Abstract
A shift mode selector for an automatic transmission of a vehicle drive train including an engine, includes a first shift point map for an automatic shift in an automatic shift mode and a second shift point map in a manual shift mode. An input device produces an operator mode change demand from the manual shift mode to the automatic shift mode. A controller determines whether or not a potential downshift demand is available upon effecting a mode change demanded by said operator mode change demand. The controller prohibits the mode change when said potential downshift demand is available, and produces a gear ratio control signal in accordance with the second shift point map unless a predetermined condition is met. The gear ratio control signal is applied to a gear ratio actuator for establishing various gear ratios in the automatic transmission.
