sealers should be avoided, since they may adversely
affect seals.
SPECIAL ADDITIVESÐRHD VEHICLES
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.

DESCRIPTION AND OPERATION
GEARSHIFT LEVERS
The gear shift levers at the transaxle are service-
able in the vehicle. The shift levers are different from
each other and do not interchange. The select lever is
not interchangeable with model years earlier than 96
(length is different).
AXLE SEALS
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:
²Insufficient lubrication
²Incorrect lubricant
²Misassembled or damaged internal components

²Improper 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.
The transaxle fill plug is located on the lower left
side of the transaxle end cover. With the vehicle at a
level position, remove the fill plug and check the
level of the lubricant. The lubricant level should be
within 3.175mm (1/8 inch) from the bottom of the fill
hole. If the lubricant level is low, fill the transaxle to
the bottom of the fill hole with SAE 5W-30 engine oil,
meeting SG and/or SG-CD qualifications, as the fac-
tory fill lubricant. SAE GL5 10W-40 engine oil is a
suitable service fill alternative.
CLUTCH PROBLEMS
Worn, damaged, or misaligned clutch components
can cause difficult shifting, gear clash, and noise.
A worn or damaged clutch disc, pressure plate, or
release bearing can cause hard shifting and gear
clash.
