² SG service engine oil is a high quality crankcase
lubricant designed for use in all naturally aspirated
engines. If SG service engine oil is used in turbo-
charged engine, change engine oil at every 4 800
km (3,000 miles) or three months.
² SG/CD service engine oil is a high quality crank-
case lubricant designed for use in most naturally as-
pirated and turbocharged gasoline or diesel engines.
FLEXIBLE FUEL VEHICLES
Vehicles operated using Flexible Fuel (M85) re-
quire engine oil that meet or exceed Chrysler Stan-
dard MS-9214. Mopar Flexible Fuel engine oil or
equivalent should be used when adding or changing
crankcase lubricant. The API symbol (Fig. 1) on the
container indicates the viscosity grade, quality and
fuel economy ratings of the lubricant it contains. Use
ENERGY CONSERVING II motor oil with API SER-
VICE SG or SG/CD classification.
ENGINE OIL ADDITIVES
Chrysler Corporation recommends that Mopar En-
gine Oil Supplement or equivalent be used when fric-
tion and corrosion reducing materials added to the
crankcase lubricant is desired.
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil,
oil foaming and oil pressure loss can result.
Inspect engine oil level approximately every 800
kilometers (500 miles). Position vehicle on level sur- face. With engine OFF, allow enough time for oil to
settle to bottom of crankcase, remove engine oil level
indicator (dipstick) and wipe clean. Install dipstick
and verify it is seated in the tube. Remove dipstick,
with handle above tip, take oil level reading (Fig. 2).
Add oil only if level is below MIN or ADD mark on
dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals
described in Lubrication and Maintenance Schedules.
Position the vehicle on a level surface. Hoist and
support vehicle on safety stands. Refer to Hoisting
and Jacking Recommendations in this group. Place a
suitable 3.8 liter (4 qt.) drain pan under crankcase
drain. Remove drain plug from crankcase. Inspect
drain plug threads for stretching or other damage.
Replace drain plug and gasket if damaged. Install
drain plug in crankcase. Lower vehicle and fill
crankcase with specified type and amount of engine
oil described in this section. Start engine and inspect
for leaks. Stop engine and inspect oil level.
ENGINE OIL FILTER
SELECTING OIL FILTER
Chrysler Corporation recommends a Mopar or
equivalent oil filter be used when replacement is re-
quired. A replacement filter must be designed to
withstand 1756 kPa (256 psi) of internal pressure.
OIL FILTER REPLACEMENT
Position a drain pan under the oil filter. Using a
suitable oil filter wrench (Fig. 3) loosen filter. When
filter separates from adapter nipple, tip gasket end
upward to minimize oil spill. Remove filter from ve-
hicle. With a wiping cloth, clean the gasket sealing
surface (Fig. 4) of oil and grime. Wipe off oil residue
from below oil filter adapter.
TO INSTALL NEW OIL FILTER: Lightly lubricate oil filter gasket with engine oil or
chassis grease. Thread filter onto adapter nipple.
When gasket makes contact with sealing surface,
tighten filter one full turn. If necessary use a filter
wrench, do not over tighten. Add oil, verify crank-
case oil level and start engine. Inspect for oil leaks.

PCV SYSTEM TEST
Refer to group 25, Emission Control System for
proper procedures to test PCV system.
FUEL RECOMMENDATIONS
Chrysler Corporation recommends that only fuel pur-
chased from a reputable retailer be used. Use high qual-
ity, unleaded gasoline to provide satisfactory
driveability and highest fuel economy. Gasoline contain-
ing detergent and corrosion control additives are desire-
able. If the engine develops spark knock (audible ping),
poor performance, hard starting or stalling, purchase
fuel from another source. Engine performance can vary
when using different brands of gasoline with the same
octane rating. Occasional light engine spark knock un-
der heavy acceleration, at low speed or when vehicle is
heavily loaded is not harmful. Extended periods of
spark knock under moderate acceleration or at cruising
speed can damage the engine. The cause of excessive
spark knock condition must be diagnosed and corrected.
For diagnostic procedures refer to Group 14, Fuel Sys-
tem and Powertrain Diagnostic Procedures manual.
