Abstract
A method of adapting transmission controls to locate synchronizer touch points in an automated layshaft transmission. This method may include actuating a motor to move a shift drum along a layshaft at an essentially constant speed; measuring a feedback current as the motor moves the shift drum; detecting a first spike in feedback current adjacent to a second spike in feedback current for a gear; determining a shift drum angle for the first spike; and adjusting a transmission controller to set a synchronizer touch point at a shift drum angle adjacent to the first feedback current spike for the gear.
