ABSTRACT:
This invention relates to a composition, comprising: (A) a Mannich dispersant having a base number in the range of about 45 to about 90; (B) a boron compound; and (C) an organic phosphorus acid or ester, or derivative of said phosphorus acid or ester. In one embodiment, this composition further comprises (D) a thiocarbamate. In one embodiment, this composition further comprises (E) a nitrogen-containing ester of a carboxy-containing interpolymer. These compositions are useful as additives for lubricants and functional fluids, and are particularly useful as additives for automatic transmission fluids for enhancing the torque characteristics such automatic transmission fluids.
