ATF is a specialized hydraulic fluid crucial for automatic transmissions, performing multiple jobs: it transmits power via the torque converter, lubricates and cools internal components (gears, clutches, bands), cleans deposits, and provides hydraulic pressure for shifting. Unlike engine oil, ATF has specific requirements for viscosity, thermal stability, and friction modification.
Key Functions of ATF
Power Transmission: Acts as a hydraulic fluid in the torque converter to transfer engine power to the gearbox.
Lubrication & Cooling: Reduces friction and dissipates the intense heat generated by moving parts, preventing premature wear.
Hydraulic Pressure: Moves pistons and valves within the transmission for smooth gear changes.
Cleaning: Suspends contaminants like sludge and varnish, carrying them to the filter.
Friction Control: Contains additives to ensure the right amount of grip and slip for clutches and bands.
Using the wrong fluid can lead to poor shifting, overheating, and severe transmission damage, so we recommend our ATF product for your safety.
