10 General Information

If tools are to be stored for any length of time, it is
good policy to wipe them with an oily cloth.

Bladed screwdrivers should be checked for dam-
age to the tip. If necessary, the tip can be returned to
its original profile by careful grinding. Do not grind
screwdriver tips to a sharp point.

Hammer heads should be secure on their handles
and should be regularly checked for cracking or other
damage.

Chisels and punches should be checked for dam-
age or 'mushrooming' of the head. Any faults should
be rectified by grinding.

Hydraulic jacks should be regularly checked for
fluid leaks. Chassis stands and car ramps should be
checked for damage and cracks. Any equipment that
is suspect should not be used.

STORES
For routine maintenance, stores of automotive
oils, greases and additives should be kept on hand.
The following is a suggested list.

Engine oil.
Brake fluid.
Manual transmission or automatic transmission
oil — automatic transmission oil is also used in
the power steering system.
Rear axle oil.
Cooling system corrosion inhibitor/antifreeze.
Chassis grease.
High melting point grease, for hub bearings etc.
Penetrating oil or spray.
Kerosene or similar cleaning solvent.
Methylated spirits.

Oils and greases are available in handy pack size for
do-it-yourself lube jobs.
2. SAFETY
PERSONAL SAFETY
Safety when working on a motor vehicle is basical-
ly a matter of commonsense. Some safety precautions
to prevent personal in juries are as follows.

Raising a Vehicle
Always jack a vehicle on firm, level ground and at
the specified jacking points . Ensure that the wheels
remaining on the ground are fully chocked.

After raising the vehicle, place chassis stands
underneath and allow the weight of the vehicle to rest
on them. Do not use bricks, blocks of wood or similar
material.

NOTE: Never work under a vehicle which is
only supported by a jack.

Electrical System
Always disconnect the negative battery terminal
when working on any electrical components. Avoid
wearing metal watches, rings and chains which may
short across live terminals.

As battery gases are explosive, keep naked flames
and sparks clear of the work area. When connecting
and disconnecting jumper leads, use extreme caution
to avoid sparking.

Electronic Ignition Systems
Electronic ignition systems produce dangerous
high tension voltages in bo th the primary and second-
ary circuits which can be fatal. Exercise extreme
caution when working on or near any ignition system
components. Do not disconnect high tension leads
while the engine is running.

Work Area
Do not run the engine in a confined space. Ensure
that the work area is adequately ventilated.

Spilt oil or water should be cleaned immediately
to avoid the possibility of slipping.

Fuel System
Always disconnect the negative battery terminal
when working on any fuel components. Do not smoke.
Keep naked flames and sparks clear of the work area.

Do not siphon fuel using the mouth. Use a hand
pump or suitable siphon.

Do not attempt to repair a fuel tank by welding it.
This is an extremely hazardous procedure and should
be entrusted to a specialist.

Cooling System
To avoid scalding, use caution when releasing the
radiator cap on an engine wh ich is at normal operating
temperature. Turn the cap anti-clockwise to the first
stop and allow any pressure in the system to release.
When the pressure is released, remove the cap from
the radiator.

Brakes
As asbestos is used in some brake lining material,
avoid inhaling brake dust. Do not use compressed air
to remove the dust. Gentle brushing with a small
brush or using a vacuum cleaner with a hose attach-
ment are the safest methods of cleaning the brakes.
The above precautions also apply to the clutch plate
lining material.

General Information 11
Lifting Equipment
When using lifting equipment to lift heavy com-
ponents such as the engine and/or transmission, use
metal slings or chain in preference to rope. If rope
must be used, ensure that it is not placed against sharp
edges on the component.

Automotive Lubricants and Solvents
Avoid prolonged skin contact with oils, greases
and solvents as some can cause skin irritations and
dermatitis.

Exercise caution when us ing cleaning solvents as
many are inflammable. Do not smoke. Keep naked
flames and sparks clear of the work area.

Compressed Air
Never point an air hose at another person or allow
compressed air to blow onto your skin. High pressure
air forced against the skin can enter the bloodstream
and prove fatal.

Suspension and Steering Components
Damaged suspension and steering components
should not be welded. Many of these components are
fabricated from toughened metals. If welded they may
lose their strength or become brittle. Damaged com-
ponents should be renewed.

Air Conditioning
Avoid disconnecting air conditioning hoses as
escaping refrigerant can cause frostbite. The refriger-
ant is highly flammable and when burnt, a poisonous
gas is produced.

VEHICLE SAFETY
To prevent damage to the vehicle during servicing
or repair work, note the following precautions.

Brake Fluid
If spilt on the vehicle paintwork, brake fluid
should be immediately washed away with clean water
and allowed to dry naturally, not wiped with a cloth.

Catalytic Converter
The following should be observed to prevent
damage to the catalytic converter:

Do not operate the vehicle on leaded fuel.
Do not push or tow start the vehicle.
Do not allow the engine to idle for prolonged
periods.

Do not switch the ignition off while the vehicle is
in motion and the transmission is in gear.

Do not 'prime' the engine by pouring fuel into the
inlet manifold.

Do not operate the vehicle if the engine is
misfiring.

Avoid running the vehicle out of fuel.
Ensure that the engine oil is formulated to contain
low phosphorus levels.

Electronic Components
The electronic components of the ignition and
fuel injection systems can be damaged by the use of
incorrect testing equipment.

It is essential in all tests where voltage or resis-
tance is to be measured that a digital display multi-
meter with a minimum 10 megohm input impedance
be used.

Some types of tachometers, timing lights and
ignition system analyzers are not compatible with
certain engine electronic systems. It is therefore
recommended that the manufacturer of the test equip-
ment be consulted before using the equipment.

