ATF is not just a lubricant, it is also a medium for hydraulic power transmission. In an automatic transmission, it simultaneously undertakes the following four key tasks:
Power transmission: Transfer engine power to the gearbox in the torque converter.
Lubrication and cooling: Reduce friction between gears and bearings, and remove heat generated internally.
Friction control: Ensure smooth engagement of clutch plates during gear shifting to avoid shaking.
Cleaning and rust prevention: Clean the debris generated by friction and protect the precision solenoid valve system.
