2023 JEEP GLADIATOR transmission fluid

SERVICING AND MAINTENANCE381
TRANSFER CASE
Fluid Level Check
The fluid level should be to the bottom edge of the
fill hole when the vehicle is in a level position.

Transfer Case

Drain And Refill
For the proper maintenance intervals Úpage 354.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid
Úpage 426.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug. The
fluid level should be between the bottom of the fill
hole and a point not more than 3/16 of an inch
(4.76 mm) below the bottom of the hole.
Add fluid, if necessary, to maintain the proper
level.
Frequency Of Fluid Change
Under normal operating conditions, the fluid
installed at the factory will give satisfactory
lubrication for the life of the vehicle. If the fluid
becomes contaminated with water, it should be
changed immediately. Otherwise, change the fluid
as recommended in the Maintenance Plan
Úpage 354.
Selection Of Lubricant
Use only manufacturer's recommended manual
transmission fluid Ú page 424.
AUTOMATIC TRANSMISSION —

Special Additives
It is strongly recommended against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product
and its performance may be impaired by
supplemental additives. Therefore, do not add any
fluid additives to the transmission. Avoid using
transmission sealers as they may adversely affect
seals.

CAUTION!
Do not use chemical flushes in your transmis -
sion as the chemicals can damage your trans -
mission components. Such damage is not
covered by the New Vehicle Limited Warranty.

382SERVICING AND MAINTENANCE
(Continued)
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 transmission 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.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only manufacturer's specified
transmission fluid Ú
page 426. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.

General Information
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe transmis -
sion damage may occur. An authorized dealer
has the proper tools to adjust the fluid level
accurately.
CAUTION!
Using a transmission fluid other than
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 426.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. Failure to use proper fuses may result in
serious personal injury, fire and/or property
damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
