SERVICE ADJUSTMENT
PROCEDURE |
AUTOMATIC TRANSAXLE FLUID CHECK
1. |
Drive the vehicle until the fluid temperature
rises to the normal temperature
(70~80°C). |
2. |
Park the vehicle on a level
surface. |
3. |
Move the selector lever through all positions
to fill the torque converter and the hydraulic circuits with fluid,
and then move the selector lever to the N
position. |
4. |
After wiping off any dirt around the oil level
gauge, reinsert and remove the oil level gauge and check the
condition of the fluid.
If the fluid smells as if it is burning,
it means that the fluid has been contaminated by fine
particles from the bushes and friction materials, a transaxle
overhaul may be
necessary. | |
5. |
Check that the fluid level is at the HOT mark
on the oil level gauge. If the fluid level is lower than this, add
more fluid until the level reaches the HOT mark.
Automatic transaxle fluid : DIAMOND ATF
SP-III., SK ATF SP-III.
If the fluid level is low, the oil pump
will draw in air along with the fluid, which will cause
bubbles to form inside the hydraulic circuit. This will in
turn cause the hydraulic pressure to drop, which will result
in late shifting and slipping of the clutches and brakes. If
there is too much fluid, the gears can churn it up into foam
and cause the same conditions that can occur with low fluid
levels. In either case, air bubbles can cause overheating and
oxidation of the fluid which can interfere with normal valve,
clutch, and brake operation. Foaming can also result in fluid
escaping from the transaxle vent, in which case it may be
mistaken for a
leak. | |
6. |
Insert the oil level gauge
securely. |
7. |
The fluid and the oil filters should always be
replaced when overhauling the transaxle or after the vehicle has
been driven under severe conditions. The replacement procedures are
given below. Furthermore, the oil filters are special filters which
are only to be used for the automatic transaxle.
When new, automatic transmission fluid
should be red. The red dye is added so distinguish it from
engine oil or antifreeze. As the vehicle is driven the
transmission fluid will begin to look darker. The color may
eventually appear light brown
Also, the dye, which is not an indicator
of fluid quality, is not permanent
Therefore, further investigation of the
automatic transaxle is required if,
•
|
the fluid is dark brown or
black. |
•
|
the fluid smells
burnt. |
•
|
metal particles can be seen or
felt on the
dipstick. | | |
AUTOMATIC TRANSAXLE FLUID
1. |
Remove the drain plug from the bottom of the
transaxle case to drain the fluid. |
2. |
Install the drain plug and gasket, and tighten
to the specified torque.
Tightening torque : 32 Nm (320 kgf•cm,
23 lbf•ft)
| |
3. |
Pour the new fluid in through the oil filler
tube.
Stop pouring if the full volume of fluid
cannot be poured
in. | |
4. |
Repeat the procedure in step 1 if too much
fluid was added. |
5. |
Reconnect the hose that was disconnected in
step 1 above, and firmly replace the oil level
gauge. |
6. |
Start the engine and run it at idle for 1-2
minutes. |
7. |
Move the select lever through all positions,
and then move it to the N position. |
8. |
Drive the vehicle until the fluid temperature
rises to the normal temperature (70~80°C), and then check the fluid
level again. The fluid level must be at the HOT
Mark. |
9. |
Firmly insert the oil level gauge into the oil
filler tube.


TRANSAXLE RANGE SWITCH
CONTINUITY CHECK


|
TRANSAXLE RANGE SWITCH AND CONTROL CABLE
ADJUSTMENT
1. |
Set the selector lever to the "N"
position. |
2. |
Loosen the control cable to the manual control
lever coupling nut to free the cable and
lever. |
3. |
Set the manual control lever to the neutral
position.

|
4. |
Loosen the transaxle range switch body
mounting bolts and then turn the transaxle range switch body so the
hole in the end of the manual control lever and the hole (cross
section A-A in the figure) in the flange of the transaxle range
switch body flange are aligned. |
5. |
Tighten the transaxle range switch body
mounting bolts to the specified torque. Be careful at this time that
the position of the switch body does not change.

|
6. |
Gently pull the transaxle control cable in the
direction of the arrow, then tighten the adjusting
nut. |
7. |
Check that the selector lever is in the "N"
position. |
8. |
Check that each range on the transaxle side
operates and functions correctly for each position of the selector
lever.

|
A/T CONTROL COMPONENT CHECK
1. |
THROTTLE POSITION SENSOR CHECK
The TPS is a variable resistor type that
rotates with the throttle body shaft to sense the throttle valve
angle. As the throttle shaft rotates, the output voltage of the TPS
changes. The ECM detects the throttle valve opening based on voltage
change. (Refer to FL-section). |
2. |
OIL TEMPERATURE SENSOR CHECK
(1) |
Remove the oil temperature
sensor. |
(2) |
Measure the resistance between terminals
1 and 2 of the oil temperature sensor connector.

connect a 3~10 KΩ resistance as shown in the
illustration. |
(2) |
Turn the shaft of the vehicle speed
sensor and check that there is voltage between terminals 2-3
(1 turn=4 pulses).

| |
4. |
A/T CONTROL RELAY CHECK
(1) |
Remove the A/T control
relay. |
(2) |
Use jumper wires to connect A/T control
relay terminal 2 to the battery (+) terminal and terminal 4 to
the battery (-) terminal. |

Check the continuity between terminal 1
and terminal 3 of the A/T control relay when the jumper wires
are connected and disconnected from the
battery. |

If there is a problem, replace the A/T
control relay.
