What Causes Jerking When Downshifting?
1 Answers
Here are the specific reasons for jerking when downshifting: 1. Engine oil passage blockage: The combustion of fuel is determined by the engine's ignition, intake, and fuel injectors, which are the power source of the engine. If the intake volume decreases, ignition weakens, or less fuel is injected, power will be insufficient, leading to a jerking sensation. 2. Dirty transmission fluid: This can cause damage to the solenoid valve. If sludge in the transmission fluid circulates and blocks the oil passages in the valve body, jerking issues will arise. Over time, this can lead to a series of transmission problems such as overheating, impact, and slippage. 3. Break-in period: Slight jerking during driving is normal as the vehicle's power output and component engagement are not at optimal levels. Additionally, the transmission's computer has a self-learning mechanism that continuously adjusts oil pressure for shifting.
