Shifting Procedures
4H AUTO TO 4H PART TIME OR 4H PART TIME
TO 4H AUTO
Shifting between 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 2 to 3 mph (3 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
2 to 3 mph (3 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
2 to 3 mph (3 to 5 km/h). Avoid attempting to
engage or disengage 4L with the vehicle moving
faster than 2 to 3 mph (3 to 5 km/h).
FUEL SAVER TECHNOLOGY 6.4L
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and operation. The system is
automatic with no driver inputs. It is not available
in 4L. There is also a four cylinder indicator in the
instrument cluster to indicate when this feature is
active.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
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.
