How to Shift Gears Without Jerking?
2 Answers
Usually when driving, releasing the accelerator too quickly can cause a lack of power during acceleration, leading to jerking. If the clutch is partially engaged, the vehicle's power transmission may be affected, so fully depressing the clutch pedal will help avoid jerking. The gear selection in a manual transmission is crucial. After depressing the clutch, the vehicle may gradually slow down due to wind resistance and friction, but it can also gradually accelerate. When the vehicle speed is calculated correctly and the engine reaches the required RPM for the target gear, it's possible to maintain the current RPM, preferably slightly higher. Then, slowly release the clutch while increasing the throttle until the clutch is fully released. During this process, it's essential to keep the engine RPM at 3500.
Having driven manual transmission cars for decades, the jerky sensation always makes passengers uncomfortable, with clutch control being the key. I'm accustomed to slowly releasing the clutch with my left foot when shifting gears—never letting it out all at once—while gently pressing the accelerator with my right foot to match the RPM. For upshifting, it's smoother to shift on level roads; for example, shifting uphill when RPM is insufficient easily causes shuddering. Downshifting requires rev-matching: lightly tap the throttle to raise the RPM before releasing the clutch. During my beginner days, I practiced starting repeatedly in parking lots, from first to second gear, feeling for the clutch engagement point—each car's position varies, but familiarity makes it effortless. Weather also plays a role; cold starts tend to be jerkier, but it improves once the car warms up. Over time, a natural rhythm develops, making driving as smooth as flowing water.
