What Causes Jerking Sensation in Automatic Transmission Vehicles While Driving?

[StNatalie]

Here are the specific reasons for jerking sensation in automatic transmission vehicles while driving: 1. Clogged engine oil passages: 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 fuel injection reduces, the power output will be insufficient, leading to a jerking sensation. 2. Dirty transmission fluid: This can cause damage to the solenoid valves. If sludge in the transmission fluid circulates and blocks the oil passages in the valve body, it will result in jerking issues. Over time, this can lead to a series of transmission problems such as overheating, impact, and slippage. 3. Break-in period: A slight jerking sensation during driving is normal as 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.
