What are the reasons for not smoothly shifting gears?

The specific reasons for not smoothly shifting gears: 1. Premature commands: Shifting gears before the voice prompt. 2. Too fast shifting: Generally, when passing through neutral gear, a slight pause (about 0.5~1 second) is needed to allow the computer to sense the gear passing through neutral. If the operation is too fast, neutral gear usually cannot be sensed. Below are specific introductions to gear selection in different road conditions: 1. Uphill: This type of road requires high torque intervention, so you can use "D-" to downshift. However, sometimes when the power is sufficient, you also need to use "D+" to upshift to prevent power waste and damage to the engine and transmission. When encountering steep slopes, even after downshifting, the vehicle may still lack power. In this case, use the S gear (sport mode). 2. Downhill: Use "D+" to shift up to D2 or D3 gear, which can restrain the engine to achieve a braking effect. Generally, 2-3 gears are sufficient for moderate slopes, but when encountering steep slopes, pay attention to switching to 1st gear. If the vehicle starts to slide faster, use "D-" to downshift and control the vehicle.
As a veteran driver with over 20 years of manual transmission experience, I've encountered many gear-shifting issues. The most common problems are releasing the clutch too quickly or improper throttle coordination. Smooth shifting requires limb coordination – for example, fully depressing the clutch before engaging gear, then lifting the clutch as gently as stepping on cotton while simultaneously matching with throttle input. Another critical mistake is speed-gear mismatch: using high gear at low speed causes stalling, while low gear at high speed results in jerking forward. Regular clutch plate inspection is crucial – I once discovered a worn pressure plate causing semi-clutch slippage, making shifts particularly rough. Developing good habits like starting in first gear and shifting decisively, plus building driver-car默契 through磨合, makes all the difference.
