Choosing the Right Automatic Transmission Fluid
Automatic transmission fluid performs several critical functions within a transmission. In addition to lubricating gears, bearings and other moving components, it may operate hydraulic systems, transfer power through the torque converter, control clutch engagement and help remove heat from the transmission.
AMSOIL offers synthetic automatic transmission fluids for a wide range of passenger vehicles, performance applications, commercial vehicles and other equipment. Selecting the correct fluid depends on the transmission design and required specification rather than simply choosing a conventional or synthetic ATF.
Transmission Fluid Specifications Matter
Automatic transmissions are engineered around particular fluid characteristics, including viscosity, friction performance and compatibility with internal materials. Manufacturers therefore specify particular ATF standards for different transmissions, and fluids with similar appearance or viscosity should not automatically be considered interchangeable.
Specifications such as DEXRON, MERCON and manufacturer-specific requirements identify fluids designed to provide the characteristics required by particular transmission families. Always confirm the applicable specification before selecting a replacement fluid.
Heat and Transmission Protection
Heat is one of the major stresses placed on automatic transmission fluid. Towing, heavy loads, performance driving, stop-start operation and high ambient temperatures can increase transmission operating temperatures and accelerate lubricant degradation.
High-quality synthetic transmission fluid provides strong resistance to oxidation and thermal breakdown while maintaining dependable lubrication and hydraulic performance across changing operating temperatures.
Universal and Application-Specific Fluids
Some AMSOIL automatic transmission fluids are formulated to satisfy the requirements of numerous compatible transmission specifications, while other transmissions require more specialised fluids. A broader application range does not remove the need to verify compatibility with the particular transmission.
