COMPONENT PARTS
General Notes
The instructions here are organized so that you work on only one component group at a time.
This will help avoid confusion from similar-looking parts of different subassemblies being on
your workbench at the same time.
The component groups are inspected and repaired from the converter housing side.
As much as possible, complete the inspection, repair and assembly before proceeding to the
next component group. If a component group can not be assembled because parts are being or-
dered, be sure to keep all parts of that group in a separate container while proceeding with disas-
sembly, inspection, repair and assembly of other component groups.
Recommended fluid for the automatic transaxle: A540E ATF DEXRON
II
A540H ATF Type T or equivalent
Recommended oil for the transfer: Transaxle oil E50, API GL5, SAE 75W-90 or equivalent
GENERAL CLEANING NOTES:
1. All disassembled parts should be washed clean, with any fluid passages and holes blown
through with compressed air.
2. When using compressed air to dry parts, always aim away from yourself to prevent acciden-
tally spraying automatic transaxle fluid or kerosene in your face.
3. The recommended automatic transaxle fluid or kerosene should be used for cleaning.
PARTS ARRANGEMENT:
1. After cleaning, the parts should be arranged in proper order to allow efficient inspection,
repairs, and reassembly.
2. When disassembling a valve body, be sure to keep each valve together with the corre-
sponding spring.
3. New brakes and clutches that are to be used for replacement must be soaked in transaxle
fluid for at least fifteen minutes before assembly.
GENERAL ASSEMBLY:
1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be
coated with transmission fluid prior to reassembly.
2. All gaskets and rubber O-rings should be replaced.
3. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are
installed in the groove correctly.
4. If a worn bushing is to be replaced, the subassembly containing that bushing must be re-
placed.
5. Check thrust bearings and races for wear or damage. Replace if necessary.
6. Use petroleum jelly to keep parts in place.

A140L Automatic Transaxle
CONSTRUCTION AND OPERATION
The A140L automatic transaxle can be roughly divided into the automatic transmission section and the
differential section. The automatic transmission section is composed of the torque converter, planetary
gear unit and the hydraulic control system.
OPERATION
The pump impeller is rotated by the engine, which
causes a flow in the ATF inside the torque converter.
The flow of ATF caused by the pump impeller strikes
the turbine runner, providing a force to rotate the tur-
bine runner, and transmits torque to the input shaft.
The flow of ATF which has hit the turbine runner re-
bounds and tries to flow in the direction opposite to
the direction of rotation of the pump impeller, but the
stator returns the flow the original direction of rotation.
So the ATF
becomes a force which supports the pump impeller
and increases torque.
HINT: Although the stator is immobilized by the one-
way clutch, should the one±way clutch become de-
fective the stator will be rotated by the flow of ATF,
the flow of
ATF will not be reversed, torque will not be increased
and the problem of inadequate acceleration will occur.
The lock±up clutch is pushed against the front cover
by fluid pressure so that the engine revolutions are
directly transmitted to the input shaft without the me-
dium of the
AT F.
1. Torque Converter
CONSTRUCTION
The torque converter is composed of the pump impeller
which is rotated by the engine, the turbine runner and
lock±up clutch which are fixed to the transmission input
shaft, and the stator which is attached to the stator
shaft via the one±way clutch.
The torque converter is filled with ATF.

Preliminary Check
11. CHECK FLUID LEVEL
HINT: The vehicle must have been driven so that the
engine and transmission are at normal operating tem-
perature. (fluid temperature: 158 ± 176
°F or 70 ±80°C)
(a) Park the vehicle on a level surface, set the parking
brake.

The cooling system is composed of the water jacket (inside the cylinder block and cylinder head), radiator,
water pump, thermostat, electric fan, hoses and other components.
Coolant which is heated in the water jacket is pumped to the radiator, through which an electric fan blows air
to cool the coolant as it passes through. Coolant which has been cooled is then sent back to the engine by
the water pump, where it cools the engine.
The water jacket is a network of channels in the shell of the cylinder block and cylinder head through which
coolant passes. It is designed to provide adequate cooling of the cylinders and combustion chambers which
become heated during engine operation.
RADIATOR
The radiator performs the function of cooling the coolant which has passed through the water jacket and be-
come hot, and it is mounted in the front of the vehicle. The radiator consists of an upper tank and lower tank,
and a core which connects the two tanks. The upper tank contains the inlet for coolant from the water jacket
and the filler inlet. It also has a hose attached through which excess coolant or steam can flow. The lower
tank has an outlet and drain cock for the coolant. The core contains many tubes through which coolant flows
from the upper tank to the lower tank as well as cooling fins which radiate heat away from the coolant in the
tubes.
The air sucked through the radiator by the electric fan, as well as the wind generated by the vehicle's travel,
passes through the radiator, cooling the coolant. Models with automatic transmission include an automatic
transmission fluid cooler built into the lower tank of the radiator. A fan with an electric motor is mounted be-
hind the radiator to assist the flow of air through the radiator. The fan operates when the coolant tempera-
ture becomes high in order to prevent it from becoming too high.
RADIATOR CAP
The radiator cap is a pressure type cap which seals the radiator, resulting in pressurization of the radiator as
the coolant expands. The pressurization prevents the coolant from boiling even when the coolant tempera-
ture exceeds 100°C (212°F). A relief valve (pressurization valve) and a vacuum valve (negative pressure
valve) are built into the radiator cap. The relief valve opens and lets steam escape through the overflow pipe
when the pressure generated inside the cooling system exceeds the limit (coolant temperature: 110 ±
120°C, 230 ± 248°F, pressure; 0.3 ±1.0 kg/cm
2, 4.3 ±14.2 psi, 29.4 ± 98.1 kPa). The vacuum valve opens to
alleviate the vacuum which develops in the coolant system after the engine is stopped and the coolant tem-
perature drops.
The valves's opening allows the coolant in the reservoir tank to return to the cooling system.
RESERVOIR TANK
The reservoir tank is used to catch coolant which overflows the cooling system as a result of volumetric ex-
pansion when the coolant is heated. The coolant in the reservoir rank returns to the radiator when the cool-
ant temperature drops, thus keeping the radiator full at all times and avoiding needless coolant loss. Check
the reservoir tank level to find out if the coolant needs to be replenished.
WATER PUMP
The water pump is used for forced circulation of coolant through the cooling system. It is mounted on the
front of the cylinder block and driven by a timing belt.
THERMOSTAT
The thermostat has a wax type by±pass valve and is mounted in the water inlet housing. The thermostat in-
cludes a type of automatic valve operated by fluctuations in the coolant temperature. This valve closes when
the coolant temperature drops, preventing the circulation of coolant through the engine and thus permitting
the engine to warm up rapidly. The valve opens when the coolant temperature has risen, allowing the cir-
culation of coolant. Wax inside the thermostat expands when heated and contracts when cooled. Heating
the wax thus generates pressure which overpowers the force of the spring which keeps±the valve closed,
thus opening the valve. When the wax cools, its contraction causes the force of the spring to take effect
once more, closing the valve. The thermostat in this engine operates at a temperature of 82°C (180°F).
