transmission DODGE RAM 3500 DIESEL 2008 3.G Workshop Manual

NOTE:During snowplow usage on vehicles equipped
with an overhead console module, the outside tempera-
ture display will show higher temperatures than the
outside ambient temperature. The higher displayed tem-
perature is due to blocked or reduced airflow to the
underhood ambient temperature sensor by the snow-
plow. This is common and outside temperature display
operation will return to normal when the snowplow is
removed.
General Maintenance
Snowplows should be maintained in accordance with the
plow manufacturer's instructions.
Keep all snowplow electrical connections and battery
terminals clean and free of corrosion.When plowing snow, to avoid transmission and driv-
etrain damage, the following precautions should be ob-
served.
²Operate with transfer case in 4L when plowing small
or congested areas where speeds are not likely to
exceed 15 mph (24 km/h). At higher speeds operate in
4H.
²Vehicles with 68RFE transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
²Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal before shifting
the transmission.

Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service center
where it can be raised on a lift.Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the ª4Lº position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
