Trucking: Super 10 transmission, clutch pedal, forward momentum

Question
Briefly describe how to properly up and downshift a super 10 transmission.  Is it necessary to use the clutch when using the selector button?

Answer
A super 10 is basically set up like an automobile 5 speed transmission in whaich all of the gears are split. No it is not neccessary to use the clutch pedal when using the high range selector knob. This transmission feature operateas strictly on centrifugal force and the weighht of the vehicle and forward momentum are what make the shift possible.
