What Causes Jerking During Hard Acceleration in a Manual Transmission?

[AryaRose]

Here are the specific reasons for jerking during acceleration in a manual transmission: Engine oil passage blockage: The combustion of fuel, which is the power source of the engine, is determined by the engine's ignition, air intake, and fuel injectors. If the air intake decreases, ignition weakens, or less fuel is injected, the power output will be insufficient, leading to a jerking sensation. Dirty transmission fluid: This can cause damage to the solenoid valve. If sludge accumulates in the transmission fluid and circulates within the transmission, blocking the oil passages in the valve body, it can result in jerking issues. Over time, this can lead to a series of transmission problems such as overheating, impact, and slippage. Break-in period: Mild jerking during driving is normal during the break-in period because the vehicle's power output and component engagement are not at their optimal levels. Additionally, the transmission's computer has a self-learning mechanism that continuously adjusts oil pressure for gear shifting.
