What Causes the Jerking Sensation When Shifting Gears in an Automatic Transmission Car?
1 Answers
Automatic transmission cars may experience a jerking sensation when shifting gears due to the following reasons: 1. Internal clutch pressure leakage in the transmission; 2. Blocked or obstructed transmission oil passages, wear and tear on the oil passage plate, or degraded transmission oil leading to reduced lubrication effectiveness; 3. Insufficient transmission oil level below the standard mark; 4. Damaged solenoid valve, causing sludge in the transmission oil to circulate and clog the oil passages within the valve body. An automatic transmission eliminates the need for manual gear shifting by the driver, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Typically, automatic transmission cars feature six gear positions arranged from top to bottom as follows: P, R, N, D, S, L.
