Abstract
A gear preselect system is provided for a transmission having dual input shafts in order to delay a gear preselect change until the last moment possible. The transmission controller determines the speed at which the next shift will occur and determines the preselect speed at which the preselect should occur in order for the preselect to take place prior to the time for shifting to the next gear. When the current vehicle speed is equal to or greater than the preselect speed, the transmission controller preselects the next higher gear.
