The transmission gear ratio is controlled by two clutches and two bands. This chart defines which clutches and bands are engaged for each of the transmission gears. A sprag is a one way clutch. Works similar to a ratchet or the gears on a 10 speed bike. It turns in one direction and freewheels in the other.
Not sure what a sprang is, possibly a southern version of a spring?
