Message Process Flow (Catalyst Full Message)
(Diesel Engines Only)
Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards for 2007 MY
(HDDE07), resulting in the lowest emitting diesel engine
ever produced. To achieve these emission standards your Dodge Chassis
Cab truck is equipped with state of the art engine and
exhaust system. The engine and exhaust aftertreatment
system work together to achieve the HDDE07 standard.
These systems are seamlessly integrated into your Dodge
truck and managed by the Cummins 6.7L engine Power-
train Control Module (PCM). The PCM manages engine
combustion to allow the exhaust system’s catalyst to trap
and burn Particulate Matter (PM) pollutants, with no
input or interaction on your part.
Additionally, the overhead console in your Dodge truck
has the ability to alert you to additional maintenance
required on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC): MAINTAINING YOUR VEHICLE 415

reference holes when the transmission reaches 180° F (21°
C). Remember it is best to check the level at the normal
operating temperature.
CAUTION!Be aware that if the fluid temperature is below 50° F
(10° C), it may not register on the dipstick. Do not
add fluid until the temperature is elevated enough to
produce an accurate reading.
7. Check for leaks. Release the Parking Brake.
NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated positions, as long as its seal remains
engaged in the dipstick tube. Automatic Transmission Fluid and Filter Change
The fluid and filter(s) should be changed and the as
specified in the Maintenance Schedule (Section 8). Ve-
hicles having severe usage should follow Maintenance
Schedule “B” of the Maintenance Schedule (Section 8).
Severe usage consists of:
• Off-the-highway operation;
• Trailer towing;
• Snow plow operation;
• Prolonged operation with heavy loading, especially in
hot weather.
NOTE: If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted (if equipped).440 MAINTAINING YOUR VEHICLE

The fluid and filter(s) should be changed and the bands
adjusted (if equipped) as specified in the Maintenance
Schedule (Section 8). Vehicles equipped with gas engines
having severe usage should follow Maintenance Sched-
ule “B” of the Maintenance Schedule (Section 8).
Severe usage consists of:
• Off-the-highway operation;
• Trailer towing;
• Snow plow operation;
• Prolonged operation with heavy loading, especially in
hot weather.
NOTE: If the transmission is disassembled for any
reason, the fluid and filter should be changed, and the
bands adjusted (if equipped). Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front and rear Wheel Bearings
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
“purge” excess grease and the bearing will look slightly
wet. This is normal. Periodic inspection for excess play is
recommended.444 MAINTAINING YOUR VEHICLE
