Trac-Lok Rear Axle - If Equipped - Jeep WRANGLER 2020 Owner's Manual

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 PT/4H Auto To 4L Or 4L To 4H PT/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).
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.
STARTING AND OPERATING
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!
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.