SELECTING GASOLINE
CAUTION:Do not use fuel containing METHANOL
(methyl or wood alcohol), damage to fuel system
will result. Do not use leaded gasoline, damage to catalytic
converter will result and vehicle will not conform to
emission control standards.
ETHANOL, MTBE OR ETBE BLENDS
All Chrysler Corporation vehicles are designed to
use unleaded gasoline ONLY. Gasohol blends, con-
taining 10% Ethanol (ethyl or grain alcohol) 90% un-
leaded gasoline can be used provided it has adequate
octane rating. Fuel blends containing up to 15% MTBE (Methyl
Tertiary Butyl Ether) and 85% unleaded gasoline can
be used. Fuel blends containing up to 17% ETBE
(Ethyl Tertiary Butyl Ether) and 83% unleaded gas-
oline can also be used. Fuel blended with ethanol, MTBE or ETBE are
also referred to as reformulated or clean air gasoline.
These fuels contribute less emissions to the atmo-
sphere. Chrysler Corporation recommends that
blended fuels be used when available
METHANOL BLENDS Using gasoline blended with methanol can result
in starting and driveability problems. Deterioration
of fuel system components will result. Methanol in-
duced problems are not the responsibility of Chrysler
Corporation and may not be covered by the vehicle
warranty. NON-TURBOCHARGED ENGINES
Use regular unleaded gasoline having a minimum
octane rating of 87 (R+M)/2. Higher octane premium
unleaded gasoline can be used if desired.
2.2L 16 VALVE TURBOCHARGED ENGINE
Use premium unleaded gasoline having a mini-
mum octane rating of 91 (R+M)/2. Gasoline with oc-
tane rating less than 91 (R+M)/2 can be used if
recommended gasoline is not available. Low octane
gasoline will reduce engine performance.
FLEXIBLE FUEL VEHICLES
CAUTION: Do not use 100% methanol, damage to
fuel system can result. Use unleaded regular gasoline having a minimum
octane rating of 87 (R=M)/2 and M85 fuel that is
85% methanol and 15% unleaded gasoline, or a mix-
ture of these two.
FUEL FILTER
The fuel filter requires service only when a fuel
contamination problem is suspected. For proper diag-
nostic and service procedures refer to Group 14, Fuel
System,
IGNITION CABLES, DISTRIBUTOR CAP, AND
ROTOR
Inspect and test ignition cables, distributor cap and
rotor when the spark plugs are replaced. Oil and
grime should be cleaned from the ignition cables and
distributor cap to avoid possible spark plug fouling.
Mopar, Foamy Engine Degreaser, or equivalent is
recommended for cleaning the engine compartment.
For proper service and diagnostic procedures refer to
Group 8D, Ignition System.
SPARK PLUGS
Ignition spark plugs should be replaced at the
mileage interval described in the Lubrication and
Maintenance Schedules. Refer to the General Infor-
mation section of this group. For proper service pro-
cedures refer to Group 8D, Ignition Systems.
DRIVE BELTS
Inspect and adjust drive belts at the interval de-
scribed in the Lubrication and Maintenance Sched-
ules. Refer to General Information section of this
group. For proper inspection and adjustment proce-
dures, see Group 7, Cooling System.
EMISSION CONTROL SYSTEM
Inspect all emission control components and hoses
when other under hood service is performed. Refer to
emission system Vacuum Hose Label located on the

INSTALLATIONÐ3.3L AND 3.8L ENGINE
Place a new gasket (dipped in water) on the water
box surface, center thermostat into opening in the in-
take manifold. Place housing over gasket and ther-
mostat, making sure thermostat is in recess provided
(Fig. 13). Bolt housing to intake manifold, tighten
bolts to 28 N Im (250 in. lbs.). Refill cooling system
(see Refilling System ).
COOLANT
The cooling system is designed around the coolant.
The coolant must accept heat from engine metal, in
the cylinder head area near the exhaust valves. Then
carry this heat to the radiator where the tube/fin as-
semblies of these components can give it up to the
air.
PERFORMANCE
Performance is measurable. For heat transfer pure
water excels (Formul a = 1 btu per minute for each
degree of temperature rise for each pound of water).
