What is Automatic Transmission Fluid?

[Ronald]

Automatic transmission fluid is a type of automatic transmission oil. Its function is to establish oil pressure through the oil pump to control the clutch and brake, enabling the automatic transmission to output power as required. Automatic transmission fluid has excellent lubrication and anti-wear properties, effectively reducing transmission vibration and wear. Below is more information about transmission fluid: Each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, rotational speed, and structure. Therefore, the original manufacturer specifies its own dedicated transmission fluid. Different transmission fluids are one of the factors affecting shift quality.

After driving for so many years, I know that automatic transmission fluid (ATF) is a specialized oil used in automatic transmissions. Its main functions are to lubricate gears, reduce friction, and assist the hydraulic system in transmitting power for smooth gear shifts. If not replaced in time, it can become dirty and thick, leading to issues like slipping during acceleration or jerky gear changes—I learned this the hard way and ended up spending thousands on repairs. Generally, it's recommended to check it every 20,000–30,000 kilometers or every two years to see if the fluid remains clear. There are different types on the market, such as DEXRON, so always cross-check your vehicle’s manual to choose the right specification and avoid damaging the transmission. Remember, regular maintenance extends your car’s lifespan and saves you money and hassle in the long run.

As someone who frequently repairs automatic transmission vehicles, automatic transmission fluid (ATF) is crucial: it's a specialized fluid designed for transmissions, serving hydraulic and lubrication functions, not ordinary engine oil. Its roles include cooling components and ensuring smooth valve body operation. Once degraded, ineffective fluid can cause serious issues like gear sticking or complete failure. I always remind owners to change it every 40,000 km or four years, preferably using manufacturer-recommended specifications like ATF-IV or MERCON LV. Never compromise with cheap, inferior products—if discoloration or sediment is detected during inspection, immediate action is needed to avoid costly overhauls. Simple maintenance can prevent unexpected troubles.

Automatic transmission fluid (ATF) is the specialized working fluid for automatic transmission vehicles, somewhat akin to blood's role in the body, ensuring smooth transmission operation. Regular replacement is crucial. I've developed the habit of having the shop check the fluid condition during every maintenance service, as aging can reduce shifting efficiency and make driving uncomfortable. Typically, ATF should be replaced every three years or 30,000 kilometers. Check the dipstick to ensure there's no fluid loss. Maintaining this routine helps prevent minor issues and enhances driving safety.

Neglecting automatic transmission fluid maintenance can lead to major issues: it is the core of the hydraulic system, responsible for gear shifting. Once deteriorated or leaked, reduced pressure can cause loss of control and slippage, endangering safety. I personally experienced a transmission overheating breakdown, costing nearly ten thousand yuan in repairs. It's essential to change the fluid as recommended in the vehicle manual, inspect and replace it every 40,000 kilometers, ensuring the oil is clear and odorless. This ensures more reliable driving and avoids unnecessary risks and expenses.
