AUTOMATIC TRANSMISSION
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life.
Use the manufacturer specified transmission fluid
page 265. It is important to maintain the transmis-
sion fluid at the correct level using the recommended
fluid.
NOTE:
No chemical flushes should be used in any transmis-
sion; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder
page 265.
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 addi-
tives. Therefore, 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 in 9-speed
transmissions. 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
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 filler tube is capped and no dipstick is
provided. An authorized dealer can check your trans-
mission fluid level using a special service dipstick. 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 transmis-
sion damage.
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.
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. How-
ever, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
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
1 — Fuse Element
2 — Blade Fuse with a good/functional fuse element
3 — Blade Fuse with a bad/not functional fuse element
(blown fuse)
