2016 JEEP WRANGLER 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 supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes for diagnosing fluid
leaks. Avoid using transmission sealers 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 themounting studs (two in the front and two in the rear).
3. Run the engine at idle speed and normal operating temperature.
4. Fully apply the parking brake, and press the brake pedal.

5. Place the shift lever momentarily into each gear posi-tion (allowing time for the transmission to fully en-
gage 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, Lubricants, And Genuine Parts for
fluid specifications). 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
between 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). Re-
member it is best to check the level at the normal
operating temperature.
634 MAINTAINING YOUR VEHICLE

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.
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 Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
Clutch Hydraulic System (Manual Transmission)
— If Equipped
The clutch hydraulic system is fed by a segregated
volume of fluid within the brake system master cylinder
reservoir. In the event of leakage or wear, use only the
manufacturer’s recommended brake fluid. Refer to “Flu-
ids, Lubricants, And Genuine Parts” in “Maintaining
Your Vehicle” for further information.

Manual Transmission — If Equipped
Selection Of Lubricant
Use only manufacturer’s recommended manual trans-
mission fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
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 in (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
Schedule. Refer to the “Maintenance Schedule” for the
proper maintenance intervals.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days, you may want to take steps to protect your battery.
You may:
•Remove Cartridge fuse #J13 in the Power Distribution
Center (PDC) labeled Ignition-Off Draw (IOD) and
store it in a safe location within the PDC. •
Or, disconnect the negative cable from the battery.
• Anytime you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
