低速行驶抖动顿挫几乎成为双离合变速箱的代名词，不论是自主、合资还是进口品牌，均难逃此厄运。除此以外，部分品牌车型的手动、AT及CVT变速箱也出现同类问题，尤其是以节油、平顺著称的CVT变速箱也出现了大量相关投诉，令人较为意外。

The shaking and jerking during low-speed driving have almost become synonymous with dual clutch transmissions, and both domestic, joint venture, and imported brands cannot escape this fate. In addition, some brand models also have similar problems with manual, AT, and CVT transmissions, especially the CVT transmission, which is known for its fuel efficiency and smoothness, has received a large number of related complaints, which is quite surprising.

一、双离合变速箱稳定性成话题

1、 Stability of dual clutch transmission becomes a topic of discussion

双离合变速箱有其自身技术优势，但稳定性和可靠性存在一定短板，据车质网投诉数据显示，在抖动顿挫问题中双离合变速箱投诉量最大，且涉及品牌车型最多。虽然从理论上讲，双离合器变速箱会在换挡响应速度、油耗经济性等方面具备一定优势，但干式双离合并不带有单独的冷却系统，仅靠风冷及变速箱油的热导进行散热，在市区堵车情况下，离合器长期半联动磨损且容易导致温度升高。此时，双离合机构、机电控制单元及电器元部件难以承受长期的高温考验，可能造成系统寿命的缩减、加速变速箱损坏。据悉，大众已意识到干式双离合产品中存在的问题，并生产出7速湿式双离合变速箱予以替代，对此自主及美系品牌也应加快解决产品稳定性差的步伐。

The dual clutch transmission has its own technological advantages, but there are certain shortcomings in stability and reliability. According to complaint data from the Car Quality Network, the dual clutch transmission has the highest number of complaints and involves the most brand models in terms of shaking and jerking issues. Although theoretically, dual clutch transmissions have certain advantages in shifting response speed, fuel economy, and other aspects, dry dual clutch transmissions do not have a separate cooling system and rely solely on air cooling and thermal conductivity of the transmission oil for heat dissipation. In urban traffic jams, long-term semi coupled wear of the clutch can easily lead to temperature rise. At this point, the dual clutch mechanism, electromechanical control unit, and electrical components are unable to withstand long-term high temperature tests, which may result in reduced system lifespan and damage to the acceleration gearbox. It is reported that Volkswagen has realized the problems in dry dual clutch products and has produced a 7-speed wet dual clutch transmission to replace them. Both domestic and American brands should accelerate their efforts to solve the problem of poor product stability.

二、手动变速箱也不排除故障可能

2、 Manual transmission also cannot rule out the possibility of malfunction

手动变速箱在使用过程中出现抖动顿挫现象，很多车主第一反应都是驾驶习惯问题，但在部分品牌车型出现投诉相对集中的情况，却难以用个案来解释。从故障现象来看，手动变速箱出现抖动顿挫一般是在换挡间隙，尤其是在二、三挡间切换时车辆顿挫感较为严重，但4S店给出的“正常现象”答复，却很难服众。实际上，手动变速箱出现抖动顿挫问题，也与离合器及变速箱输入轴、同步器等相关部件的配合有一定关系。如果出现旷量或安装位置发生偏移，将会出现上述问题。除此以外，发动机行车电脑ECU也是出现顿挫感的罪魁祸首，个别厂家已对此进行改进，更换新ECU后顿挫问题已得到解决。综上所述，当手动变速箱出现换挡抖动顿挫问题后车主不要掉以轻心，及时到4S店排查故障原因。

During the use of manual transmissions, there may be shaking and jerking phenomena. Many car owners' first reaction is due to driving habits, but in some brand models, complaints are relatively concentrated, which is difficult to explain with individual cases. From the perspective of the fault symptoms, the shaking and jerking of a manual transmission are usually during gear shifting, especially when the vehicle experiences severe jerking when switching between second and third gears. However, the "normal phenomenon" response given by the 4S store is difficult to convince the public. In fact, the shaking and jerking problems of manual transmissions are also related to the coordination of clutch, transmission input shaft, synchronizer and other related components. If there is clearance or installation position deviation, the above problems will occur. In addition, the engine's onboard computer ECU is also the main culprit for the jerking sensation, and some manufacturers have made improvements to address this issue. After replacing the ECU with a new one, the jerking problem has been resolved. In summary, when the manual transmission experiences gear shifting shaking and jerking, car owners should not take it lightly and promptly go to the 4S store to investigate the cause of the malfunction.

三、CVT变速箱也受顿挫困扰

3、 CVT gearbox also suffers from jerking

一提到CVT变速箱，不少人的印象可能就是其出色的节油性和平顺性，但从接到的投诉来看，变速箱抖动顿挫问题投诉中也不乏CVT的身影。其中，日产品牌所使用的CVT变速箱可谓命运多舛，冬季升挡慢的问题还未绝迹，如今抖动顿挫问题的出现又波及多款车型，而且从故障现象看其中有共通之处。其主要表现为：30-50km/h升挡时有明显拖曳感和顿挫感；在停车减速到15-18km/h时速时，会出现两次较为明显的顿挫感，随后出现窜车。据了解，日产所使用的这款CVT变速箱带有一套行星齿轮组，而出现顿挫感是否与其结构有关，目前厂家及4S店并未给出明确说明。

When it comes to CVT transmissions, many people's impression may be of their excellent fuel efficiency and smoothness, but from the complaints received, it can be seen that CVT is also present in the complaints about transmission shaking and jerking. Among them, the CVT gearbox used by Nissan brand has had a difficult fate. The problem of slow upshifting in winter has not disappeared, and now the occurrence of shaking and jerking problems has affected multiple models, and there are commonalities in the fault symptoms. Its main manifestations are: obvious dragging and jerking when upshifting at 30-50km/h; When slowing down to a speed of 15-18km/h during parking, there will be two noticeable jolts followed by a sudden movement. It is understood that the CVT gearbox used by Nissan is equipped with a set of planetary gear sets, and whether the jerking sensation is related to its structure has not been clearly explained by the manufacturer or 4S dealership at present.
