transmission DODGE CHALLENGER SRT 2016 3.G Service Manual

Extreme Cold Weather (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.

WARNING! (Continued)
•If the vehicle has a discharged 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. Refer
to “Jump-Starting” in “What To Do In Emergen-
cies” for further information.

After Starting
The idle speed is controlled automatically and it will
decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, 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 must be plugged in at least one
hour to have an adequate warming effect on the engine.
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 near the air box.
WARNING!
Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.

MANUAL TRANSMISSION — IF EQUIPPED
Six-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the vehicle,
especially on an incline.
CAUTION!
•Never drive with your foot resting on the clutch
pedal, or try to hold the vehicle on a hill with the
clutch pedal partially engaged, as this will cause
abnormal wear on the clutch. Refer to “Electronic
(Continued)
CAUTION! (Continued)
Brake Control System/Hill Start Assist” in “Start-
ing And Operating” for further information.
• Failure to press the clutch pedal fully to the floor
may cause increased shift efforts, and may result in
damage to the clutch and transmission.
• Do not rest your hand on the gear selector while
driving, as this may result in transmission synchro-
nizer damage.
• Do not attempt to shift the transmission if the rear
wheels are spinning due to loss of traction. Dam-
age to the transmission may occur.
NOTE: During cold weather, you may experience in-
creased effort in shifting until the transmission fluid
warms up. This is normal.

STARTING AND OPERATING 383

NOTE:
•Your vehicle is equipped with a transmission reverse
inhibitor system. When vehicle speed is greater than
3 mph (5 km/h), the reverse inhibitor activates to help
prevent shifts into REVERSE. When at a complete stop,
you may notice lighter shift efforts into REVERSE with
the ignition switch in the ON position (RUN position
for Keyless Enter-N-Go) as compared to the LOCK
position (OFF position for Keyless Enter-N-Go). This is
normal operation of the transmission reverse inhibitor
system.
• Due to the high performance nature of your drivetrain,
you may hear your transmission. This can be most
noticeable when the vehicle is idling in NEUTRAL
with the clutch engaged (clutch pedal released), but it
may also be heard when driving at low engine RPM.
Manual Shifter
384 STARTING AND OPERATING

Also, this may be more noticeable when the transmis-
sion is warm. This is a normal condition and is not an
indication of a problem with your clutch or transmis-
sion.
Shifting
Fully press the clutch pedal and lift your foot off the
accelerator pedal before shifting gears. As you release the
clutch pedal, lightly press the accelerator pedal. Damage
to the transmission or clutch may occur if you do not
fully press the clutch pedal and lift off of the accelerator
pedal when shifting.
The six-speed manual transmission has a spring that
centers the gear selector near third and fourth gear. This
spring helps you know which gear you are in when you
are shifting. Be careful when shifting from first to second
or downshifting from sixth to fifth.The spring will try to pull the gear selector toward third
and fourth gear. Make sure you move the gear selector
into second or fifth gear. If you let the gear selector move
in the direction of the pulling, you may end shifting from
first to fourth or from sixth to third gear.CAUTION!
Always make sure the vehicle comes to a complete
stop before shifting into REVERSE. Failure to do so
may result in transmission damage.
You must always use first gear (or REVERSE) when
starting from a standing position.5
STARTING AND OPERATING 385

Recommended Shift Speeds
To utilize your manual transmission efficiently for fuel
economy, it should be upshifted as listed in recom-
mended shift speed chart.
MANUAL TRANSMISSION RECOMMENDED SHIFT SPEEDS
Engine 1-44-5 5-6
6.2L Supercharged mph2025 42
(km/h) (32)(40) (67)
6.4L mph 2037 48
(km/h) (32)(59) (77)
Earlier upshifts during cruise conditions (relatively
steady speeds) may result in increased fuel economy.
Higher upshift speeds may be used to obtain a desired
acceleration rate.
1–4 Skip Shift
There are times when you must shift the transmission
directly from first gear to fourth gear instead of from first
gear to second gear. This is to help you get the best
possible fuel economy from your vehicle. This occurs
when the engine coolant (antifreeze) is higher than 106°F
386 STARTING AND OPERATING

(41°C), vehicle speed is greater than 19 mph (30 km/h)
but less than 21 mph (34 km/h), and the transmission is
in first gear, and the accelerator is at ¼ throttle or less.
After you shift the transmission to fourth gear, you can
press the clutch in and shift to another forward gear.
Downshifting
To maintain a safe speed and prolong brake life, down-
shift to maintain a safe speed when descending a steep
grade.
WARNING!
Skipping more than one gear while downshifting,
could cause you to lose control of your vehicle. You
could have a collision.
CAUTION!
•If you skip more than one gear while downshifting
or downshift at too high an engine speed, you
could damage the engine, transmission, or clutch.
• Do not downshift into first gear when the vehicle is
moving faster than 15 mph (24 km/h), as you could
damage the engine and/or clutch.
AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or NEUTRAL
if the engine speed is higher than idle speed. If
your foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit

WARNING!(Continued)
someone or something. Only shift into gear when
the engine is idling normally and your foot is
firmly pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always shift the
into PARK or the manual transmission into FIRST
gear or REVERSE, apply the parking brake, turn
the engine OFF, remove the key fob from the
vehicle and lock your vehicle. When the ignition is
in the OFF mode, the automatic transmission is
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always make sure the
ignition is in the OFF mode, remove the Key Fob
from the vehicle, and lock the vehicle.
(Continued)
WARNING! (Continued)
•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 transmission gear selector.
• Do not leave the Key Fob in or near the vehicle (or
in a location accessible to children), and do not
leave the ignition in the ACC or ON/RUN mode. A
child could operate power windows, other controls,
or move the vehicle.
388 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
• Do not shift between PARK, REVERSE, NEU-
TRAL, or DRIVE when the engine is above idle
speed.
• Before shifting into any gear, make sure your foot
is firmly pressing the brake pedal.
NOTE: You must press and hold the brake pedal while
shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the engine can be turned off. This helps the driver
avoid inadvertently leaving the vehicle without placing
the transmission in PARK. This system also locks the
transmission in PARK whenever the ignition switch is in
the OFF position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the gear selector in
PARK unless the brakes are applied. To shift the trans-
mission out of PARK, the engine must be running and the
brake pedal must be pressed.
The brake pedal must also be pressed to shift from
NEUTRAL into DRIVE or REVERSE when the vehicle is
stopped or moving at low speeds.

Eight-Speed Automatic Transmission — If
Equipped
The transmission gear range (PRNDM) is displayed both
on the gear selector and in the Driver Information
Display (DID).
To select a gear range, press the lock button on the gear
selector and move the lever rearward or forward. You
must also press the brake pedal to shift the transmission
out of PARK, or to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds (refer to “Brake/Transmission Shift Interlock Sys-
tem” in this section). Select the DRIVE range for normal
driving.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. This is a normal
condition, and precision shifts will develop within a few
hundred miles (kilometers).
