GENERAL REPAIR INSTRUCTIONS
1. Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
2. During disassembly, keep parts in order to facilitate
reassembly.
3. Observe the following:
(a) Before performing electrical work, disconnect the
negative cable four the battery terminal.
(b) If it is necessary to disconnect the battery for in-
spection or repair, always disconnect the cable from
the negative (-) terminal which is grounded to the
vehicle body.
(c) To prevent damage to the battery terminal post,
loosen the terminal nut and raise the cable straight
up without twisting it or prying it.
(d) Clean the battery terminal posts and cable termi-
nals with a shop rag. Do not scrape them with a file
or other abrasive object.
(e) Install the cable terminal to the battery post with the
nut loose, and tighten the nut after installation. Do
not use a hammer or such to tap the terminal onto
the post.
(f) Be sure the cover for the positive (+) terminals are
properly in place.
4. Check hoses and wiring connectors to make sure
that they are secure and correct.
5. Non-reusable parts
(a) Always replace cotter pins, gaskets, O-rings and oil
seals etc. with new ones.
(b) Non-reusable parts are indicated in the component
illustrations by the ºrº symbol.
6. Precoated parts
Precoated parts are the bolts and nuts, which have
been coated with a seal lock adhesive at the factory.
(a) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated
with the specified adhesive.
(b) Recoating of precoated parts
(1) Clean off the old adhesive from the bolt, nut
or installation part threads.
(2) Dry with compressed air.
(3) Apply the specified seal lock adhesive to the
bolt or nut threads.
(c) Precoated parts are indicated in the component il-
lustrations by the º
º symbol.

A140E Automatic Transaxle (ECT)
WHAT IS THE ECT?
ECT means Electronic Controlled Transaxle. The hydraulic control system of the previous automatic
transaxle has been changed, the throttle and governor pressure have been replaced by electronic
signals and a micro computer has been used to give precise control of shift timing and lock±up tim-
ing.
FEATURES OF THE ECT
(a) The shift pattern can be chosen.
In the ECT ECU micro computer used in the A140E, two types of shift pattern, Power and Normal,
are recorded in the memory. By operating the pattern select switch, the driver can select the pre-
ferred shift pattern.
(b) Reduced fuel consumption and reduced shock during shifting is made possible.
Precise control of the shift timing by the ECT ECU, operation of the lock±up clutch from low speeds,
and decreased fuel consumption are made possible. Also, shock during Shifting is reduced.
(e) Self±Diagnostic System
When a malfunction occurs in the electronic control system, the driver is informed of this fact. Also,
there is a Self±Diagnostic System which displays the location of the malfunction when the service
connector is shorted.
(d) Fail±Safe System
A fail±Safe System is included so that, even if a malfunction occurs in the electronic control system,
the vehicle will be able to operate.
CONSTRUCTION AND OPERATION
When the A140E (ECT) is compared with the A140L, the automatic transaxle body has the same
construction and operation, with the exception of the hydraulic control system, as the A140L.
The electronic control system, which controls the shift timing and lock±up timing, has been added.
1. Hydraulic Control System (Comparison with the A140L)
VALVE BODY ± Additions or changes to solenoid valve
In the A140E there are three solenoid valves, the No. 1, the No. 2 and the lock±up solenoid valves.
Shifting occurs according to whether the No. 1 and No. 2 solenoid valves are ON or OFF, and the
lock±up solenoid valve controls the lock±up clutch.
GOVERNOR VALVE ± Removed
With the A140E, the governor valve has been replaced with a speed sensor, so that instead of the
governor pressure, a speed sensor signal is sent to the ECT ECU.
SHIFT CONTROL IN ECT
1. The vehicle speed is sensed by the vehicle speed
sensor, which sends this data to the
ECU in the form of electrical signals.
2. The angle to which the throttle is open is sensed
by the throttle position sensor, which sends this
data to the ECU in the form of electrical signals.
3. The ECT computer determines the shift point on
the basis of these two signals and operates the
solenoid valves in the hydraulic control unit, thus
shifting the transmission.

nician.
REPLACEMENT OF FUSE AND
FUSIBLE LINK
HINT: If replacing the fuse or fusible link, be sure to
replace it with a fuse or fusible link with an equal amperage
rating.(b) Using an ohmmeter, check that there is continuity be-
tween both terminals of the circuit breaker.
If continuity is not as specified, replace the circuit breaker.
HINT: If replacing the circuit breaker, be sure to replace
it with a breaker with an equal amperage, rating.
± BODY ELECTRICAL SYSTEMGeneral InformationBE±3

NOTICE:
1. Turn off all electrical components and the ignition
switch before replacing a fuse or fusible link. Do not
exceed the fuse or fusible link amperage rating.
2. Always use a fuse puller for removing and inserting
a fuse. Remove and insert straight in and out without
twisting. Twisting could force open the terminals too
much, resulting in a bad connection.
If a fuse or fusible link continues to blow, a short circuit is
indicated. The system must be checked by a qualified tech-
nician.
