Abstract: The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers, alkyl phosphites, specific ashless dispersants and a corrosion inhibitor. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent.
