Abstract: A system of selecting a transmission manual mode entry gear during transient driving conditions of an automobile vehicle includes a transmission in an automobile vehicle. An engine is connected to the transmission. A torque converter is connected to the transmission, and a differential provides drive output. A controller is in communication with the engine and the transmission. A shift device is in communication with the controller allowing manual selection by an operator of the automobile vehicle between a Park, a Reverse, a Neutral, a Drive and a Low or Manual (PRNDL) operating modes. A predicted gear is frozen close to a real gear at a time of entrance into the Manual mode.
