What Causes Gear Shifting Jerk in Cars?
1 Answers
Automatic transmission shifting jerkiness may be caused by: transmission clutch pressure leakage; transmission oil circuit blockage or poor flow; transmission fluid not filled to standard; or solenoid valve damage. The engine's power is transmitted through the transmission, which is also a key factor affecting fuel consumption. Generally, automatic transmissions consume 10% more fuel than manual transmissions. Whether manual or automatic, more gears mean better fuel efficiency. Below is relevant information: 1. Solenoid valve damage: If sludge in the transmission fluid circulates and blocks the oil passages in the valve body, it can cause shifting jerkiness. Over time, this can lead to transmission overheating, impact, slippage, and other transmission issues. 2. Transmission fluid not filled to standard: Check whether the transmission fluid is filled to the correct level. Both insufficient and excessive transmission fluid can cause this issue. Vehicles with a transmission dipstick can check the fluid level against the standard markings when the engine is running.