This formula is altered when necessary additives to
control boiling, freezing, and corrosion are added as
follows:
² Pure Water (1 btu) boils at 100ÉC (212ÉF) and
freezes at 0ÉC (32ÉF).
² 100 Percent Glycol (.7 btu) can cause a hot engine
and detonation and will raise the freeze point to 22ÉC
(-8ÉF).
² 50/50 Glycol and Water (.82 btu) is the recom-
mended combination that provides a freeze point of
-37ÉC(-35ÉF).The radiator, water pump, engine water
jacket, radiator pressure cap, thermostat, tempera-
ture gauge, sending unit and heater are all designed
for 50/50 glycol. Where required, a 56 percent glycol and 44 percent
water mixture will provide a freeze point of-59ÉC
(-50ÉF).
CAUTION: Richer mixtures cannot be measured
with field equipment which can lead to problems
associated with 100 percent glycol.
SELECTION AND ADDITIVES
The use of aluminum cylinder heads, intake mani-
folds, and water pumps requires special corrosion
protection. Mopar Antifreeze, Prestone II, Peak or
antifreeze containing Alugard 340-2, or their equiva-
lent are recommended for best engine cooling with-
out corrosion. When mixed only to a freeze point of

GENERAL INFORMATION
Safety goggles should be worn at all times
when working on these transaxles. This transaxle combines a fully automatic 3 speed
transmission, final drive gearing, and differential into
a front wheel drive system. The unit is a Metric
design. The identification markings and usage of the
transaxle are charted in Diagnosis and Tests. Transaxle operation requirements are differ-
ent for each vehicle and engine combination and
some internal parts will be different to provide
for this. Therefore, when replacing parts, refer to
the seven digit part number stamped on rear of
the transaxle oil pan flange. Within this transaxle, there are 3 primary areas:
(1) Main center line plus valve body.
(2) Transfer shaft center line (includes governor and
parking sprag). (3) Differential center line. Center distances be-
tween the main rotating parts in these 3 areas are held
precise. This maintains a low noise level through
smooth accurate mesh of the gears. The torque converter, transaxle area, and differential
are housed in an integral aluminum die casting. The
differential oil sump is common with thetransaxle
sump. Separate filling of the differential is NOT nec-
essary. The torque converter is attached to the crankshaft
through a flexible driving plate. Cooling of the con-
verter is accomplished by circulating the transaxle
fluid through an oil-to-water type cooler located in the
radiator side tank and/or an oil-to air heat ex- changer. The torque converter assembly is a sealed
unit that cannot be disassembled.
The transaxle fluid is filtered by an internal filter
attached to the lower side of the valve body assem-
bly. Engine torque is transmitted to the torque con-
verter then, through the input shaft to multiple-disc
clutches in the transaxle. The power flow depends on
the application of the clutches and bands. Refer to
Elements in Use Chart in Diagnosis and Tests sec-
tion. The transaxle consists of two multiple-disc
clutches, an overrunning clutch, two servos, a hy-
draulic accumulator, two bands, and two planetary
gear sets. They provide three forward ratios and a re-
verse ratio. The common sun gear of the planetary
gear sets is connected to the front clutch by a driving
shell. The drive shell is splined to the sun gear and
to the front clutch retainer. The hydraulic system
consists of an oil pump, and a single valve body
which contains all of the valves except the governor
valves. The transaxle sump and differential sump are
both vented through the dipstick.Output torque
from the main center line is delivered through heli-
cal gears to the transfer shaft.This gear set is a
factor of the final drive (axle) ratio. The shaft also
carries the governor and parking sprag. An integral
helical gear on the transfer shaft drives the differen-
tial ring gear. The final drive gearing is completed
with one of three gear sets producing overall top gear
ratios of 2.78, 3.02, or 3.22 depending on model and
application.

FLUID LEVEL AND CONDITION
The transmission and differential sump have a
common oil sump with a communicating opening
between the two. Before removing the dipstick, wipe all dirt off of the
protective disc and the dipstick handle. The torque converter will fill in both the PPark or N
Neutral positions. Place the selector lever in PPark to
check fluid level. Inspect fluid level on dipstick every six months.
