2023 JEEP GLADIATOR automatic transmission fluid

STARTING AND OPERATING165
completed, place the automatic transmission into
DRIVE or release the clutch pedal on a manual
transmission.
NOTE:Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty may occur
due to the mating teeth not being properly aligned.
Several attempts may be required for clutch teeth
alignment and shift completion to occur. The
preferred method is with the vehicle rolling at 1 to
3 mph (2 to 5 km/h). Avoid attempting to engage
or disengage 4L with the vehicle moving faster
than 1 to 3 mph (2 to 5 km/h).
During cold weather, you may experience
increased effort in shifting until the transfer case
fluid warms up. This is normal.
TRAC-LOK REAR AXLE — IF EQUIPPED
The Trac-Lok rear axle provides a constant driving
force to both rear wheels and reduces wheel spin
caused by the loss of traction at one driving wheel.
If traction differs between the two rear wheels, the
differential automatically proportions the usable
torque by providing more torque to the wheel that
has traction.
Trac-Lok is especially helpful during slippery
driving conditions. With both rear wheels on a
slippery surface, a slight application of the
accelerator will supply maximum traction.
AXLE LOCK (TRU-LOK) FRONT AND
R
EAR — IF EQUIPPED
The AXLE LOCK switch is located on the instrument
panel (to the right of the steering column).

Axle Lock Switch Panel

This feature will only activate when the following
conditions are met:
Ignition in ON/RUN position, vehicle in 4L
(Four-Wheel Drive Low Range).
Vehicle speed should be 10 mph (16 km/h) or
less.
Both right and left wheels on axle are at the
same speed.
WARNING!
Failure to engage a transfer case position
completely can cause transfer case damage or
loss of power and vehicle control. You could have
a collision. Do not drive the vehicle unless the
transfer case is fully engaged.
WARNING!
On vehicles equipped with a limited-slip
differential, never run the engine with one rear
wheel off the ground. The vehicle may drive
through the rear wheel remaining on the ground
and cause you to lose control of your vehicle.

212STARTING AND OPERATING
IF YOU STALL OR BEGIN TO LOSE HEADWAY
If you stall or begin to lose headway while climbing
a steep hill, allow your vehicle to come to a stop
and immediately apply the brake. Restart the
engine and shift into REVERSE. Back slowly down
the hill allowing engine braking to control the
descent and apply your brakes, if necessary, but
do not allow the tires to lock.
Driving Through Water
Extreme care should be taken crossing any type of
water. Water crossings should be avoided, if
possible, and only be attempted when necessary in
a safe, responsible manner. You should only drive
through areas which are designated and approved.
You should tread lightly and avoid damage to the
environment. You should know your vehicle's
abilities and be able to recover it if something goes wrong. You should never stop or shut a vehicle off
when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls,
do not attempt to restart it. Determine if it has
ingested water first. The key to any crossing is low
and slow. Shift into FIRST gear (manual
transmission), or DRIVE (automatic transmission),
with the transfer case in the 4L position and
proceed very slowly with a constant slow speed
(3 to 5 mph {5 to 8 km/h} maximum) and light
throttle. Keep the vehicle moving; do not try to
accelerate through the crossing. After crossing any
water higher than the bottom of the axle
differentials, you should inspect all of the vehicle
fluids for signs of water ingestion.
BEFORE YOU CROSS ANY TYPE OF WATER
As you approach any type of water, you need to
determine if you can cross it safely and
responsibly. If necessary, get out and walk through
the water or probe it with a stick. You need to be
sure of its depth, approach angle, current and
bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure you
will not be intruding on any wildlife, and you can
recover the vehicle if necessary. The key to a safe
crossing is the water depth, current and bottom
conditions. On soft bottoms, the vehicle will sink in,
effectively increasing the water level on the
vehicle. Be sure to consider this when determining
the depth and the ability to safely cross.
CROSSING PUDDLES, POOLS, FLOODED
AREAS OR OTHER STANDING WATER
Puddles, pools, flooded or other standing water
areas normally contain murky or muddy waters.
These water types normally contain hidden
obstacles and make it difficult to determine an
accurate water depth, approach angle, and bottom
condition. Murky or muddy water holes are where
you want to hook up tow straps prior to entering.
This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can
safely cross, than proceed using the low and slow
method.
WARNING!
If the engine stalls or you lose headway or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle, which
may result in severe injury. Always back carefully
straight down a hill in REVERSE. Never back
down a hill in NEUTRAL using only the vehicle
brakes. Never drive diagonally across a hill,
always drive straight up or down.
CAUTION!
Water ingestion into the axles, transmission,
transfer case, engine or vehicle interior can
occur if you drive too fast or through too deep
of water. Water can cause permanent damage
to engine, driveline or other vehicle compo -
nents, and your brakes will be less effective
once wet and/or muddy.
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage that may not be covered by the
New Vehicle Limited Warranty.

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 —

F EQUIPPED
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.
