Why Does an Automatic Transmission Car Experience Jerking When Shifting Gears?

[Martin]

Automatic transmission cars experiencing jerking when shifting gears is often due to insufficient transmission fluid or the need for a fluid change. The transmission fluid in automatic cars must be replaced regularly because gear shifting relies entirely on this fluid. Only through regular replacement can the normal operation of internal transmission components be ensured, preventing jerking sensations. Transmission fluid is a lubricant that keeps the gear system clean, ensuring the transmission works properly and extending the lifespan of the drivetrain. Automatic transmission gear positions are generally indicated by the letters P, R, N, D, S, and L, representing Park, Reverse, Neutral, Drive, Sport mode, and Low gear mode, respectively.
