What Are the Causes of Gear Shifting Jerkiness in Cars?
2 Answers
The causes of gear shifting jerkiness in cars are: 1. Internal clutch pressure leakage in the transmission; 2. Blocked or unsmooth transmission oil passages, worn oil passage plates, long-term lack of transmission fluid changes, dirty transmission filter screens leading to poor filtration that allows wear particles to enter the valve body; 3. Transmission oil leakage; 4. Damaged solenoid valves. Solutions for gear shifting jerkiness in cars: 1. Adjust the shifting RPM by pressing the accelerator to raise the RPM to 2000 before shifting; 2. Adjust the gear engagement sequence, such as shifting directly from 3rd gear to 5th gear; 3. Shorten the shifting time; 4. Lightly press the accelerator during shifting; 5. Turn off the vehicle and restart it.
Having driven for decades, I've seen too many gear-shifting jerks. The most common issue is the clutch: severely worn clutch plates, improperly adjusted pedals, or incomplete disengagement can cause power interruption during shifting, making the car lurch forward. Or it could be due to deteriorated or insufficient transmission fluid, leading to poor lubrication and rough gear rotation, resulting in jerks. Engine RPM not matching the gear, like suddenly accelerating at low speeds, can also cause shaking. I remember once on a bumpy rural road when some transmission fluid leaked, the car jerked badly—adding fluid immediately smoothed it out. Small issues left unfixed can lead to costly clutch replacements. Regularly checking pedal adjustments and fluid levels saves a lot of hassle—driving safety comes first.
