V-BELT TENSION CHECKNlSFliAl
1.Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE, If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage,
of the
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.

2. If air bleeding is done while engine is runnind, ‘the air
will be
brokeir up and absorbed intti the fluid;‘?ti’ sureto do the bleeding only while cranking.
5.Connect the ignition cable, and then start the engine (idling).6. Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is
upito the specified position on the level gauge.
8.Confirm that there is very little change in the fluid level whenthe steering wheel is turned left and right.
9.Check whether or not the change in the fluid level is within5 mm
(.2 in.) when the engine is stopped and when it is
running.
Caution
1.If the change of the fluid level is 5 mm I.2 in.) or more,
the air has not been completely bled from the system,
and thus must be bled completely.2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be abnormal
noises from the pump and the flow-control valve, and
this
condition could cause a lessening of the life of the
pump, etc.

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.

Bl Kickdown brakeSHIFT PAlTERNS82 Low-reverse brake
OWC Oneway clutchTwo shift patterns are pre-stored in the control unit of this
transaxle. One is the power pattern (for more powerful
performance), and the other is the economy pattern (for
improved fuel consumption and quieter operation).
The driver can select and switch to the desired pattern by usingthe power/economy select switch on the center console.
The solid lines shown in these shift patterns indicate up-shifts,
and the broken lines indicate down-shifts. The reason why
there is a difference between the shift points for up-shifts and
for down-shifts is so that up-shifts and down-shifts will not
occur frequently when driving at a speed in the vicinity of the
shift point.
When the vehicle is stopped, there is a shift to
2nd gear in
order to obtain a suitable “creeping”, but when the accelerator
pedal is then depressed the vehicle starts off in
1st gear.

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.

EVACUATING SYSTEMWhenever the system has been opened to the atmosphere, it
is absolutely essential that the system be evacuatedor
“vacuumed” to remove all the air and moisture. Air in the
refrigerant system causes high compressor discharge
pres-sures, a loss in system performance, and oxidation of the
compressor oil into gum and varnish. Moisture in the
re-
frigerant system can cause the expansion valve to malfunction.Under certain conditions, water can react with the refrigerant
to form destructive acids. It is necessary to adhere to followingprocedure to keep air and moisture out of the system.
(1) Check to ensure that there is no internal pressure in the
equipment. If there is an internal pressure, it should be
relieved through the check valve.
(2) Connect the charging hoses of the gauge manifold to the
inlet and outlet check valves of the compressor.
(3) Connect a vacuum pump to the charging hose. Repeat
evacuation in the following sequence.
