Abstract

An improved control, which dynamically adjusts the shift control parameters in response to an indication of the driving style of the vehicle operator. The driving style indication is used to form a dynamic shift factor DSF, which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a shift control parameter uniquely suited to the driving style of the operator of the vehicle.
