How to Solve the Jerking Sensation in Automatic Transmission?
2 Answers
Automatic transmission jerking sensation can be resolved by: replacing the transmission fluid. Transmission fluid is an oil product that keeps the gear shift system clean, providing lubrication to extend the lifespan of the transmission components. It offers effective lubrication even under low-temperature conditions and reduces oil loss under harsh operating conditions. Depending on the structure of the transmission, transmission fluids are categorized into automatic transmission fluid (ATF) and manual transmission fluid. Automatic transmission typically refers to the car's automatic gear-shifting mechanism, where the transmission control system automatically selects the appropriate gear based on the engine's speed and load during driving, replacing the driver's subjective judgment of timing and gear-shifting operations.
I've experienced jerky gear shifts in automatic cars many times. It's usually caused by old or insufficient transmission fluid, leading to unstable oil pressure and rough shifting. When I bought a used car two years ago, there was always a clicking sound at startup. A friend later found the oil filter was clogged, and after replacing all the fluid, it became smooth. Also, driving habits have a big impact – like sudden acceleration can interfere with the transmission's computer control. My advice is to drive gently and check the fluid level every 30,000 km to avoid trouble. Modern cars have complex electronics, so sensor failures or software bugs can also cause jerking. It's important to update the ECU promptly to prevent minor issues from turning into major repairs.