Allow the engine to idle for at least one minute
with vehicle on level ground. This will assure
complete oil level stabilization between differen-
tial and transmission. A properly filled transaxle
will read near the addmark when fluid temperature is
21 degrees Celsius (70 degrees Fahrenheit). When the
transaxle reaches operating temperature the fluid
should be in the HOTregion.
Low fluid level can cause a variety of conditions
because it allows the pump to take in air along with the
fluid. As in any hydraulic system, air bubbles make the
fluid spongy, therefore, pressures will be low and build
up slowly. Improper filling can also raise the fluid level too
high. When the transaxle has too much fluid, the gears
churn up foam and cause the same conditions which
occur with a low fluid level. In either case, the air bubbles can cause overheating,
fluid oxidation, and varnishing, which can interfere
with normal valve, clutch, and servo operation. Foam-
ing can also result in fluid escaping from the transaxle
vent (dipstick handle) where it may be mistaken for a
leak. Along with fluid level, it is important to check the
condition of the fluid. When the fluid smells burned,
and is contaminated with metal or friction material
particles, a complete transaxle overhaul is needed. Be
sure to examine the fluid on the dipstick closely. If
there is any doubt about its condition, drain out a
sample for a double check. After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.
SELECTION OF LUBRICANT
It is important that the proper lubricant be used in
these transmissions. MOPAR tATF PLUS (Automatic
Transmission Fluid-Type 7176) should be used to aid in
assuring optimum transmission performance. Fluids of
the type labeled DEXRON II Automatic Transmission
Fluid should be used only if the recommended fluid is
not available. It is important that the transmission
fluid be maintained at the prescribed level using the
recommended fluids.
SPECIAL ADDITIVES
Chrysler Corporation does not recommend the addi-
tion of any fluids to the transmission, other than the
automatic transmission fluid listed above. An ex- ception to this policy is the use of special dyes to aid in
detecting fluid leaks. The use of transmission sealers
should be avoided, since they may adversely affect
seals.
FLUID AND FILTER CHANGE
When the factory fill fluid is changed, only
fluids of the type labeled MOPAR tATF PLUS
(Automatic Transmission fluid) Type 7176 should
be used. A band adjustment and filter change
should be made at the time of the oil change. The
magnet (on the inside of the oil pan) should also
be cleaned with a clean, dry cloth. If the transaxle is disassembled for any reason,
the fluid and filter should be changed, and the
band(s) adjusted.
FLUID DRAIN AND REFILL
(1) Raise vehicle on a hoist (See Lubrication, Group
0). Place a drain container with a large opening, under
transaxle oil pan. (2) Loosen pan bolts and tap the pan at one corner to
break it loose allowing fluid to drain, then remove the
oil pan. (3) Install a new filter and gasket on bottom of the
valve body and tighten retaining screws to 5 N Im (40
in. lbs.). (4) Clean the oil pan and magnet. Reinstall pan
using new MOPAR tAdhesive sealant. Tighten oil pan
bolts to 19 N Im (165 in. lbs.).
(5) Pour four quarts of MOPAR tATF PLUS (Auto-
matic Transmission Fluid) Type 7176 through the
dipstick opening. (6) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes ap-
plied, move selector lever momentarily to each posi-
tion, ending in the park or neutral position. (7) Add sufficient fluid to bring level to 1/8 inch
below the ADD mark. Recheck fluid level after transaxle is at normal
operating temperature. The level should be in the HOT
region (Fig. 1). To prevent dirt from entering transaxle, make cer-
tain that dipstick is full seated into the dipstick open-
ing.
TORQUE CONVERTER CLUTCH SOLENOID WIRING
CONNECTOR
If wiring connector is unplugged, the torque con-
verter clutch will not operate (Fig. 2).
ROAD TEST
Prior to performing a road test, be certain that the
fluid level and condition, and control cable adjustments
have been checked and approved. During the road test, the transaxle should be oper-
ated in each position to check for slipping and any
variation in shifting.

GENERAL INFORMATION
The 41TE four-speed FWD transaxle uses fully-
adaptive controls. Adaptive controls are those which
perform their functions based on real-time feedback
sensor information. The transaxle uses hydraulically
applied clutches to shift a planetary gear train.
