2017 JEEP WRANGLER check transmission fluid

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustration.
Towing Tips
Before setting out on a trip, practice turning, stopping and
backing the trailer in an area away from heavy traffic.If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.
If you REGULARLY tow a trailer for more than 45 minutes
of continuous operation, then change the transmission
fluid and filter as specified for police, taxi, fleet, or frequent
trailer towing. Refer to the “Maintenance Plan” for the
proper maintenance intervals.
NOTE: Check the automatic transmission fluid level before
towing.

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 (Low) 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.
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 components, and your brakes will be less
effective once wet and/or muddy.
• This vehicle is capable of crossing through water at a
depth of 30 inches (76 cm) at speeds no greater than
5 mph (8 km/h). Water ingestion can occur causing
damage to your vehicle.
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

372 SERVICING AND MAINTENANCE

Transfer Case
Fluid Level Check
The fluid level should be to the bottom edge of the fill hole
(A) when the vehicle is in a level position.
Adding Fluid
Add fluid at the filler hole, until it runs out of the hole,
when the vehicle is in a level position.
Drain
First remove the fill plug (B), then the drain plug (C). The
recommended tightening torque for the drain and fill plugs
is 15 to 25 ft lbs (20 to 34 N·m).
CAUTION!
When replacing the plugs, do not overtighten them.
You could damage them and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
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”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.Transfer Case
402 SERVICING AND MAINTENANCE

NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
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. There-
fore, do not add any fluid additives to the transmission.
The only exception to this policy is the use of special dyes
for diagnosing fluid leaks. Avoid using transmission seal-
ers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
It is best to check the fluid level when the transmission is
at normal operating temperature (approximately 180°F/
82°C). This occurs after at least 15 miles (25 km) of driving.
At normal operating temperature, the fluid cannot be held
comfortably between the fingertips.
Use the following procedure to check the transmission
fluid level properly:
1. Park the vehicle on level ground.
2. Remove the engine cover by pulling it up off the mounting studs (two in the front and two in the rear).
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake, and press the brake pedal.

5. Place the gear selector momentarily into each gearposition (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole. The fluid level
should be between the HOT (upper) reference holes on
the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube to
bring it to the proper level. Do not overfill.Use ONLY
the specified fluid (refer to Fluids And Lubricants
under “Technical Specifications” for fluid specifica-
tions). After adding any quantity of oil through the
dipstick tube, wait a minimum of two minutes for the oil
to fully drain into the transmission before rechecking
the fluid level. NOTE:
•The holes in the dipstick will be full of fluid if the
actual level is at or above the hole.
• If it is necessary to check the transmission below the
operating temperature, the fluid level should be be-
tween the two COLD (lower) holes on the dipstick
with the fluid at approximately 80°F (27°C). If the fluid
level is correctly established at 80° F (27°C), it should
be between the HOT (upper) reference holes when the
transmission reaches 180° F (82°C). Remember it is best
to check the level at the normal operating temperature.
CAUTION!
If the fluid temperature is below 50°F (10°C) it may not
register on the dipstick. Do not add fluid until the
temperature is elevated enough to produce an accurate
reading. Run the engine at idle, in PARK, to warm the
fluid.
8. Reinstall the engine cover and snap it down securely onto the four mounting studs.
9. Check for leaks. Release the parking brake.
404 SERVICING AND MAINTENANCE

NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is normal
for the dipstick cap to spring back slightly from its fully
seated position, as long as its seal remains engaged in the
dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
In addition, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Manual Transmission — If Equipped
Selection Of Lubricant
Use only manufacturer’s recommended manual transmis-
sion fluid. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
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. Refer to
the “Maintenance Plan” for the proper maintenance inter-
vals.
RAISING THE VEHICLE
In the case where it is necessary to raise the vehicle, go to
an authorized dealer or service station.
