一、电磁阀引起的，电磁阀里面都有一个小阀芯是靠电流来工作的，跟阀体里的工作阀差不多，导致油压调节不稳定切换不均衡的现象。

1、 Caused by solenoid valves, there is a small valve core inside the solenoid valve that operates by current, similar to the working valve in the valve body, resulting in unstable oil pressure regulation and uneven switching.

二、是因为汽车电脑本身就会有学习驾驶的功能，并不是说在哪都能学习出来顿挫的表现，这个情况是比较少的，一般学习值即可。

2、 It is because the car computer itself has the function of learning to drive, which does not mean that stuttering performance can be learned everywhere. This situation is relatively rare, and generally clearing the learning value is sufficient.

三、阀体内部不通畅..阀体内部对工作环境的要求很高的，不能有脏东西进去，哪怕是粉末状的也会影响阀体内部换挡阀的工作通畅。

3、 The interior of the valve body is not unobstructed The requirements for the working environment inside the valve body are very high, and no dirt can enter, even if it is in powder form, it will affect the smooth operation of the shift valve inside the valve body.

四、变速箱活塞回位不好也会引起顿挫感，这个几率是比较小的也是偶发性的故障，小的换挡顿挫是可以接受的，严重的就是车的问题了。

4、 Poor return of the transmission piston can also cause jerking, which is a relatively small and occasional fault. Small shifting jerks are acceptable, but the most serious issue is with the car.

行驶中的故障表现，车在加油的时候，感觉无力，行驶中有抖动的现象发生。在3挡升4挡的时候，车子有顿挫的现象发生。行驶中还有4降3也顿挫的现象发生。

Malfunctions during driving, such as feeling weak while refueling and experiencing shaking while driving. When shifting from third gear to fourth gear, the car experiences jerking. There is also a phenomenon of 4 drops and 3 jerks during driving.

用电脑版读取的时候报了一堆故障码，报离合器E传动比监控，换挡机构3-4传动比监控，驻车锁止器被错误挂入，包括和车主一起试车的时候能明显感觉到顿。车主说他想一次性把车子修好，所以给客户的维修方案是全修全保，客户没有任何风险。客户很赞同，签好相关协议准备维修。

When reading with the computer version, a bunch of fault codes were reported, including clutch E gear ratio monitoring, gear shift mechanism 3-4 gear ratio monitoring, incorrect engagement of the parking lock, and noticeable stuttering during the test drive with the owner. The car owner said he wants to fix the car all at once, so the repair plan given to the customer is full repair and full warranty, and the customer has no risk. The customer agrees and signs the relevant agreement to prepare for repair.

补充一下（变速箱再制造维修需要基本的工序；抬箱、拆散、清洗、零件检测、故障再分析、变扭器送入再生区、阀体送入阀体拆解区、总成安装、技术检测、总装、总装测试、出库登记。）

Just to add (basic processes are required for remanufacturing and repairing the gearbox; lifting, dismantling, cleaning, parts inspection, fault reanalysis, torque converter sent to the regeneration area, valve body sent to the valve body disassembly area, assembly installation, technical inspection, final assembly, final assembly testing, and outbound registration)

液力变矩器是安装在发动机的飞轮盘上，利用工作油液将发动机的转矩传递给自动变速箱中的齿轮变速机构，主要传递增加扭矩。变速箱摩擦片如果烧了，变矩器必须分解维修清洗才能用！

A hydraulic torque converter is installed on the flywheel plate of the engine, which uses working fluid to transfer the engine's torque to the gear transmission mechanism in the automatic transmission, mainly transmitting increased torque. If the transmission friction plate is burned, the torque converter must be disassembled, repaired, and cleaned before use!
