Abstract

Automatic transmission fluids are described which contain at least 0.05 weight percent of a dialkyl thiadiazole and sulfurized fat, sulfurized fatty acid, sulfurized fatty acid ester, up to about 0.15 weight % of a metal-containing detergent, and/or a mixture thereof. The transmission fluids according to the present invention exhibit improved anti-wear and extreme pressure performance.
