2007 DODGE MAGNUM automatic transmission

WARNING!
•Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in flash fire
causing serious personal injury.
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Un-
burned fuel could enter the catalytic converter and
once the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be
dangerous if done improperly. See section 6 of
this manual for the proper jump-starting proce-
dures and follow them carefully.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the key is
released. If this occurs, continue cranking up to 15
seconds with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the key once
the engine is running smoothly. Do not overspeed the
engine.
If the engine shows no sign of starting after two 15-
second periods of cranking with the accelerator pedal
held to the floor, the “NORMAL STARTING” procedure
should be repeated.
After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
210 STARTING AND OPERATING

ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 volt AC electrical outlet with a
grounded, three-wire extension cord.
The engine block heater cord is routed under the hood on
the driver side of the vehicle. It has a removable cap that
is located on the driver side of the Integrated Power
Module.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt electrical cord could
cause electrocution.
AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the
engine is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.

WARNING!
It is dangerous to shift the selector lever out of “P” or
“N” if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when
the engine is idling normally and when your right
foot is firmly on the brake pedal.
Automatic Transmission — General Information
The automatic transmission selects individual gears au-
tomatically, dependent upon:
•Altitude
•Vehicle Loading
•Driving Style
•Selector lever position
•Accelerator position
•Vehicle speedThe gear shifting process is continuously adapted, de-
pendent on the driving style, the driving situation and
the road characteristics.
NOTE:
•
After selecting any driving position, wait a moment to
allow the gear to engage fully before accelerating,
especially when the engine is cold.
•If there is a need to restart the engine, be sure to cycle
the key to the LOCK position before restarting. Trans-
mission engagement may be delayed up to 10 seconds
after restart if the key is not cycled to the LOCK
position first.
•The electronically controlled transmission provides a
precise shift schedule. The transmission electronics are
self-calibrating. Therefore, the first few shifts on a new
vehicle may be somewhat abrupt or soft until after the
break-in period. This is a normal condition, and pre-
cision shifts will develop within a few shift cycles.
212 STARTING AND OPERATING

The selector lever is automatically locked while in the P
(Park) position. To move the selector lever out of the P
(Park) position, the brake pedal must be firmly depressed
before the shift lock will release.
Shift the selector lever to the desired position only when
the engine is idling normally and the brake pedal is
applied. Do not release the brake until ready to drive. The
vehicle may otherwise accelerate quickly when the selec-
tor lever is in D (Drive) or R (Reverse) position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into P (Park), remove the key from
the ignition, and apply the parking brake. Once the
key is removed from the ignition, the transmission
selector lever is locked in the P (Park) position,
securing the vehicle against unwanted movement.
Furthermore, you should never leave children unat-
tended inside a vehicle.
Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission exceeds
normal operating temperature, the transmission will
change the way it shifts to help control the condition.
This may result in a slightly different feeling or response
during normal operation in D (Drive) position. After the
transmission cools down, it will return to normal opera-
tion.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a brake transmission shift
interlock system (BTSI) that holds the selector lever in the
P (Park) position when the ignition switch is in the LOCK
position. To move the selector lever out of the P (Park)
position, the ignition switch must be turned to the ON
position, and the brake pedal must be depressed.
STARTING AND OPERATING 213

For electrical system malfunctions, there is an override
for the interlock system. In order to override this system
the key must be in the ignition with the switch in the
ACC or ON positions. Remove the rubber storage tray
from the bin located to the right of the selector lever. The
override can be activated by pressing the pink-colored
tab, which can be accessed through a hole inside the bin.
While the override is pressed, the shifter can be movedout of the park position without pressing the brake. After
operation, return the rubber storage tray to its original
position.
4 Speed Automatic Transmission
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
selector lever between these gears.

214 STARTING AND OPERATING

Gear Ranges
P (Park)
P (Park) supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use P (Park) while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in
this range.
When parking on a flat surface, place the gear selector in
the P (Park) position first, and then apply the parking
brake.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of park. As
an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
The following indicators should be used to ensure that
you have engaged the selector lever into the P (Park)
position:
•When shifting into P (Park) move the lever all the way
forward until it stops, and is fully seated.
•Look at the shift indicator display on the instrument
panel to ensure it is in the P (Park) position.
CAUTION!
Damage to the shifter could result if the selector
lever is moved out of P (Park) before the ignition is
turned from the LOCK to ON position.

3 (Third)
This range eliminates shifts into Overdrive. The trans-
mission will operate normally in First, Second and
Third while in this range. The “3” position should also
be used when descending steep grades to prevent
brake system distress.
NOTE:
Using the “3” range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up.
L (Low)
This range should be used for engine braking when
descending very steep grades. In this range, upshifts
will occur only to prevent engine overspeed while
downshifts occur earlier than other gear range selec-
tions.
CAUTION!
Never race the engine with the brakes on and the
vehicle in gear, and never hold the vehicle on an
incline without applying the brakes. These practices
can cause overheating and damage to the transmis-
sion.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops, or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles (1.6–4.8 km) of driving). Because
engine speed is higher when the torque converter
STARTING AND OPERATING 217

clutch is not engaged, it may seem as if the transmis-
sion is not shifting into “Overdrive” when cold. This is
considered a normal condition. Pulling the selector
lever into the “3” position will show that the transmis-
sion is able to shift into and out of “Overdrive.”
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. P (Park), R (Reverse), and N (Neutral) willcontinue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into P (Park).
•Turn the key to LOCK then start the engine.
•Shift into D (Drive) and resume driving.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
