Jeep 2007 Wrangler - Manual (Page 284)

NOTE: Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift the auto-
matic transmission to N (Neutral), hold foot on brake,
and turn the engine OFF. Make shift to desired mode.
NOTE: Shifting into or out of 4L is possible with the
vehicle completely stopped, however, difficulty may oc-
cur due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth align-
ment 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 position completely can cause
transfer case damage or loss of power and vehicle
control. You could have an injury accident. Do not
drive the vehicle unless the transfer case is fully
engaged.
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.
