Abstract:
Design changes in automatic transmissions have resulted in new requirements for automatic transmission fluids. Electronic controls, for instance, perform best with fluids having better low-temperature properties.

Achievement of the target low-temperature properties can be accomplished in different ways. The advantages and disadvantages of each approach are discussed with respect to total fluid performance. Fluid performance properties examined include viscometrics, shear stability, antiwear and stability toward thermal stress and oxidation.
