摘要:
There is provided an automatic transmission fluid composition comprising a major amount of a base oil; one or more friction modifiers, wherein total nitrogen content provided by the one or more friction modifiers is greater than or equal to about 300 ppm; and one or more ashless dispersants, wherein the total nitrogen content provided by the one or more ashless dispersants is greater than or equal to about 500 ppm. The automatic transmission fluid may have a kinematic viscosity at 100° C. of from about 4 cSt to about 6.5 cSt and a Brookfield viscosity at −40 ° C. of from about 4,000 cP to about 20,000 cP.
