more owners of domestically produced cars, and the performance of domestic transmissions is also receiving attention. Although domestic transmissions are constantly improving, there is still a gap with the international first-class level, which brings different challenges to maintenance. Today, based on the local maintenance experience in Jinan, I will talk about the maintenance points of different types of domestic transmissions, hoping to help everyone.

　　先说说手动变速箱。国产手动变速箱的可靠性和寿命已经接近国际一流水平，基本能做到 “扛造”，但在换挡手感上还有差距，比如档位自动吸入的感觉不够明显。在济南维修国产手动变速箱，常见的问题主要集中在换挡机构磨损、离合器片打滑等。维修时，重点检查换挡拨叉、同步器等部件，更换磨损的离合器片和压盘，同时对换挡机构进行调校，能有效改善换挡手感。对于 3、5 万块钱的经济型手动挡车，由于成本限制，配件质量可能稍差，维修时更要注意选择合格的配件。

　　Let's talk about the manual gearbox first. The reliability and service life of domestically produced manual transmissions have approached the international first-class level, and can basically achieve "durability". However, there is still a gap in the shifting feel, such as the less obvious feeling of automatic gear suction. The common problems in repairing domestic manual transmissions in Jinan mainly focus on wear and tear of the shifting mechanism and slipping of the clutch plates. During maintenance, it is important to inspect components such as shift forks and synchronizers, replace worn clutch plates and pressure plates, and adjust the shifting mechanism to effectively improve the shifting feel. For economy manual transmission vehicles priced at 30000 to 50000 yuan, due to cost constraints, the quality of accessories may be slightly inferior, so it is important to choose qualified accessories during maintenance.

　　再看 AT 自动变速箱。目前国产的 AT 变速箱，如奇瑞的 8AT 和长城的 9AT，虽然已经装车使用，但市场验证时间较短，整体表现还不够稳定，顿挫感相对明显。AT 变速箱是制造难度最大、调校最复杂的变速箱类型，国产 AT 在这方面的差距还比较大，可能需要 5 到 10 年的时间才能赶上国际一流水平。在济南维修国产 AT 变速箱，建议选择有经验的维修厂，因为其内部结构复杂，对维修技术要求较高。如果出现严重故障，可能需要更换原厂的阀体或变速箱总成，维修成本相对较高。现阶段，济南的车主如果更看重可靠性和驾驶感受，选择搭载采埃孚、爱信等国际品牌 AT 变速箱的车型会更稳妥。

　　Let's take a look at the AT automatic transmission again. At present, domestically produced AT transmissions, such as Chery's 8AT and Great Wall's 9AT, have been installed and used, but the market validation time is relatively short, and the overall performance is not stable enough, with a relatively obvious jerky feeling. The AT gearbox is the most difficult type of gearbox to manufacture and adjust, and there is still a significant gap between domestic ATs in this regard. It may take 5 to 10 years to catch up with the international first-class level. When repairing domestic AT transmissions in Jinan, it is recommended to choose an experienced repair shop because of its complex internal structure and high requirements for repair technology. If there is a serious malfunction, it may be necessary to replace the original valve body or gearbox assembly, and the repair cost is relatively high. At present, if car owners in Jinan value reliability and driving experience more, choosing models equipped with international brands such as ZF and Aisin AT transmissions will be more reliable.

　　双离合变速箱是国产变速箱的主力类型。干式双离合的制造难度相对较低，国产干式双离合的质量尚可，故障率略高于大众、奔驰等品牌，但还在可接受范围内，日常使用没有问题。在济南的拥堵路况下，干式双离合容易出现离合器过热、抖动等问题，维修时主要更换离合器片和分离轴承。湿式双离合的散热更好，稳定性明显优于干式双离合，但国产湿式双离合的表现还不够过硬，过去的产品问题较多。维修国产湿式双离合，要重点检查液压系统和电子控制系统，这两个系统的故障率相对较高。近两年，国产干式双离合的质量也在不断提升，电子和液压系统的故障有所减少，但仍高于湿式双离合，济南的车主在选择时可以根据自己的用车环境来考虑。

　　Dual clutch transmission is the main type of domestic transmission. The manufacturing difficulty of dry dual clutch is relatively low, and the quality of domestically produced dry dual clutch is acceptable, with a slightly higher failure rate than brands such as Volkswagen and Mercedes Benz, but still within an acceptable range, and there are no problems with daily use. In the congested road conditions of Jinan, dry dual clutch transmission is prone to problems such as clutch overheating and shaking. During maintenance, the main focus is on replacing clutch plates and release bearings. Wet dual clutch has better heat dissipation and significantly better stability than dry dual clutch, but the performance of domestic wet dual clutch is not strong enough, and there have been many problems with previous products. When repairing domestic wet dual clutch, it is important to focus on inspecting the hydraulic system and electronic control system, as these two systems have a relatively high failure rate. In the past two years, the quality of domestically produced dry dual clutch transmissions has been continuously improving, with a reduction in electronic and hydraulic system failures, but still higher than wet dual clutch transmissions. Car owners in Jinan can consider their own driving environment when choosing.

　　最后是混动专用的 DHT 变速箱。在这一领域，国产变速箱暂时处于领先地位，质量也相对稳定。DHT 变速箱分为 2 档、3 档和 4 档等不同类型，结构相对简单，主要与混动系统配合工作。在济南维修国产 DHT 变速箱，由于其技术较新，建议选择品牌授权的 4S 店或专业的混动维修厂，以保证维修质量。不过，混动系统的发展时间还不长，未来的稳定性还有待进一步观察。

　　Finally, there is a DHT gearbox specifically designed for hybrid use. In this field, domestic transmissions are currently in a leading position, and their quality is relatively stable. The DHT gearbox is divided into different types such as 2nd gear, 3rd gear, and 4th gear, with a relatively simple structure and mainly works in conjunction with the hybrid system. When repairing a domestically produced DHT gearbox in Jinan, due to its relatively new technology, it is recommended to choose a brand authorized 4S store or a professional hybrid repair shop to ensure the quality of the repair. However, the development time of hybrid systems is not long, and the future stability still needs further observation.

　　总之，济南的车主在维修国产变速箱时，要根据变速箱的类型选择合适的维修方式和维修厂。对于手动变速箱和干式双离合，维修相对简单；对于 AT 变速箱和湿式双离合，对维修技术要求较高；对于 DHT 变速箱，要选择专业的混动维修机构。希望这些信息能帮到大家，让大家在维修国产变速箱时少走弯路。

　　In short, car owners in Jinan should choose the appropriate repair method and repair shop according to the type of gearbox when repairing domestic transmissions. For manual transmissions and dry dual clutch transmissions, maintenance is relatively simple; For AT transmission and wet dual clutch, high maintenance technology requirements are required; For DHT gearbox, it is necessary to choose a professional hybrid maintenance organization. I hope this information can help everyone avoid detours when repairing domestic transmissions.
