2012 Ram 5500 Chassis Cab transmission

Reverse Shifting
To shift into REVERSE (R), bring the vehicle to a com-
plete stop. Press the clutch and pause briefly to allow the
gear train to stop rotating. Beginning from the NEUTRAL
(N) position, move the shift lever 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 shift
lever 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 RE-
VERSE (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.
POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with either the AS68RC
automatic six-speed or G-56 manual six-speed transmis-
sions, will allow for an aftermarket upfit with a transmis-
sion 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. In order to select the “mobile” mode
an authorized dealership is required to modify the vehi-
cle’s settings using their proprietary authorized dealer
service tool.
AS68RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS68RC) 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.
78 STARTING AND OPERATING

Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Be in PARK position (vehicles equipped with auto-
matic transmission)
•Upfitter provider (on/off) 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
•PTO must be correctly installed using the vehicle
provided circuits
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 oper-
ate the feature using the cruise control switches, the
customer must first activate the upfitter-provided on/off
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 turn the upfitter-provided on/off switch to the
OFF position.
The torque converter lockup clutch will automatically
engage at engine speeds above 1,200 RPM (engine speed)
in PTO stationary mode. Once engaged, the lockup clutch
will remain on and not disengage until the engine speed
is below 1,000 RPM. Lockup clutch engagement is desir-
able for certain types of PTO applications (AS68RC
Six-Speed Automatic Transmission Only).

STARTING AND OPERATING 79

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:If you desire a single PTO speed, your vehicle
must be wired to use a remote PTO switch. For instruc-
tions on programming the SET speed, refer to the
LEARNING SET SPEED section of the Body Builder’s
Guide which can be found at www.ramtrucks.com.
Mobile Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Authorized dealer-selected “mobile” mode activated
via authorized dealer proprietary service tool
•Upfitter-provided (on/off) switch has been activated
•Vehicle must be in PARK or DRIVE position (vehicles
equipped with automatic transmission)
•Parking brake must not be applied
•Brake pedal must not be applied
•No vehicle, brake or clutch switch faults present
•Vehicle engine must be running
•PTO must be correctly installed using the vehicle
provided circuits
The customer may choose to use the PTO while the
vehicle is moving. To do so, the PTO function must be
activated prior to taking the vehicle out of PARK. This is
accomplished by activating the upfitter-provided PTO
80 STARTING AND OPERATING

JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connect-
ing jumper cables or allow cable clamps to touch
each other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
•Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e.,
do not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.

•Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized Chrysler Group LLC
dealership or qualified repair center.
(Continued)
CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended maintenance
intervals. Do not use chemical flushes in these
components as the chemicals can damage your
engine, transmission, power steering or air condi-
tioning. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check
the oil level is before starting the engine after it has been
100 MAINTAINING YOUR VEHICLE

Fluid Level Check
This fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.
Manual Transmission – If Equipped
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
The fluid level can be checked by removing the filler
plug. If the level of the lubricant is more than 1/2 in
(12 mm) below the bottom of the filler hole while the
vehicle is on level ground, enough lubricant should be
added to bring the level to 1/4 in (6 mm) below the
bottom of the filler hole.
Automatic Transmission – If Equipped
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check – Ram Truck Only
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. At normal operating tem-
perature, the fluid cannot be held comfortably between
the fingertips. Operation of the transmission with an
improper fluid level will greatly reduce the life of the
transmission and of the fluid. Check the fluid level
whenever the vehicle is serviced.
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
