一、電磁閥引起的，電磁閥里面都有一個小閥芯是靠電流來工作的，跟閥體里的工作閥差不多，導致油壓調節不穩定切換不均衡的現象。

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、是因為汽車電腦本身就會有學習駕駛的功能，并不是說在哪都能學習出來頓挫的表現，這個情況是比較少的，一般清除學習值即可。

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、閥體內部不通暢..閥體內部對工作環境的要求很高的，不能有臟東西進去，哪怕是粉末狀的也會影響閥體內部換擋閥的工作通暢。

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、變速箱活塞回位不好也會引起頓挫感，這個幾率是比較小的也是偶發性的故障，小的換擋頓挫是可以接受的，嚴重的就是車的問題了。

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.

行駛中的故障表現，車在加油的時候，感覺無力，行駛中有抖動的現象發生。在3擋升4擋的時候，車子有頓挫的現象發生。行駛中還有4降3也頓挫的現象發生。

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.

用電腦版讀取的時候報了一堆故障碼，報離合器E傳動比監控，換擋機構3-4傳動比監控，駐車鎖止器被錯誤掛入，包括和車主一起試車的時候能明顯感覺到頓。車主說他想一次性把車子修好，所以給客戶的維修方案是全修全保，客戶沒有任何風險。客戶很贊同，簽好相關協議準備維修。

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.

補充一下（變速箱再制造維修需要基本的工序；抬箱、拆散、清洗、零件檢測、故障再分析、變扭器送入再生區、閥體送入閥體拆解區、總成安裝、技術檢測、總裝、總裝測試、出庫登記。）

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)

液力變矩器是安裝在發動機的飛輪盤上，利用工作油液將發動機的轉矩傳遞給自動變速箱中的齒輪變速機構，主要傳遞增加扭矩。變速箱摩擦片如果燒了，變矩器必須分解維修清洗才能用！

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!
