Abstract
The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers and phosphorus-containing compounds. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent and/or a polyol ester friction modifier.
