Definitions

  • This invention relates to power transmitting fluids, particularly automatic transmission fluids, of enhanced performance capabilities.
  • Figure 1 depicts fluid acid number increase as a function of test cycles according to the General Motors DEXRON®-lll, 4L60 Cycling Test.
  • the mineral oils may be derived from refined, rerefined oils, or mixtures thereof.
  • Unrefined oils are obtained directly from a natural source or synthetic source (e.g., coal, shale, or tar sands bitumen) without further purification or treatment.
  • Examples of unrefined oils include a shale oil obtained directly from a retorting operation, a petroleum oil obtained directly from distillation, or an ester oil obtained directly from an esterification process, each of which is then used without further treatment.
  • Refined oils are similar to the unrefined oils except that refined oils have been treated in one or more purification steps to improve one or more properties.
  • the preferred synthetic oils are polyalphaolefins, diesters, and polyol esters as previously described having kinematic viscosities from 2 to 8, most preferably from 3 to 5 mm 2 /s when measured at 100°C.
  • Dl packages typically treat from 3 to 10 mass percent in the ATF.
  • the ATF additive package may also contain a viscosity modifier.
  • the additive is referred to as a combined package or DI ⁇ I.
  • DI ⁇ I An example of a DI/VI package is shown below:
  • Figure 3 shows 1-2 shift time as a function of cycles.
  • the lines in Figure 3 are shown as trend lines since the data has some variability. Fluids B and C actually fail the test due to elongating shift times so their trend lines rise with increasing cycles. Fluids A and D complete the test so their trend lines are of lower slope. Closer examination of the data indicates that the 1-2 shift times for Fluid D are the lowest and most consistent and thus represents the most desirable performance. The 1-2 shift times for Fluid A are quite variable.
