What Causes the Jerking Sensation When Shifting Gears in a Manual Transmission Car?

[Annabeth]

Manual transmission cars experience jerking sensations during gear shifts due to: 1. Mismatch between the engine speed and wheel speed; 2. Faulty components within the engine such as spark plugs or ignition coils, which can lead to weak acceleration and severe shaking or jerking while driving; 3. Blockage or malfunction of the fuel pump, causing low oil pressure and preventing proper fuel atomization and combustion. A manual transmission, generally referred to as a manual gearbox, functions to alter the gear ratio, also known as the gear ratio. It utilizes the principle of leverage to amplify engine torque through the largest diameter gear in the low-speed range, assisting the vehicle in initiating forward movement.
