Does an Automatic Transmission Need Oil?
2 Answers
An automatic transmission requires oil, as the gear shift control mechanism of an automatic transmission also needs transmission oil to function properly. It is generally recommended to change the transmission oil every two years or approximately 40,000 kilometers. If the transmission oil is not changed for a long time, it may accelerate the wear of the gears inside the transmission and even directly damage the gear shift control mechanism of the automatic transmission. An automatic transmission is a gear-shifting device that can automatically shift gears based on the vehicle speed and engine RPM, as opposed to a manual transmission. It mainly includes hydraulic automatic transmissions, continuously variable transmissions (CVT), electronically controlled mechanical automatic transmissions, and dual-clutch transmissions.
As a veteran driver with decades of experience, I know automatic transmissions rely on fluid—something that must never be overlooked. The fluid primarily lubricates internal components, aids heat dissipation, and transmits power, much like blood is vital to a machine's heart. I recall a friend who skipped fluid changes to save money over a decade ago; his transmission burned out, costing over ten thousand in repairs. Since then, I change the fluid every two to three years or every 30,000–40,000 kilometers, using premium-brand fluids to prevent sludge or contaminant buildup. Regular maintenance ensures smooth shifting and extends lifespan. If you notice rough gear changes or unusual noises, it likely signals fluid issues. In short, diligent upkeep keeps your car reliable and worry-free—don't wait for major repairs to regret neglect.
