2015 DODGE DURANGO engine

When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing heavy trailers), use the AutoStick shift
control (refer to AutoStick in this section for further
information) to select a lower gear. Under these condi-
tions, using a lower gear will improve performance and
extend transmission life by reducing excessive shifting
and heat buildup.
During cold temperatures, transmission operation may
be modified depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch is inhibited until the transmission fluid
is warm. Normal operation will resume once the trans-
mission temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all.
Vehicle performance may be severely degraded and the
engine may stall. In some situations, the transmission
may not re-engage if the engine is turned off and
restarted. The Malfunction Indicator Light (MIL) may be
illuminated. A message in the instrument cluster will
inform the driver of the more serious conditions, and
indicate what actions may be necessary.

STARTING AND OPERATING 437

In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:
NOTE:In cases where the instrument cluster message
indicates the transmission may not re-engage after en-
gine shutdown, perform this procedure only in a desired
location (preferably, at your authorized dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If not,
shift the transmission to NEUTRAL.
3. Press and hold the ignition switch until the engine
turns OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no
longer detected, the transmission will return to normal
operation.
NOTE:Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your
earliest possible convenience. Your authorized dealer has
diagnostic equipment to determine if the problem could
recur.
If the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
438 STARTING AND OPERATING

can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
When the transmission is in DRIVE, it will operate
automatically, shifting between the eight available gears.
To engage AutoStick, simply tap one of the steering
wheel-mounted shift paddles (+/-). Tapping (-) to enter
AutoStick mode will downshift the transmission to the
next lower gear, while using (+) to enter AutoStick mode
will retain the current gear. When AutoStick is active, the
current transmission gear is displayed in the instrument
cluster.
In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver,
unless an engine lugging or overspeed condition would
result. It will remain in the selected gear until another
upshift or downshift is chosen, except as described
below.
•The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
•The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
•You can start out, from a stop, in first or second gear.
Tapping (+) at a stop will allow starting in second gear.
Starting out in second gear can be helpful in snowy or
icy conditions.
•If a requested downshift would cause the engine to
over-speed, that shift will not occur.
5
STARTING AND OPERATING 439

•The system will ignore attempts to upshift at too low
of a vehicle speed.
•Holding the (-) paddle depressed will downshift the
transmission to the lowest gear possible at the current
speed.
•Transmission shifting will be more noticeable when
AutoStick is engaged.
•The system may revert to automatic shift mode if a
fault or overheat condition is detected.
To disengage AutoStick mode, press and hold the (+)
shift paddle until#D#is once again indicated in the
instrument cluster. You can shift in or out of AutoStick
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
ALL-WHEEL DRIVE OPERATION
Single-Speed Operating Instructions/Precautions
— If Equipped
This system contains a single-speed (HI range only)
transfer case, which provides convenient full-time all-
wheel drive. No driver interaction is required. The Brake
Traction Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
440 STARTING AND OPERATING

If One Or More Shift Conditions Are Not Met:
1. The indicator light for the current position will remain
ON.
2. The newly selected position indicator light will con-
tinue to flash.
3. The transfer casewill notshift.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new transfer
case position have been met. To retry the selection, turn
the control knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to the#Shifting Procedure#for your transfer
case, located in this section of the owner’s manual.
The “SERV AWD” Warning Light monitors the electronic
shift all-wheel drive system. If this light remains on after
engine start up or illuminates during driving, it means
that the all-wheel drive system is not functioning prop-
erly and that service is required.
WARNING!
Always engage the parking brake when powering
down the vehicle if the “SERV AWD Warning Light”
is illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.
NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in LOW RANGE, the
engine speed is approximately three times that of the
AWD AUTO position at a given road speed. Take care not
to overspeed the engine and do not exceed 25 mph
(40 km/h).

Neutral (N)
Neutral – This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting And Operating” for further infor-
mation.
Shifting Procedure
NOTE:
•If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The position indicator light for the previous posi-
tion will remain ON and the newly selected position
indicator light will continue to flash until all the require-
ments for the selected position have been met. To retry a
shift: return the control knob back to the original posi-
tion, make certain all shift requirements have been met,
wait five seconds and try the shift again.
•If all the requirements to select a new transfer case
position have been met, the current position indicator
light will turn OFF, the selected position indicator light
will flash until the transfer case completes the shift.
When the shift is complete, the position indicator light
for the selected position will stop flashing and remain
ON.
AWD Auto To Low Range
NOTE:When shifting into or out of LOW RANGE some
gear noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) or completely stopped. Use either of
the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to
3 mph (3 to 5 km/h).
5
STARTING AND OPERATING 445

2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the AWD control switch to
the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition switch in ON/ RUN position and
engine running, shift the transmission to Neutral.
3. Rotate the AWD control switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission back into gear.
NOTE:
•If Steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied prior to attempting the shift
or if they no longer are being met while the shift
attempt is in process, the desired position indicator
light will flash continuously while the original position
indicator light is ON, until all requirements have been
met.
•The ignition switch must be in the RUN position for a
shift to take place and for the position indicator lights
to be operable. If the ignition switch is not in the RUN
position, then the shift will not take place and no
position indicator lights will be on or flashing.
