An improved control, which dynamically adjusts the shift control parameters in response to the driving habits of the operator, as judged by an indication of the average peak acceleration during specified operation of the vehicle. To determine the indication of average peak acceleration, the longitudinal acceleration of the vehicle is continuously determined in the course of vehicle operation. The peak acceleration values occurring in successive ratio-dependent time intervals are identified and accumulated to form cumulative and average peak acceleration terms. The average peak acceleration term is used to form a dynamic shift factor which is used to ratiometrically schedule the shift pattern, line pressure and desired shift time between predefined Normal and Performance values to provide a continuum of shift control parameters uniquely suited to the driving style of the operator of the vehicle.
