DEXRONŽ Brand Product Descriptions
DEXRONŽ Automatic Transmission Fluid (ATF)
Modern ATF typically contains a wide variety of chemical compounds intended to provide the required properties of a particular ATF specification. DEXRONŽ ATF contains the prescribed combination of additives that improve lubricating qualities for your GM Vehicle. These additives include anti-wear, rust and corrosion inhibitors, detergents, dispersants and surfactants (which protect and clean metal surfaces); viscosity modifiers, seal swell additives and agents (which extend the temperature range of the additives' application); and anti-foam additives and anti-oxidation compounds to inhibit oxidation and improve fluid stability.
DEXRONŽ offers two varieties of ATF, Standard DEXRONŽ-VI and DEXRONŽ-HP (High Performance), used in situations where low temperature fluidity and potential fuel economy are priorities.
