METHOD FOR LUBRICATING A CLUTCH-ONLY AUTOMATIC TRANSMISSION COMPONENT REQUIRING LUBRICATION |
摘要 |
The present disclosure provides a fluid for lubricating the clutch-only portion of a wet clutch in a dual clutch transmission. The fluid provides high dynamic friction durability and comprises an oil of lubricating viscosity formulated with additive components comprising: i) at least one metal detergent; ii) at least one phosphorus-based wear preventative; iii) a phosphorylated and boronated dispersant different than the at least one phosphorus-based wear preventative; iv) a sulfurized extreme pressure agent; and a ratio between the content (ppm) of the sulfur based on the total weight of the fluid composition and a content (ppm) of phosphorus based on the total weight of the fluid composition ranging from about 2.0 to about 0.5 (ppm/ppm).