TRANSAXLE IDENTIFICATION
The 41TE transaxle identification code is printed
on a label. The label is located on the transaxle case
next to the solenoid assembly (Fig. 1). Refer to Figure 2 for an internal view of the tran-
saxle assembly.

FLUID LEVEL AND CONDITION
The transmission and differential sump have a
common oil sump with a communicating opening
between the two. The torque converter fills in both the PPark and N
Neutral positions. Place the selector lever in PPark to
check the fluid level. The engine should be running
at idle speed for at least one minute, with the
vehicle on level ground. This will assure com-
plete oil level stabilization between differential
and transmission. The fluid should be at normal
operating temperature (approximately 82 C. or 180 F.).
The fluid level is correct if it is in the HOTregion
(cross-hatched area) on the oil level indicator. Low fluid level can cause a variety of conditions
because it allows the pump to take in air along with the
fluid. As in any hydraulic system, air bubbles make the
fluid spongy, therefore, pressures will be low and build
up slowly. Improper filling can also raise the fluid level too
high. When the transaxle has too much fluid, the gears
churn up foam and cause the same conditions which
occur with a low fluid level. In either case, the air bubbles can cause over heat-
ing, fluid oxidation, and varnishing, which can inter-
fere with normal valve, clutch, and accumulator opera-
tion. Foaming can also result in fluid escaping from the
transaxle vent where it may be mistaken for a leak. Along with fluid level, it is important to check the
condition of the fluid. When the fluid smells burned,
and is contaminated with metal or friction material
particles, a complete transaxle overhaul is needed. Be
sure to examine the fluid on the dipstick closely. If
there is any doubt about its condition, drain out a
sample for a double check. After the fluid has been checked, seat the dipstick
fully to seal out water and dirt.
SELECTION OF LUBRICANT
It is important that the proper lubricant be used in
the 41TE transaxle. MOPAR tATF PLUS (Automatic
Transmission FluidÐtype 7176) should be used to aid
in assuring optimum transmission performance. Flu-
ids of the type labeled DEXRON II Automatic Trans-
mission Fluid are not recommended . DEXRON II
can be used only if the recommended fluid is not
available. If more than a small amount of DEXRON II
is used shudder or shift quality problems may result. It
is important that the transmission fluid be maintained
at the prescribed level using the recommended fluids.
SPECIAL ADDITIVES
Chrysler Corporation does not recommend the addi-
tion of any fluids to the transaxle, other than the
automatic transmission fluid listed above. An excep- tion to this policy is the use of special dyes to aid in
detecting fluid leaks. The use of transmission sealers
should be avoided, since they may adversely affect
seals.
FLUID AND FILTER CHANGES
When the factory fill fluid is changed, only fluids
labeled MOPAR tATF PLUS (Automatic Transmis-
sion fluid) Type 7176 should be used. A filter change
should be made at the time of the oil change. Also
the magnet (on the inside of the oil pan) should be
cleaned with a clean, dry cloth. If the transaxle is disassembled for any reason, the
fluid and filter should be changed.
FLUID DRAIN AND REFILL
(1) Raise vehicle on a hoist (See Lubrication,
Group 0). Place a drain container with a large open-
ing, under transaxle oil pan. (2) Loosen pan bolts and tap the pan at one corner
to break it loose allowing fluid to drain, then remove
the oil pan. (3) Install a new filter and O-ring on bottom of the
valve body. (4) Clean the oil pan and magnet. Reinstall pan
using new MOPAR tAdhesive Sealant. Tighten oil
pan bolts to 19 N Im (165 in. lbs.).
(5) Pour four quarts of MOPAR tATF PLUS (Au-
tomatic Transmission Fluid) Type 7176 through the
fill tube. (6) Start engine and allow to idle for at least one
minute. Then, with parking and service brakes ap-
plied, move selector lever momentarily to each posi-
tion, ending in the park or neutral position. (7) Add sufficient fluid to bring level to 1/8 inch
below the ADD mark. Recheck fluid level after transaxle is at normal op-
erating temperature. The level should be in the HOT
region (Fig. 3).
To prevent dirt from entering transaxle, make cer-
tain that dipstick is seated into the dipstick fill tube
(Fig. 4).

Prior to performing a road test, be certain that the
fluid level and condition, and control cable adjust-
ment have been checked and approved.
