    摘要： The invention relates to a method for improving properties of protection against spalling of transmission lubricating compositions containing sulphur-containing and sulfur-phosphorous compounds comprising a step for adding into the initial transmission lubricating composition, compounds (c) reducing by at least 5% the active sulfur mass content, as measured by the ASTM D1662 standard, in the final composition.The invention also aims at a lubricating composition comprising: (a) from 60 to 90% by weight of one or more base oils, of mineral, synthetic or natural origin, (b) at least one anti-wear and extreme pressure phosphorous or sulfur-phosphorous additive, (c) at least one anti-wear and extreme pressure sulfur-containing additive, wherein: the ratio between the elementary sulfur mass content, as measured according to the ASTM D2622 standard, and the elementary phosphorus mass content, as measured according to the ASTM D5185 standard, S/P, of said lubricating composition, is comprised between 20 and 40, preferably between 25 and 35; the ratio between the active sulfur mass content at 150° C., as measured according to the ASTM D1662 standard, and the elementary sulfur mass content, as measured according to the ASTM D5185 standard, Sactive/S, of said lubricating composition, is less than 0.34, preferentially less than 0.33.
