What is the reason for frequently failing to shift from second gear to third gear?

[Kathy]

In the process of shifting from second gear to third gear, the reasons for frequent failure are as follows: Poor coordination between throttle and clutch: During the upshift process, you should first release the throttle, then press the clutch pedal, or both actions can be performed simultaneously. However, it's important to remember that you must not shift gears while pressing the throttle. If the throttle is not fully released during shifting, it may cause the gear shift to be jerky. Clutch not fully depressed: Before driving, you should familiarize yourself with the position and depth of the clutch pedal. If you shift gears without fully depressing the clutch, it can not only cause jerky shifting but also lead to gear grinding in the transmission. In severe cases, it can directly damage the gears inside the transmission.
