Abstract

A method for controlling automatically controlling the shifting of a transmission when operating the higher speeds so that a downshift is performed before a directional shift is made. A controller receives a directional signal, a mode signal, a transmission output speed signal. The signals and a shift sequence table is used to shift the transmission when the machine has reached an "on speed" point. The controller will perform a shift after a predetermined time without the machine reaching the "on speed" point.
