AUTOMATIC TRANSAXLE
_,sGENERAL INFORMATION
NZlBABTaCautionary points during disassembly and
assembly of the transaxle
Because the automatic transaxle is composed ofcomponent parts of an especially high degree of
precision, these parts should be very carefully
handled during disassembly and assembly so asnot to scar or scratch them.
A rubber mat should be placed on the work-
bench, and it should always be kept clean.
During disassembly, cloth gloves or shop towelsshould not be used.
If such items must be used, use articles made ofnylon, or use paper towels.
All
disassemblyed parts must be thoroughly
cleaned.Metal parts may be cleaned with ordinary
detergents, but must be thoroughly air dried.
Clean the clutch disc, resin thrust plate and
rubber parts by using ATF (automatic transmis-
sion fluid), being very careful that dust, dirt, etc.
do not adhere.
Do not reuse gaskets, oil seals and rubber parts.Replace them with new ones at every reassem-
bly. O-ring of oil level gauge need not be
replaced.Do not use grease other than petrolatum jelly.
Apply ATF to friction element, rotating parts, andsliding parts before installation.
New clutch disc should be immersed in ATF for
more than two hours before installation.
Do not apply sealer or adhesive to gaskets.
When bushing must be replaced, replace
assembly which includes it.
If the transaxle main unit is damaged, also
disassembly and clean the cooler system.
In order to prevent a sudden start as a result of
accidental misoperation of the select lever, this
model is provided with the automatic-transaxle
safety-lock system.

OBTAINING FAULT CODES(1) Connect the voltmeter to the connector for diagnosis.
(2) Read the output fault codes.
Then follow the remedy procedures according to the
“FAULT
CODE DESCRIPTION” on the following page.
NOTEl As many as a maximum of
terr fault codes, in the
sequence of occurrence, can be stored in the Random
Access Memory (RAM) incorporated within the control
unit.l If the number of stored fault codes or fault patterns
exceeds ten, already stored fault codes will be erased,
in sequence beginning with the oldest.
l Do not disconnect the battery until all fault codes or
fault patterns have been read out, because all stored
fault codes or fault patterns will be canceled when the
battery is disconnected.
(3) If the fail-safe system is activated and the transaxle is
locked in
3rd gear, the fault code in the Fail-Safe Code
Description will be stored in the RAM.
Three of these fault codes can be stored.
(4) The
cancelation will occur if, with the transaxle locked in
3rd gear, the ignition key is turned to the OFF position, but
the fault code is stored in the RAM.

SELECTOR LEVER OPERATlON CHECKNZlFlAE1. Shift selector lever to each range and check that lever
+moves smoothly and is controled. Check that position
indicator is correct.
-L*
2.Check to be sure the selector lever can be shifted to each
position (by button operation as shown in the illustration).
3. Start the engine and check if the vehicle moves forward
when the selector lever is shifted from
N to D, and moves
backward when shifted to
R.4. When the shift lever malfunctions, adjust control cable
and selector lever sleeve. Check for worn shift lever
assembly sliding parts.
NOTETo move the selector lever from the “P” position to any
other position, first turn the ignition key to any position
other than “LOCK (OFF)” and depress the brake pedal.
KEY INTERLOCK MECHANISM CHECKNZlFUAA1. Completely stop the vehicle and switch OFF the engine
before making the check.
2. Check to be sure that, under the following conditions, the
select lever cannot be moved from the “P” position to any
?cother position.
~.‘,Also check, at the same time, that the button cannot be
pressed.Ignition key position:
“LOCK (OFF)“, or removed
Brake pedal: Depressed
3.Check to be sure that, under the following conditions, the
select lever can be moved from the “P” position to any
other position.
Press the button a few times and check to be sure that the
select lever moves smoothly.
Ignition key position: “ACC”
Brake pedal : Depressed
Button
: Pressed4. Check to be sure that, at all positions of the select lever
(other than
“P”), the ignition key cannot be turned to the
“LOCK (OFF)” position.
Check to be sure that the ignition key smoothly turns to the“LOCK (OFF)” position when the select lever is then set to
the “P” position and the button is released.
5. If a malfunction is discovered when following the above
,”checking procedures, either adjust or check the key
interlock cable mechanism. (Refer to
P.21-220.)
