Abstract
A method for controlling automatic transmission downshift phases. The method determines conditions in which the downshift passes from normal operating conditions based on predetermined passage laws to special downshift operating conditions, and senses the passage to the special operating conditions. On sensing the passage to the special operating conditions, downshifting is effectuated by passing from the current gear ratio to a lower gear ratio, and blocking the lower gear ratio until the special downshift operating conditions disappear.
