Abstract
In gear shift controlling method and apparatus for an automatic transmission, the automatic transmission comprising a plurality of frictional elements, a working liquid pressure for each of first and second frictional elements is controlled to make a gear shift in the automatic transmission in such a manner that while the first frictional element is released by a decrease pressure control for the working liquid pressure, the second frictional element is clutched by an increase pressure control for the working liquid pressure and a release capacity during an inertia phase during which the gear shift from a first gear range to a second gear range occurs is set in accordance with an instantaneous gear ratio during the inertia phase so as to output the release capacity set according to the instantaneous gear ratio.
