automatic transmission Ram 1500 2020 Owner's Guide

514 SERVICING AND MAINTENANCE
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.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis -
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools. If you notice fluid leakage or transmission malfunction, visit
an authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at the
factory will provide satisfactory lubrication for the life of the
vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contaminated
(with water, etc.), or if the transmission is disassembled for
any reason.
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.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to adjust
the fluid level accurately.
