Abstract
Provided is a method of setting a neutral position of each speed-range shift rail for accurate gear-shifting in a transmission gear actuator. The method includes a reference neutral position determination step of determining a reference neutral position as an absolutely neutral position by reciprocating a shift finger in a free-range shift rail, and a speed-range neutral position determination step of determining a neutral position of each speed-range shift rail by reciprocating a control finger in the speed-range shift rail. Since the neutral position of each speed-range shift rail is set through the above method, it is possible to perform more accurate gear-shifting and prevent incomplete gear engagement by performing the gear-shifting at the neutral position of each speed-range shift rail.
