2019 Ram 3500 automatic transmission

522 SERVICING AND MAINTENANCE
(Continued)
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is ingear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the vehicle.
• Do not idle the engine with any ignition components disconnected or removed, such as when diagnostic testing,
or for prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be drained, flushed and
refilled with fresh coolant. Check the front of the A/C
condenser (if equipped) or radiator for any accumulation of
bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the A/C
condenser (if equipped) or the back of the radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the radiator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.
• When working near the radiator cooling fan, discon -
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can start at
any time the ignition is in the ON mode.

528 SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to ensure
optimum transmission performance and life. Use only the
manufacturer’s specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It is
important to maintain the transmission fluid at the correct
level using the recommended fluid. No chemical flushes
should be used in any transmission; only the approved lubri-
cant should be used. Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis
-
sion Fluid (ATF) is an engineered product and its perfor -
mance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the transmis -
sion. Avoid using transmission sealers as they may
adversely affect seals.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate the brake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
WARNING! (Continued)CAUTION!
Using a transmission fluid other than the manufacturer’s
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids, Lubricants, And Genuine
Parts” in this section for fluid specifications.
CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.
