Abstract
The present invention provides a method for determining fill volumes of a plurality of clutch elements in an automatic transmission wherein each clutch element is applied in a predefined order and the fill volume of each clutch element is obtained by determining when the rotational speed of the engine varies from the rotational speed of the transmission's turbine by a predefined amount. The plurality of clutch elements comprises at least a 2C, 4C, UD, OD, and LR clutch element.
