Automatic Transmission - If Equipped - Jeep 2013 Wrangler Owner's Manual

WARNING! (Continued)
• To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser-
voir cap secured at all times. Brake fluid in
a 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 accident.
• 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 an accident.

Automatic Transmission – If
Equipped
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission perfor-
mance and life. Use only the manufacturer's
recommended transmission fluid. Refer to "Flu-
ids, Lubricants, and Genuine Parts" in "Main-
taining Your Vehicle" for fluid specifications. 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.
CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder, and
will require more frequent fluid and filter
changes. Refer to "Fluids, Lubricants, and
Genuine Parts" in "Maintaining Your Vehicle"
for fluid specifications.
Special Additives
The manufacturer strongly recommends
against using any special additives in the trans-
mission.
Automatic Transmission Fluid (ATF) is an engi-
neered product and its performance may be
impaired by supplemental additives. Therefore,
do not add any fluid additives to the transmis-
sion. The only exception to this policy is the use
of special dyes for diagnosing fluid leaks. Avoid
using transmission sealers as they may ad-
versely affect seals.
