Chrysler Stratus Convertible. Manual - part 103
GEARSHIFT PATTERN
The NV T350 (A-578) transaxle shift pattern is a
modified H–pattern (Fig. 4). Overdrive fifth and
reverse gears are in–line and outboard of the first
through fourth gear positions.
LUBRICANT/ADDITIVES
NV T350 (A-578) transaxles use Mopar
t Type M.
S. 9417 Manual Transaxle Fluid. Hypoid gear lube,
engine oil, and/or automatic transmission fluid
should not be used in this transaxle. Hard shift-
ing effort, bearing, gear, and/or synchronizer failure
may occur if incorrect fluid is used.
The addition of any fluids to the transaxle, other
than the fluid listed above, is not recommended. An
exception 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.
SEALANTS
The sealant used to seal the transaxle case halves
and input bearing is Mopar
t Gasket Maker, Loctitet
518, or equivalent. The sealant used for the bearing
end plate cover is Mopar
t RTV.
GEARSHIFT LEVERS
DESCRIPTION
The shift levers are serviceable in the vehicle. The
shift levers are different from each other and do not
interchange.
AXLE SEALS
DESCRIPTION
The axle shaft seals are identical for both sides of
the differential and will interchange.
DIAGNOSIS AND TESTING
COMMON PROBLEM CAUSES
The majority of transaxle malfunctions are a result
of:
• Insufficient lubrication
• Incorrect lubricant
• Misassembled or damaged internal components
• Improper operation
HARD SHIFTING
Hard shifting may be caused by a misadjusted
crossover cable. If hard shifting is accompanied by
gear clash, synchronizer clutch and stop rings or gear
teeth may be worn or damaged.
Misassembled synchronizer components also cause
shifting problems. Incorrectly installed synchronizer
sleeves, struts, or springs can cause shift problems.
NOISY OPERATION
Transaxle noise is most often a result of worn or
damaged components. Chipped, broken gear or syn-
chronizer teeth, and brinnelled, spalled bearings all
cause noise.
Abnormal wear and damage to the internal compo-
nents is frequently the end result of insufficient
lubricant.
SLIPS OUT OF GEAR
Transaxle disengagement may be caused by mis-
aligned or damaged shift components, or worn teeth
on the drive gears or synchronizer components. Incor-
rect assembly also causes gear disengagement.
LOW LUBRICANT LEVEL
Insufficient transaxle lubricant is usually the
result of leaks, or inaccurate fluid level check or refill
method. Leakage is evident by the presence of oil
around the leak point. If leakage is not evident, the
condition is probably the result of an underfill.
If air–powered lubrication equipment is used to fill
a transaxle, be sure the equipment is properly cali-
brated. Equipment out of calibration can lead to an
underfill condition.
