3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.
NOTE: Even if the transmission can be reset, we recom-
mend that you visit your authorized dealer at your earliest
possible convenience. Your authorized dealer has diagnos-
tic equipment to determine if the problem could recur.
If the transmission cannot be reset, authorized dealer
service is required.
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the trans-
mission is in DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the transmission will not
shift above fourth gear, but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE position, the transmission will operate automatically, shift-
ing between all available gears. Tapping the ERS (-) switch
will activate ERS mode, display the current gear in the
instrument cluster, and set that gear as the top available
gear. Once in ERS mode, tapping the ERS (-) or (+) switch
will change the top available gear.
To exit ERS mode, simply push and hold the ERS (+) switch
until the gear limit display disappears from the instrument
cluster.

NOTE: To select the proper gear position for maximum
deceleration (engine braking), simply push and hold the
ERS (-) switch. The transmission will shift to the range
from which the vehicle can best be slowed down.
CAUTION!
When using ERS for engine braking while descending
steep grades, be careful not to overspeed the engine.
Apply the brakes as needed to prevent engine over-
speed.
Overdrive Operation
The automatic transmission includes an electronically con-
trolled Overdrive (fifth and sixth gears). The transmission
will automatically shift into Overdrive if the following
conditions are present:
• The gear selector is in the DRIVE position.
• The transmission fluid has reached an adequate tem-
perature.
• The engine coolant has reached an adequate tempera-
ture.
• The vehicle speed is sufficiently high.
• The driver is not heavily pressing the accelerator.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting occurs,
push the TOW/HAUL switch to activate TOW/HAUL
mode. This will improve performance and reduce the
potential for transmission overheating or failure due to
excessive shifting. When operating in TOW/HAUL mode,
transmission upshifts are delayed, and the transmission
148 STARTING AND OPERATING
will automatically downshift (for engine braking) when the
throttle is closed and/or during steady braking maneu-
vers.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default
at engine start-up. If TOW/HAUL mode is desired, the
switch must be pushed each time the engine is started.WARNING!
Do not use the “TOW/HAUL” feature when driving in
icy or slippery conditions. The increased engine brak-
ing can cause the rear wheels to slide, and the vehicle
to swing around with the possible loss of vehicle
control, which may cause an accident possibly result-
ing in personal injury or death.
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 automatically
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 some
accelerations, the clutch automatically disengages.
TOW/HAUL Switch

STARTING AND OPERATING 149
NOTE:
•The torque converter clutch will not engage (and 68RFE-
equipped trucks will not shift to sixth gear), until the
transmission fluid and engine coolant are warm [usually
after 1 to 3 miles (2 to 5 km) of driving]. Because the
engine speed is higher when the torque converter clutch
is not engaged, it may seem as if the transmission is not
shifting properly when cold. This is normal. Using the
Electronic Range Select (ERS) shift control, when the
transmission is sufficiently warm, will demonstrate that
the transmission is able to shift into and out of Over-
drive.
• If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the transmis-
sion 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 converter
will refill within five seconds after starting the engine.MANUAL TRANSMISSION — IF EQUIPPED
WARNING!
You or others could be injured if you leave the vehicle
unattended without having the parking brake fully
applied. The parking brake should always 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 attempt to hold the vehicle on a hill with the clutch
pedal partially engaged, as this will cause abnormal
wear on the clutch.
NOTE: During cold weather, you may experience in-
creased effort in shifting until the transmission fluid warms
up. This is normal.

Downshifting
Moving from a high gear down to a lower gear is recom-
mended to preserve brakes when driving down steep hills.
In addition, downshifting at the right time provides better
acceleration when you desire to resume speed. Downshift
progressively. Do not skip gears to avoid overspeeding the
engine and clutch.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid.
CAUTION!
When descending a hill, be very careful to downshift
one gear at a time to prevent overspeeding the engine
which can cause valve damage, and/or clutch disc
damage even if the clutch pedal is pressed.
Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the recommended downshifting
speeds may cause the engine to overspeed and/or
damage the clutch disc even if the clutch pedal is

