Abstract
An apparatus for controlling a transmission having a synchromesh has a shifting actuator having an electric motor for shifting gears of the transmission. A load on the synchromesh is measured when shifting the gears of the transmission. A shifting stroke value for the shifting actuator when the measured load on the the synchromesh falls within a predetermined range is learned and stored. Based on the stored shifting stroke value, the electric motor of the shifting actuator is controlled when shfting the transmission gears.
