automatic transmission Ram 1500 2013 Service Manual

When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in first gear (using the ERS switches) can help to
avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified forpolice, taxi,
fleet, or frequent trailer towing.. Refer to “Maintenance
Schedule” for the proper maintenance intervals.
NOTE: Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, turn the “TOW/HAUL” feature ON when driving in
hilly areas, or select a lower gear range (using the
Electronic Range Select (ERS) switches) on more severe
grades.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
556 STARTING AND OPERATING

Maintain and operate your vehicle and snowplow equip-
ment following the recommendations provided by the
specific snowplow manufacturer.
Over The Road Operation With Snowplow
Attached
The blade restricts air flow to the radiator and causes the
engine to operate at higher than normal temperatures.
Therefore, when transporting the plow, angle the blade
completely and position it as low as road or surface
conditions permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping distance
and allow adequate passing clearance.
Operating Tips
Under ideal snow plowing conditions, 20 mph (32 km/h)
should be maximum operating speed. The operator
should be familiar with the area and surface to be
cleaned. Reduce speed and use extreme caution when
plowing unfamiliar areas or under poor visibility.
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 drivetrain
damage, the following precautions should be observed.
•Operate 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.
• Vehicles with automatic transmissions should use 4L
range when plowing deep or heavy snow for extended
periods of time to avoid transmission overheating.
• Do not shift the transmission unless the engine has
returned to idle and wheels have stopped. Make a
practice of stepping on the brake pedal while shifting
the transmission.

STARTING AND OPERATING 561

NOTE:Vehicles equipped with air suspension must be
lowered to the “Entry/Exit” (lowest) level, and have
automatic leveling disabled, before tying them down
(from the body) on a trailer or flatbed truck. Refer to “Air
Suspension – If Equipped” for more information. If the
vehicle cannot be lowered to the “Entry/Exit” level (for
example, engine will not run), tie-downs must be fas-
tened to the axles (not to the body). Failure to follow
these instructions may cause fault codes to be set and/or
cause loss of proper tie-down tension.
Recreational Towing – Two-Wheel Drive Models
DO NOT flat tow this vehicle. Damage to the drivetrain
will result.
Recreational towing (for two-wheel drive models) is
allowed ONLYif the rear wheels are OFFthe ground.
This may be accomplished using a tow dolly or vehicle
trailer. If using a tow dolly, follow this procedure: 1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Place automatic trans- mission in PARK, manual transmission in gear (not in
NEUTRAL).
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s instructions.
5. Remove the key fob from the ignition switch.
6. Install a suitable clamping device, designed for tow- ing, to secure the front wheels in the straight position.
562 STARTING AND OPERATING

CAUTION!
•Towing with the rear wheels on the ground will
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
• Do not disconnect the driveshaft because fluid may
leak from the transmission, causing damage to
internal parts.
Recreational Towing – Four-Wheel Drive Models
NOTE: Both the manual shift and electronic shift trans-
fer cases must be shifted into NEUTRAL (N) for recre-
ational towing. Automatic transmissions must be shifted
into PARK for recreational towing. Manual transmissions
must be placed in gear (NOT in NEUTRAL) for recre-
ational towing. Refer to the following for the proper
transfer case NEUTRAL (N) shifting procedure for your
vehicle.
CAUTION!
• Front or rear wheel lifts must not be used. Internal
damage to the transmission or transfer case will
occur if a front or rear wheel lift is used when
recreational towing.