CAUTION!
If you skip a gear while downshifting or downshift at
too high of a vehicle speed, these conditions may cause
the engine to overspeed if too low of a gear is selected
and the clutch pedal is released. Damage to the clutch
and the transmission can result from skipping a gear
while downshifting or downshifting at too high of a
vehicle speed even if the clutch pedal is held pressed
(i.e., not released).
Reverse Shifting
To shift into REVERSE (R), bring the vehicle to a complete
stop. Press the clutch and pause briefly to allow the gear
train to stop rotating. Beginning from the NEUTRAL (N)
position, move the gear selector in one quick smooth
motion straight across and into the REVERSE (R) area (the
driver will feel a firm “click” as the shifter passes the
“knock-over”). Complete the shift by pulling the gear
selector into REVERSE (R). The “knock-over” prevents the driver from accidentally
entering the REVERSE (R) shift area and warns the driver
that they are about to shift the transmission into REVERSE
(R). Due to this feature, a slow shift to REVERSE (R) can be
perceived as a high shift effort.
To shift out of REVERSE bring the vehicle to a complete
stop and press the clutch. Shifting out of REVERSE prior to
a complete stop may cause high shift effort.
AUXILIARY SWITCHES — IF EQUIPPED
There can be up to five auxiliary switches located in the
lower switch bank of the instrument panel which can be
used to power various electronic devices and PTO (Power
Take Off) – If Equipped. If Power Take Off is equipped, it
will take the place of the fifth Auxiliary switch. Connec-
tions to the switches are found under the hood in the
connectors attached to the auxiliary Power Distribution
Center.

STARTING AND OPERATING 153
You have the ability to configure the functionality of the
auxiliary switches via the instrument cluster display. All
switches can now be configured for setting the switch type
operation to latching or momentary, power source of either
battery or ignition, and ability to hold last state across key
cycles.
NOTE:Holding last state conditions are met when switch
type is set to latching and power source is set to ignition.
For further information on using the auxiliary switches,
please refer to the Ram Body Builders Guide by accessing
www.rambodybuilder.comand choosing the appropriate
links.
POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with PTO Prep and either the
AS69RC automatic six-speed or G-56 manual six-speed
transmissions, will allow for an aftermarket upfit with a
transmission driven PTO (power take off). The customer
will have the ability to operate the PTO in either a
“stationary” or “mobile” mode. The vehicles will be factory
set to the “stationary” mode. To select ’mobile mode’ You
will need to enter the commercial vehicle menu on the
instrument cluster display and select mobile PTO mode. Details of the PTO selection modes and further PTO
information is available at the Ram Truck Bodybuilders
web site.
rambodybuilder.com
AS69RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS69RC) operates at torque
converter turbine speed. The turbine speed will be less
than engine speed when the torque converter clutch is not
engaged and will be same as engine speed when the torque
converter clutch is engaged.
Stationary Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
•
Transmission in PARK position (vehicles equipped with
automatic transmission.)
• PTO switch has been activated.
• Parking brake applied (vehicles equipped with manual
transmission).
• Brake pedal must not be applied.
• Vehicle engine must be running.
• No vehicle, brake or clutch switch faults present.
154 STARTING AND OPERATING
•PTO must be correctly installed using the vehicle pro-
vided circuits.
The instrument cluster will display a PTO Onmessage for
five seconds if the above conditions are met. Otherwise, the
instrument cluster will display a message To Operate PTO
Shift To Park indicating what operator action should be
taken to engage the PTO mode.
The customer has the choice to operate the PTO by utilizing
the cruise control switches or by utilizing a remote control
(provided by the PTO supplier). To operate the feature
using the cruise control switches, the customer must first
activate the PTO switch which will turn on the PTO. In
order to increase or decrease the engine idle speed, to
optimize the PTO function, the “RESUME/ACCEL” and
“DECEL” cruise switches can be used respectively. To
disengage PTO operation and return to “standard vehicle
operation” simply toggle the PTO switch to the OFF
position.
The torque converter clutch (TCC) will automatically en-
gage at engine speeds above 1,200 RPM (engine speed) in
PTO stationary mode. Once engaged, the TCC will remain
applied and will not disengage until the engine speed falls
below 1,000 RPM. TCC engagement is desirable for certain
types of PTO applications (Automatic Transmission Only). To operate the PTO via a remote switch, the customer must
make sure the above conditions are met. It is vital for
proper operation that the PTO and remote have been
installed correctly, paying special attention to ensure the
vehicle provided wiring has been connected properly. This
is the responsibility of the installer of the PTO and
switches/remote system. It is the responsibility of the PTO
manufacturer to ensure that their electrical (switches and
remote) system is compatible with the vehicle’s electrical
architecture and software functionality.
NOTE:
Single set speed can be programmed via the PTO
menu on the instrument cluster display. Further details are
available at the Ram Truck Bodybuilders web site located
at
rambodybuilder.com
Mobile Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Mobile mode is activated via the menu on the instru-
ment cluster display.
• (ON/OFF) switch has been activated.
• Vehicles with automatic transmission must be in PARK
or DRIVE.
