Automatic transmission fluid (ATF), a specialized hydraulic fluid, ensures proper operation, performance, and protection of automatic transmissions by lubricating gears, facilitating smooth gear changes, and cooling the transmission.
Lubrication:
ATF lubricates the various moving parts within the transmission, including gears, clutches, and bands, preventing wear and tear.
Hydraulic Function:
It acts as a hydraulic fluid, transmitting power from the engine to the transmission and enabling smooth and efficient gear changes.
Cooling:
ATF helps to cool the transmission by absorbing heat generated during operation, preventing overheating and damage.
Torque Converter Operation:
In automatic transmissions, ATF is crucial for the proper functioning of the torque converter, which transmits power from the engine to the transmission.
Valve Body Operation:
ATF ensures the smooth and precise operation of the valve body, which controls the flow of fluid to different parts of the transmission.
Clutch and Brake Band Friction:
ATF provides the necessary friction for the clutches and brake bands to engage and disengage smoothly, allowing for seamless gear changes.
Protection:
ATF protects the transmission from wear, corrosion, and oxidation, extending the lifespan of the transmission components.
Other Uses:
ATF is also used in some power steering systems, as a lubricant in select 4WD transfer cases, and in modern manual transmissions
