STARTING AND OPERATING 173
2H/4H AUTO TO 4H PART TIME OR 4H PART
TIME TO 2H/4H AUTO
Shifting between 2H/4H AUTO to 4H PART TIME
can be made with the vehicle stopped or in motion.
The preferred shifting speed would be 0 to 45 mph
(72 km/h). With the vehicle in motion, the transfer
case will engage/disengage faster if you
momentarily release the accelerator pedal after
completing the shift. Do not accelerate while
shifting the transfer case. Apply a constant force
when shifting the transfer case lever.
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. The front and
rear driveshaft speeds must be equal for the
shift to take place. Shifting while only the front
or rear wheels are spinning can cause damage
to the transfer case.
Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or
uneven tire pressures, excessive vehicle
loading, or cold temperatures.
Shifting effort will increase with speed, this is
normal.
During cold weather, you may experience
increased effort in shifting until the transfer case
fluid warms up. This is normal.
4H PART TIME/4H AUTO TO 4L OR 4L TO 4H
PART TIME/4H AUTO
With the vehicle rolling at 1 to 3 mph (2 to 5 km/h),
shift an automatic transmission into NEUTRAL (N),
or press the clutch pedal on a manual
transmission. While the vehicle is coasting at 1 to
3 mph (2 to 5 km/h), shift the transfer case lever
firmly to the desired position. Do not pause with
the transfer case in N (Neutral). Once the shift is
completed, place the automatic transmission into
DRIVE or release the clutch pedal on a manual
transmission.
NOTE:
Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty may occur
due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth
alignment and shift completion to occur. The
preferred method is with the vehicle rolling at 1 to
3 mph (2 to 5 km/h). Avoid attempting to engage
or disengage 4L with the vehicle moving faster
than 1 to 3 mph (2 to 5 km/h).
During cold weather, you may experience
increased effort in shifting until the transfer case
fluid warms up. This is normal.
TRAC-LOK REAR AXLE — IF EQUIPPED
The Trac-Lok rear axle provides a constant driving
force to both rear wheels and reduces wheel spin
caused by the loss of traction at one driving wheel.
If traction differs between the two rear wheels, the
differential automatically proportions the usable
torque by providing more torque to the wheel that
has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
WARNING!
Failure to engage a transfer case position
completely can cause transfer case damage or
loss of power and vehicle control. You could have
a collision. Do not drive the vehicle unless the
transfer case is fully engaged.
WARNING!
On vehicles equipped with a limited-slip
differential, never run the engine with one rear
wheel off the ground. The vehicle may drive
through the rear wheel remaining on the ground
and cause you to lose control of your vehicle.
