I'm not really good with this stuff, but this is what i understand of it:

I have attached a photo of our tranny from 2003. It used a dog shifter to shift between high and low gear. This is the part to the right of the picture that is attached to the pnuematic cylinder. As you can see, there are pins on the radial part of this shifting mechanism. These are on both sides of it. When pushed by the piston eigher way, these pins are engaged with holes of the same pattern in the gears. This shifter is what is attached to the output shaft, while the gears themselves rotate freely on the shaft. Now you have 2 possible ways to drive the output shaft, by shifting the dog gear into "low" or "high" gear.

PS... forgot to mention.. our tranny shifted between sprockets, not gears, if that was confusing at all
