2011 Ram 3500 Diesel Supplement

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL position into another gear range.
PARK
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use PARK while the vehicle is in motion. Apply
the parking brake when leaving the vehicle in this range.
Always apply the parking brake first, then place the shift
lever into the PARK position. On four-wheel drive ve-
hicles be sure that the transfer case is in a drive position.
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
movement and possible injury or damage.(Continued)
WARNING! (Continued)
•Your vehicle could move and injure you and others
if it is not completely in PARK. Check by trying to
move the shift lever back and forth without first
pulling it toward you after you have set it in
PARK. Make sure it is in PARK before leaving the
vehicle.
•It is dangerous to move the shift lever out of PARK
or NEUTRAL 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 reverse. 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 foot is firmly on the brake pedal.
REVERSE
This range should be used only after the vehicle has come
to a complete stop.
64 STARTING AND OPERATING

NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range provides underdrive first, second and third
gears, direct fourth gear and overdrive fifth and sixth
gears. The shift into overdrive fifth and sixth gear occurs
only after the transmission has completed the shift into
fourth gear. No other movement of the shift mechanism
is required to complete the 4–5 or 5–6 gear shifts.
Upshifts into both overdrive gears, fifth and sixth, will be
delayed when the transmission fluid temperature is
below 40°F (4.5°C) or above 240°F (115.5°C).NOTE:
Use caution when operating a heavily loaded
vehicle in second or first gear in high ambient tempera-
tures as torque converter slip can impose significant
additional heat load on the cooling system.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fifth and sixth (Overdrive). The
transmission will automatically shift from DRIVE to
Overdrive if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 30 mph
(48 km/h);
•the “TOW/HAUL” switch has not been activated;
4
STARTING AND OPERATING 65

•transmission has reached normal operating
temperature.
NOTE: If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable level. Refer to the “Note” under
“Torque Converter Clutch” later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the “Transmission
Temperature Warning Light” may illuminate and the
transmission may downshift out of Overdrive until the
transmission cools down. After cool down, the transmis-
sion will resume normal operation. The transmission will downshift from Overdrive to
DRIVE if the accelerator pedal is fully pressed at vehicle
speeds above approximately 35 mph (56 km/h).
When To Use TOW/HAUL
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the “TOW/HAUL” switch once to select
“TOW/HAUL.” In “TOW/HAUL” mode, fourth to fifth
gear upshifts are delayed. Shifts into fifth and sixth gear
are still allowed under steady cruise conditions. Closed
throttle downshifts (for improved engine braking) may
occur during steady braking maneuvers. Pressing the
switch a second time restores normal operation. Normal
operation is always the default at engine start-up.
66 STARTING AND OPERATING

The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate when the switch has been
activated. If the “TOW/HAUL” modes are desired, the
button must be pressed each time the engine is started.
Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:
•The torque converter clutch will not engage, and the
transmission will not shift to sixth gear, until the
transmission fluid and engine coolant are warm [usu-
ally after 1-3 miles (1.6 - 4.8 km) of driving]. Because
sixth gear is disabled, and engine speed is higher
when the torque converter clutch is not engaged, it
may seem as if the transmission is not shifting prop-
erly when cold. This is normal. Using the Electronic
Range Select (ERS) feature, when the transmission is
TOW/HAUL Switch

sufficiently warm, will demonstrate that the transmis-
sion is able to shift into and out of Overdrive.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds of shifting from
PARK into any other gear position.
Automatic Transmission with Overdrive (AS68RC)
– If Equipped (Chassis Cab Only)
The shift lever display located in the instrument panel
cluster, indicates the transmission gear range (the selector
is illuminated for night driving). The shift lever is
mounted on the right side of the steering column. You
must press the brake pedal to pull the shift lever out of
PARK position (Brake Interlock System). To drive, movethe shift lever from PARK or NEUTRAL to the desired
DRIVE position. Pull the shift lever toward you when
shifting into REVERSE or PARK.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows
you to move the switch down (-) or up (+) when the
shifter is in the D (Drive) position, allowing the selection
of the desired top gear. For example, if the driver shifts
the transmission into third gear, the transmission will
never shift above third gear, but can shift down into
second or first gear, when needed.
68 STARTING AND OPERATING

Switching from ERS to D-Mode can be done at any
vehicle speed. To switch from “Drive” mode to “ERS”
mode, press the switch down (-) once. The current gear
will be maintained as the top gear. To disable ERS, simply
press and hold the switch up (+) until “D” is displayed in
the instrument cluster odometer.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.

70 STARTING AND OPERATING

REVERSE
This range should be used only after the vehicle has come
to a complete stop.
NEUTRAL
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Set the parking brake if you must
leave the vehicle.
DRIVE
This range provides all forward gears, including fourth
gear direct, fifth and sixth. Use this range for most city
and highway driving. Upshifts into both overdrive gears,
fifth and sixth, will be delayed when the transmission
fluid temperature is between -4°F (-20°C) and 41°F (5°C).
During very cold conditions when the transmission fluid
is below -4°F (-20°C), the transmission will be limited to
third gear. Normal operation will return after the trans-
mission fluid warms up.NOTE:
Use caution when operating a heavily loaded
vehicle in second or first gear selections in high ambients
as torque converter slip can impose significant additional
heat load on the cooling system.
Overdrive Operation
The Overdrive automatic transmission contains an elec-
tronically controlled fifth and sixth gear. The transmis-
sion will automatically shift from DRIVE to fifth or sixth
gear if the following conditions are present:
•the shift lever is in DRIVE;
•the engine coolant has reached normal operating tem-
perature;
•vehicle speed is above approximately 38 mph
(61 km/h) for fifth gear and 50 mph (80 km/h) for
sixth gear;
•the “TOW/HAUL” switch has not been activated
(sixth gear is inhibited in “TOW/HAUL” mode);
