Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis .
In addition, used engine oil
potentially
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
lAvoid prolonged and repeated contact with oils,
particularly used engine oils.
l Wear protective clothing, including impervious
gloves where practicable.
l Avoid contaminating clothes, particularly
underpants, with oil.
l Do not put oily rags in packets, the use of
overalls without pockets will avoid this.
l Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.

harmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must
provided.
Where there is a risk of eye contact, eye protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
Obtain First Aid treatment immediately for open
cuts and wounds.
Wash regularly with soap and water to ensure
all oil is removed, especially before
cleansers and nail brushes will help). After
cleaning, the application of
containing lanolin to replace the natural
oil is advised.. .
Do not use gasoline, kerosine, diesel fuel,
oil, thinners or solvents for cleaning skin.
Use barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
If skin disorders develop, obtain medical advice
without delay.

AUTOMATIC TRANSAXLE
ENGINE (NON-TURBO)> On-vehicle Service
TORQUE CONVERTER STALL TESTING
The torque converter stall test is used primarily to determine
overrunning clutch operation.
Use the scan tool and a tachometer to
test.
Determine engine rpm with the transaxle in
at wide open throttle, and vehicle
To keep the vehicle stationary and to avoid creepin g or lurching
forward, apply both the service brakes and the parking brake.
WARNING
When performing a stall test, always apply both the ser-
vice brakes and parking brake. Also, do not let any one
stand in front of the vehicle during
NOTE
Avoid keeping the throttle open for more than 5 seconds
at a time. Allow the transmission fluid to cool
tests by placing the transaxle in neutral, raising the
rpm slightly for approximately 20 seconds.
TORQUE CONVERTER CLUTCH FAILURE
One type of over-running clutch failure is a slipping
clutch. With this type of failure, the will exhibit normal
transaxle operation at highway speeds will have poor
acceleration.
Another type of over-running clutch failure is a seized
clutch.
With this type of failure, the vehicle acceleration may be ac-
ceptable but a high throttle is required to maintai n vehicle
speed.
The vehicle may seem like it has a loss of power.
With either type of failure, poor fuel economy and transaxle
fluid over-hearting may be the result.
STALL SPEED ABOVE SPECIFICATION
If the stall speed exceeds 2,440 by more than 200
a clutch is slipping.
Diagnose the clutch circuits by performing hydrauli c and air
pressure tests.
The clutches of the transaxles may also be checked
using information given through the input and outpu t speed
sensors to the TCM.
STALL SPEED BELOW SPECIFICATION
If stall speed is below specification, the
over-running clutch is slipping. During the road te st, if poor
acceleration occurs through the gears with normal t ransaxle
operation at highway speeds, the vehicle has a slip ping
clutch.
NORMAL STALL SPEED AND ACCELERATION
If stall speed and acceleration appear normal, but it takes
excessively high throttle opening to maintain vehic le speed,
the starter’s over-running clutch is seized.
This will impede the flow of fluid within the torqu e converter,
causing excessive use of power from the engine for cruising.
CONVERTER NOISE
While performing the stall test, listen for abnormal noise com-
ing from the converter area.
A whining noise due to fluid flow within the conver ter is consid-
ered normal.
