Abstract
An auxiliary gear box for a transmission is provided including a piston housing having a first and second bore. First and second pistons are respectively arranged within the first and second bores and separate each of the first and second bores into two chambers. First and second shift shafts respectively extends from the first and second pistons and are each connected to shift forks. The exposed surface area of the piston in the chamber having the shift shaft is less than the exposed surface area of the piston on the chamber opposite the shift shaft. As a result, if both chambers of a bore are pressurized, the piston will move in the direction of the chamber having the shift shaft since a greater force will be generated on the piston in the chamber without the shift shaft. A three actuator arrangement is used to selectively actuate the pistons.