Jump starting, or being jump started by another
vehicle can cause damage to the electronic compon-
ents of the vehicle. Refer to the Roadside Trouble
shooting section for the correct jump starting proce-
dure.

3. GENERAL REPAIR PROCEDURES
SEIZED FASTENERS
Seized bolts, nuts or screws should first have a
liberal amount of penetrating oil applied. The fastener
should be left for a period of time to allow the oil to
penetrate and soften the corrosion which is causing
the binding.

Often, a sharp hammer blow to the head of the
fastener can dislodge the corrosion and permit it to be
loosened.

An impact driver, which can be fitted with a
socket or screwdriver bit, can be used to loosen a
seized fastener.

Another method is to heat the component in
which the fastener is seized. However, extreme cau-
tion should be exercised when heating aluminum
alloy components as the melting point is much lower
than that of steel.

If the above methods fail to free a seized nut,
carefully hacksaw through one side of the nut until it
can be split. Care should be taken that the threads of
the bolt or stud are not damaged.

Should a bolt or stud break below the surface of
the component, it will be necessary to use a screw
extractor to remove the remaining part. Follow the
screw extractor manuf acturers instructions.

2. DESCRIPTION

The automatic transaxle combines a fluid coup-
ling or torque converter with a fully automatic three
speed epicyclic gear system.

The transaxle provides th ree forward ratios and
one reverse. The hydraulic system consists of a single
pump and valv e arrangement.

The final drive or differential and the transaxle
use a common lubricant. The transaxle oil pan and
final drive drain plug will have to be removed to drain
the transaxle completely. Topping up or refilling is
done through the dipstick tube.

The gear selector lever is floor mounted and
connected to the transaxle by an adjustable cable. The
selector quadrant adjacent to the base of the lever is
marked P, R, N, D, 2, 1.

It is necessary for the selector lever to be in P or
N before the engine can be started. When testing or
tuning the engine, the handbrake must be firmly
applied and the selector lever placed in the P position,
otherwise the vehicle could move forward or back-
wards as the engine speed is increased.

For long distance towing the vehicle should be
towed with the front end raised.

It is not possible to start the engine by either
towing or pushing the vehicle.

The transaxle can be removed from the vehicle
without engine removal.

NOTE: As extensive knowledge and equip-
ment is required to overhaul the automatic
transaxle assembly, it is therefore not a
worthwhile repair proposition for the aver-
age person. However if the transaxle must
be overhauled by a specialist or be replaced
with a reconditioned unit, the removal and
installation procedure is fully described at
the end of this section.

3. TRANSAXLE FLUID
Only use the recommended transaxle fluid speci-
fied by the manufacturer when topping up or changing
the fluid in the system.

TO CHECK AND TOP UP
NOTE: The fluid level should be checked
after approximately 5 minutes driving on
the road when the engine has achieved its
normal operating temperature of approxi-
mately 65 deg C.

(1) Place the vehicle on a level floor and open
the engine bonnet.

NOTE: When working on the automatic
transaxle cleanliness is very important. Do
not reuse transaxle fluid and do not allow
foreign matter to enter the filler opening.

(2) Clean around the top of the dipstick to
ensure that no dirt or foreign matter can enter the
dipstick tube.
(3) Place the selector in the P position and
firmly apply the handbrake. (4) Move the selector thro ugh each gear return-
ing it to the P position.
(5) Check the fluid level with the engine running
at idle. Install the dipstick fully into the dipstick tube.
NOTE: If the vehicle has been driven at high
speed, or has been towing a load, or driven
through heavy city traffic in hot weather, a
period of about 30 minutes should be
allowed to permit the transaxle to cool
before checking the fluid level.

(6) Withdraw the dipstick and check the fluid
level reading. The fluid should be at the H mark on
the dipstick. If the fluid is low, stop the engine and
remove the dipstick from the vehicle. Using a funnel,
top up the transaxle with the recommended type of
transaxle fluid through the dipstick tube. (7) If the level is reading too high allow the
engine to cool down for about 30 minutes and recheck
the level as described. If the level is still too high, a
small amount of transaxle fluid may be drained from
the transaxle.

Checking the fluid level on the automatic transaxle
dipstick.

142 Automatic Transaxle
(8) Install the dipstick and start the engine and
recheck the fluid level.

NOTE; Do not overfill the transaxle or
foaming and unsatisfactory operation of the
transaxle will result.

TO DRAIN AND REFILL
This is not a normal maintenance and lubrication
procedure. It is only necessary to drain the complete
system, including the torq ue converter and the oil
cooler, when the transaxle assembly is removed for
overhaul or the renewal of transaxle components such
as bearings, clutches or as semblies. When this condi-
tion arises, the torque converter and the cooler should
be cleaned and flushed to remove any dirt or sludge.

After transaxle overhaul, install approximately 6
liters of new transaxle fluid, and top up as previously
described.

4. BRAKE BAND
Band adjustment is not a normal maintenance
procedure.

The adjustment entails removal of the valve body
and for this reason the vehicle should be taken to an
authorized dealer.

5. KICKDOWN CABLE
TO ADJUST
(1) On models with a 1.6 liter engine, remove
the air cleaner assembly. (2) With the aid of an assistant, ensure that the
throttle valve is fully open when the throttle pedal is
fully depressed. (3) Push the clip on the outer kickdown cable
and pull the cable away from the throttle linkage.

(4) Slowly depress the throttle pedal to the full
throttle position.

The outer kickdown cable will automatically ad-
just and emit a clicking noise.

6. TRANSAXLE SELECTOR LINKAGE
TO ADJUST CONTROL CABLE
(1) Place the selector lever in the Park position.
(2) Loosen the control cable locknuts and ensure
that the transaxle selector lever is in the Park position.
