5. The transmission may include an electronically controlled Power Take-Off (PTO). The

PTO provides power to a hydraulic pump, which powers the 11K Self-Recovery Winch

(SRW) if equipped. The transmission will not shift from Neutral (N) if the PTO is

engaged and the winch switch is in the on position.

Transfer Case. The transfer case contains the gears and clutches that provide the

transmission with the seventh gear. The transfer case delivers power from the

transmission to the front driveshaft and rear driveshaft. In normal driving conditions the

transfer case splits the output torque of the transmission, providing 70 percent of the

torque to the rear and 30 percent to the front. In 1st gear, or any time the mode indicator

is illuminated, the output torque of the transmission is split evenly between front and rear.
