What Causes Jerking Sensation After a Car Goes Through Water?

[LaSpencer]

The strong jerking sensation during gear shifting after a car goes through water can be attributed to the following reasons: 1. Internal clutch pressure leakage in the transmission: Check for clutch damage and carry out repairs; 2. Transmission oil circuit blockage or poor flow: Wear in the oil circuit plate, long-term lack of transmission oil change leading to deterioration and reduced lubrication effectiveness, excessively dirty transmission filter affecting filtration, allowing wear particles to enter the valve body; 3. Transmission oil not at the standard level: Verify whether the transmission oil is at the standard level, as both insufficient or excessive transmission oil can cause this issue. For vehicles with a transmission oil dipstick, check if the oil level is at the standard mark when the engine is running; 4. Solenoid valve damage: Sludge in the transmission oil circulating and blocking the oil passages in the valve body can lead to jerking issues. Over time, this may result in a series of transmission problems such as overheating, impact, and slipping.
