What is the viscosity of ATF?

The viscosity of Automatic Transmission Fluid (ATF) typically ranges from 5 to 10 centistokes (cSt) at 100°C, depending on the specific formulation and manufacturer. ATF is designed to provide optimal performance under various temperature conditions, ensuring smooth operation of the transmission system. Its viscosity can also change with temperature; it tends to be thinner at higher temperatures and thicker when cold. Always refer to the manufacturer's specifications for the exact viscosity of a particular ATF type.
