flange to rotate in a reverse direction and the left output
piston, thereby causing the right-steer-clutch to engage
flange to rotate in a forward direction so that the vehicle

right steering will result. With the right-steer clutch
ring gears are driving the output planet carriers forward
engaged, the drive is from the turbine output shaft,
so that both output flanges are rotating in a forward

bevel gear. This bevel gear then drives the two engaged
driver for left steering, oil pressure is directed to the left-
bevel gears in opposite directions as shown in figure 24-
steer-clutch piston, engaging the left-steer clutch (fig.
