What Causes Jerking When Accelerating in Second and Third Gears with a Manual Transmission?
2 Answers
The reason for jerking when accelerating in second and third gears with a manual transmission is due to issues such as transmission blockage. Below are the specific causes of jerking when accelerating in second and third gears with a manual transmission: 1. Damaged Solenoid Valve: A damaged solenoid valve is a significant cause of jerking. A simple way to distinguish this is that if it occurs occasionally without a discernible pattern, it is irregular. If it happens consistently when reaching a certain speed or shifting to a specific gear (e.g., from 2nd to 3rd gear), it indicates a fixed jerking issue. 2. Transmission Blockage: If there is sludge blocking the oil passages in the transmission's internal circulation, it can lead to stumbling issues. This can cause a series of transmission problems such as overheating, impact, and slipping, resulting in jerking during gear shifts.
It's quite common to experience jerking when accelerating in second or third gear with my manual transmission car, mainly due to improper clutch coordination—like releasing the clutch too quickly without matching the throttle or shifting at too low RPMs. Worn clutch discs can also be a reason, as thinning makes engagement less smooth. It's important to develop the habit of slowly lifting the clutch and waiting for the RPMs to stabilize before acting. For older cars, dirty transmission oil can increase resistance, so remember to change the oil regularly and check the clutch travel. Avoid sudden acceleration in daily driving and keep the lubrication system clean to reduce such issues. New drivers will get the hang of it with a bit more practice.
