transmission DODGE CHARGER SRT 2015 7.G Service Manual

In AutoStick mode, the transmission will shift up or
down when (+/-) is manually selected by the driver
(using the shift lever, or the shift paddles), 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.
•In temporary AutoStick mode (shift lever in DRIVE),
the transmission will automatically shift up when
maximum engine speed is reached. Lack of accelerator
pedal activity will cause the transmission to revert to
automatic operation.
•If normal AutoStick mode is engaged (shift lever in
MANUAL position), manual gear selection will be
maintained until the shift lever is returned to DRIVE,
or as described below. The transmission will not
upshift automatically at redline in this mode, nor will
downshifts be obtained if the accelerator pedal is
pressed to the floor.
•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.
•The system will ignore attempts to upshift at too low
of a vehicle speed.
386 STARTING AND OPERATING

•Holding the (-) paddle depressed, or holding the shift
lever in the (-) position, will downshift the transmis-
sion 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, return the shift lever to the
DRIVE position, or press and hold the (+) shift paddle (if
the shift lever is already in DRIVE) until “D” is once
again indicated in the instrument cluster. You can shift in
or out of the 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.
DRIVE MODES
Your SRT vehicle is equipped with a SRT Drive Mode
feature. This feature gives the driver control over the
systems in the vehicle which affect its performance,
enabling the driver to tune it for desired driving sce-
narios. Below are the modes of operation:

•The vehicle will restart with VALET active if VALET
was active when the vehicle was last shut down.
•Eco (Automatic Transmission only) — Eco modifies
the vehicle’s engine and transmission settings to pro-
vide improved fuel economy at a trade-off with accel-
eration performance. Increased engine exhaust noise
and/or vibration may be noticed while Eco is active,
this is normal and will not damage the vehicle.
NOTE:Changing the Drive Mode will deactivate Eco.
Launch Mode — If Equipped
This vehicle is equipped with a Launch Control system
that is designed to allow the driver to achieve maximum
vehicle acceleration in a straight line. Launch Control is a
form of traction control that manages tire slip while
launching the vehicle. This feature is intended for use
during race events on a closed course where consistent
quarter mile and zero to sixty times are desired. The
system is not intended to compensate for lack of driver
experience or familiarity with the race track. Use of this
feature in low traction (cold, wet, gravel, etc.) conditions
may results in excess wheel slip outside this systems
control resulting in an aborted launch.
NOTE:Launch mode is not available within the first 500
miles of engine break-in.
Preconditions:
•Launch control should not be used on public roads.
Always check track conditions and the surrounding
area.
•Launch Control is not available for the first 500 miles
of the vehicle’s life.
•Launch Control should only be used when the engine
and transmission are at operating temperature.
392 STARTING AND OPERATING

9. Keep the vehicle pointed straight.
Launch control will be active until the vehicle reaches
62 mph (100 km/h), at which point the ESC system will
return to its current ESC mode.
Launch control will abort before launch completion,
display “Launch Aborted” in the cluster and return to
ESC Full ON under any the following conditions:
•The accelerator pedal is released during launch. ESC
system continues in ESC Full ON.
•The ESC system detects that the vehicle is no longer
moving in a straight line. ESC system continues in ESC
Full ON.
•The “ESC OFF” button is pressed to change the system
to another mode. One press puts the ESC system into
ESC Full ON.
NOTE:After launch control has been aborted, ESC will
return to its current ESC mode.
CAUTION!
Do not attempt to shift when the drive wheels are
spinning and do not have traction. Damage to the
transmission may occur.
Guidelines For Track Use
NOTE:Because of the extreme conditions encountered
during track use, any damage or wear associated with
track use is not covered by warranty.
•If your SRT vehicle is equipped with Drive Modes they
will alter the vehicle’s performance in various driving
situations. It is recommended that your vehicle oper-
ates in SPORT or TRACK modes during the track
event.
394 STARTING AND OPERATING

•Prior to each track event/day, verify all fluids are at
the correct levels. Refer to “Fluid Capactites” in Main-
taining Your Vehicle for further information.
•Prior to each track event, verify the front and rear
brake pads have more than½pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
•At the conclusion of each track event, it is recom-
mended that a brake bleed procedure is performed to
maintain the pedal feel and stopping capability of your
Brembo High Performance brake system.
•It is recommended that each track outing should end
with a minimum of 1 cool down lap using minimal
braking.
•If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during
warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
•All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion system, brake system, prop shaft, and½shaft
boots should be checked for wear or damage after
every track event.
•Track usage results in increased operating tempera-
tures of the engine, transmission, clutch – if equipped,
driveline and brake system. This may affect noise
(NVH) countermeasures designed into your vehicle.
New components may need to be installed to return
the system to the original NVH performance.
•Tire pressure:
•40psi hot, recommend 32psi front, 30psi rear cold

STARTING AND OPERATING 395

NOTE:
•When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
•This light only shows that the parking brake is ap-
plied. It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking
brake before placing the shift lever/gear selector in
PARK, otherwise the load on the transmission locking
mechanism may make it difficult to move the shift
lever/gear selector out of PARK. The parking brake
should always be applied whenever the driver is not in
the vehicle.
WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
•When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the shift lever/gear selector.
