2008 CHRYSLER 300 C transmission

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
operation.
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.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 position. 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
Brake Interlock Override
306 STARTING AND OPERATING

tab, which can be accessed through a hole inside the bin.
While the override is pressed, the shifter can be moved
out of the “P” (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.
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),
otherwise the load on the transmission locking mecha-
nism 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 “P” (Park) position on an automatic trans-
mission 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.

shifts, and the best fuel economy. Select the “3” range
when frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers.
NOTE:
•If the vehicle is started in cold temperatures, shifts into
Overdrive may be delayed. Normal Overdrive and
shifting operation will resume when the temperature
of the transmission reaches the appropriate tempera-
ture. Refer to the “Note” under “Torque Converter
Clutch” later in this section.
•If the transmission temperature gets too hot, the
transmission may downshift out of Overdrive or en-
gage overdrive at higher vehicle speeds until the
transmission cools down. After cooldown, Overdrive
will resume normal operation.“3” (Third)
This range eliminates shifts into Overdrive. The transmis-
sion 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 selections.
310 STARTING AND OPERATING

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
transmission.
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
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” (Neu-
tral) will continue 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 recom-
mend that you visit a dealer at your earliest possible
convenience. Your dealer has diagnostic equipment to
determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
5 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.

CAUTION!
Coasting the vehicle or driving for any other reason
with selector lever in NEUTRAL can result in trans-
mission damage.
WARNING!
Do not coast in “N” (Neutral) and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have an accident.“D” (Drive)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts and the best fuel economy.
The transmission automatically upshifts through fifth
gear. The “D” (Drive) position provides optimum driving
characteristics under all normal operating conditions.
When frequent transmission shifting occurs when using
the Overdrive range, such as when operating the vehicle
under heavy loading conditions (in hilly terrain, travel-
ing into strong head winds, or while towing heavy
trailers, use the AutoStick\2mode and select the “3”
range.
AutoStick\2Gear selection
The AutoStick\2feature can be selected by pressing the
selector lever to the right or the left with the lever in the
“D” (Drive) position. The gear currently selected is
indicated in the instrument cluster display. Briefly, press
