SERVICE POlNTS OF REASSEMBLY18. INSTALLATION OF SUB
GEAR/17. CONE SPRING/16. SNAP RING
Install the sub gear and cone spring to 3rd speed gear, andthen install the snap ring.
NOTE
Be sure that the cone spring is installed so that it is facing inthe correct direction.
10. INSTALLATION OF SYNCHRONIZER SPRINGS
(1) Install the synchronizer spring so that its protrusion fits
into the groove in synchronizer key. Make sure that the
protrusions in the front and rear springs are not in the
in,groove of the same key.
9. INSTALLATION OF
3RD-4TH SPEED SYNCHRONIZER
ASSEMBLY
(1) Install the synchronizer assembly so that the part that
has the small round indentation is in the oil groove at
the hub end.
NOTEIf the installation is in the opposite way, press-in might
not be possible. This is because the edge of the hub
inner diameter
spline at the part that has the small
round indentation is made to facilitate pressing in.
(2) Using the special tools, press-fit the
3rd-4th speed
synchronizer assembly over the input shaft.
Caution
1. When installing the synchronizer assembly,
make sure that the three synchronizer keys are
seated correctly in their respective grooves in
the synchronizer ring.

DIAGNOSIS AND TEST
FLUID LEVEL AND CONDITION1. Drive until the fluid temperature reaches the usual tem-
perature
[70-80°C (160- 18O”F)I.2. Place vehicle on level floor.
3. Move selector lever sequentially to every position to fill
torque converter and hydraulic circuit with fluid, then place
lever in “N” Neutral position. This operation is necessary tobe sure that fluid level check is accurate.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the conditionof the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
lIf there is a noticeably great amount of metal particles inthe fluid.
5.Check to see if fluid level is in “HOT” range on dipstick. If
fluid level is low, add automatic transaxle fluid until level
reaches “HOT” range.
Low fluid level can cause a variety of conditions because itallows pump to take in air along with fluid. Air trapped in
hydraulic circuit forms bubbles which make fluid spongy.
Therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and
cause same conditions which occur with low fluid level,
resulting in accelerated deterioration of automatic transaxle
fluid.In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,
and servo operation. Foaming can also result in fluid
escaping from transaxle vent where it may be mistaken for
a leak.
6. Be sure to examine fluid on dipstick closely.
CONTROL CABLE
Whether control cable is properly adjusted can be confirmed bychecking whether inhibitor switch is performing well.
1. Apply parking brakes and service brakes securely.
2. Place selector lever to “R” range.
3. Set ignition key to “ST” position.
4. Slowly move the selector lever upward until it clicks as it
fits in notch of “P” range. If starter motor operates when
lever makes a click, “P” position is correct.
5.Then slowly move selector lever to “N” range by the same
procedure as in foregoing paragraph. If starter motor
operates when selector lever fits in “N”, “N” position is
correct.6. Also check to be sure the vehicle doesn’t begin to move
and the lever doesn’t stop between P-R-N-D.
7. The control cable is properly adjusted if, as described
above, the starter motor starts at both the “P” range and
the “N” range.

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.)
