WRECKER TOWING RECOMMENDATION
FRONT TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sli ng
type equipment to prevent the bumper from deformati on.
if this vehicle is towed, use lift type, fiat bed type
or
type equipment.
The vehicle may be towed on its rear wheels for ext ended
distances provided the parking brake is released. It is recom-
mended that vehicles be towed using the front picku p whenev-
er possible.
REAR TOWING PICKUP
Caution
1. This vehicle cannot be towed by a wrecker using
equipment to prevent the from ‘de-
formation.
if this vehicle is towed, use lift flat bed
type or doily type equipment.
2.Do not use steering lock to secure front
position for towing.
3. Make sure the transaxle is in Neutral if
will
be with drive
on the ground.. .
Automatic transaxle vehicle may be towed on the fro nt wheels
at speeds not to exceed 50 km/h (30 mph) for distan ces
not to exceed 30 km (18 miles).
C a u t i o n
if these limits cannot be met, the front
must be
placed on a tow doily or a fiat bet type must be us ed.

TOWING WHEN KEYS ARE, NOT, AVAILABLE .
When a locked vehicle must be towed and not
able, the vehicle may be lifted and towed from the front;
provided the parking brake is released. If not rele ased,. the
rear wheels should be placed on a tow dolly.
SAFETY PRECAUTIONS
The following precautions should be towing the
vehicle.
1.DO NOT LIFT OR TOW THE BY ATTACHING
TO OR WRAPPING AROUND BUMPER.
2. Any loose or protruding
of vehicle such
as hoods, doors, fenders,
etc., should be secured
or removed prior to moving
vehicle.
3.Operator should refrain going under a vehicle while
it is lifted by the towing unless the vehicle
is adequately supported by safety stands.
4. Never allow passengers to ride in a towed vehicl e.
5. State and local rules and regulations must be fo llowed
when towing a vehicle.
Caution
1.If only the front wheels or only. the rear wheels a re
lifted for towing, the bumper will be damaged.
In addition, lifting of the rear wheels causes the oil
to flow forward, and may result in heat damage to
the rear bushing of the transfer, and should never
be done.
2.Do not tow the vehicle ‘with “only front or
only the rear wheels on a dolly, or the viscous
coupling will be damaged. In a
case, the vehicle
may jump forward suddenly.
3. If this vehicle is towed, use
bed dolly
type equipment.

(1) The engine should not start even if the ignition switch
is turned to “START” position with the clutch pedal
not depressed. If the engine should start, check th e

(2) The engine should start after the clutch has be en
disconnected while the clutch pedal is depressed with
the ignition switch turned to “START” position.
If the engine should start before the clutch pedal
is disconnected or the engine does not start even
if the clutch pedal is depressed, adjust the interl ock

Stall test consists of determining maximum engine speed
obtained at full throttle in positions. This test
checks torque converter overrunning clutch operation,
and holding ability of transmission clutches and

Caution
During this test, make sure no stands in front
of, or behind, vehicle.
1.Check the transmission fluid level, fluid temperatu re and
coolant temperature.

pedal fully to read engine

throttle wide open any longer than is necessary to obtain
maximum engine rpm reading, and never longer
5 seconds at a time. If more than one stall test is required,
operate at approximately 1,000 in neutral

Stall Speed Above Specification in
If stall speed is higher than Specification, rear c lutch or overrun-
ning clutch is slipping. In this case, perform hydrau-
lic test to locate cause of slippage.
Stall Above Specification in “R”
If stall speed is higher than front clutch of trans-
axle or low-reverse brake is In this perform
hydraulic test to locate cause of slippage.
Stall Speed Above Specification and “R”
If stall speed is lower than insufficient engine
output or faulty torque converter is Check for en-
gine misfiring, ignition timing, valve clearance etc. If these
are good, torque converter is faulty..

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.
