VERIFICATION TESTS

CONTAINER IDENTIFICATION
Standard engine oil identification notations have
been adopted to aid in the proper selection of engine
oil. The identifying notations are located on the label
of engine oil plastic bottles and the top of engine oil
cans (Fig. 5).
This symbol on the front of an oil container means
that the oil has been certified by the American Petro-
leum Institute (API) to meet all the lubrication
requirements specified by DaimlerChrysler.
FLEXIBLE FUEL ENGINE OIL - 3.3L
Engine Oil Selection for Operating on E-85 Fuel
If vehicle operates on E-85 fuel either full or part-
time, use only MopartFlexible Fuel 5W-30 engine oil
or an equivalent that meets DaimlerChrysler Stan-
dard MS-9214. Equivalent commercial Flexible Fuel
engine oils may be labeled as Multi-Fuel, Variable
Fuel, Flexible Fuel, etc. These engine oils may be
satisfactory if they meet the DaimlerChrysler Stan-
dard.
SAE 5W-30 engine oil is preferred for use in Flex-
ible Fuel engines.
CAUTION: If Flexible Fuel engine oil is not used
when using E-85 fuel, engine wear or damage may
result.
DESCRIPTION - AUTOMATIC TRANSMISSION
FLUID
NOTE: Refer to the maintenance schedules for the
recommended maintenance (fluid/filter change)
intervals for this transaxle.
NOTE: For fluid level checking procedures, (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC -
31TH/FLUID - STANDARD PROCEDURE) (Refer to 21
- TRANSMISSION/TRANSAXLE/AUTOMATIC - 41TE/
FLUID - STANDARD PROCEDURE)NOTE: The 41TE transaxle has a common transmis-
sion and differential sump. Filling the transaxle
accommodates the differential as well.
TRANSMISSION FLUID
MopartATF+4 (Automatic Transmission Fluid-
Type 9602) is required in this transaxle. Substitute
fluids can induce torque converter clutch shudder.
MopartATF+4 (Automatic Transmission Fluid-
Type 9602) when new is red in color. The ATF is dyed
red so it can be identified from other fluids used in
the vehicle such as engine oil or antifreeze. The red
color is not permanent and is not an indicator of fluid
condition. As the vehicle is driven, the ATF will begin
to look darker in color and may eventually become
brown.This is normal.A dark brown/black fluid
accompanied with a burnt odor and/or deterioration
in shift quality may indicate fluid deterioration or
transmission component failure.
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the
addition of any fluids to the transmission, other than
those automatic transmission fluids listed above.
Exceptions to this policy are the use of special dyes
to aid in detecting fluid leaks.
Various ªspecialº additives and supplements exist
that claim to improve shift feel and/or quality. These
additives and others also claim to improve converter
clutch operation and inhibit overheating, oxidation,
varnish, and sludge. These claims have not been sup-
ported to the satisfaction of DaimlerChrysler and
these additivesmust not be used.The use of trans-
mission ªsealersº should also be avoided, since they
may adversely affect the integrity of transmission
seals.
DESCRIPTION - FUEL REQUIREMENTS
Your engine is designed to meet all emissions reg-
ulations and provide excellent fuel economy and per-
formance when using high quality unleaded gasoline
having an octane rating of 87. The use of premium
gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality reg-
ular gasoline, and in some circumstances may result
in poorer performance.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued heavy
spark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
