2023 JEEP WAGONEER transmission

326SERVICING AND MAINTENANCE
To minimize the possibility of catalytic converter damage:
Do not interrupt the ignition when the transmission is
in gear 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 is dirty, the system
should be drained, flushed, and refilled with fresh Organic
Additive Technology (OAT) coolant (conforming to
MS.90032) by an authorized dealer. Check the front of the
A/C condenser for any accumulation of bugs, leaves, etc.
If dirty, clean by gently spraying water from a garden hose
vertically down the face of the condenser.
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.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead
to severe internal engine damage. If any coolant is needed
to be added to the system please contact an authorized
dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
Organic Additive Technology (OAT) coolant (conforming to
MS.90032).
For the proper maintenance intervals
Úpage 310.
Selection Of Coolant
Refer to Engine Fluids And Lubricants Úpage 376.
NOTE:
Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant,
may result in engine damage and may decrease corro -
sion protection. OAT engine coolant is different and
should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant or any “globally compat -
ible” coolant. If a non-OAT engine coolant is introduced
into the cooling system in an emergency, the cooling
system will need to be drained, flushed, and refilled
with fresh OAT coolant (conforming to MS.90032), by
an authorized dealer as soon as possible.
 Do not use water alone or alcohol-based engine
coolant products. Do not use additional rust inhibitors
or antirust products, as they may not be compatible
with the radiator engine coolant and may plug the radi -
ator.
 This vehicle has not been designed for use with
propylene glycol-based engine coolant. Use of
propylene glycol-based engine coolant is not recom -
mended.
 Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system please contact an
authorized dealer.
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
position. The fan is temperature controlled and can
start at any time the ignition is in the ON position.

SERVICING AND MAINTENANCE329
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends 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.
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 the manufacturer's specified transmission fluid
Úpage 377. 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 transmission;
only the approved lubricant should be used.

To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in an open container absorbs moisture from the
air resulting in a lower boiling point. This may cause
it to boil unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This could
result in a collision.
 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!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.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or torque
converter shudder.8

FUSES
General Information
The fuses protect electrical systems against excessive
current.
When a device does not work, you must check the fuse
element inside the blade fuse for a break/melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may result in
vehicle battery discharge.

Blade Fuses

Underhood Fuses
The Power Distribution Center (PDC) is located on the
passenger side of the engine compartment, behind the
headlamp. This center contains cartridge fuses, micro
fuses, relays, and circuit breakers. A description of each
fuse and component may be stamped on the inside cover,
otherwise the cavity number of each fuse is stamped on
the inside cover that corresponds to the following chart.
WARNING!
When replacing a blown fuse, always use an appro -
priate 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 indicated 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 material. Do not place
a fuse inside a circuit breaker cavity or vice versa.
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 autho -
rized dealer.
 If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse element
3 — Blade fuse with a bad/not functional fuse element
(blown fuse)
CAUTION!
When installing the Power Distribution Center cover, it is
important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to get
into the Power Distribution Center and possibly result in
an electrical system failure.
