CHECKING FLUID LEVEL
Check for a leak in the area of transaxle case and seal-
ing and then check fluid level and condition after remov-
ing oil level plug.
1. Operate the engine until it comes to normal operating
temperature(Coolant temperature : 80~90
°
C (176~
194
°
F)).
2. Stall the engine and raise the vehicle.
3. Remove the oil level plug and check the fluid level.
4. The fluid should slightly flow out from the oil level plug
hole.
5. If the level is low, add the recommended fluid through
the oil level plug hole until the fluid begins to run out.
6. If the fluid is contaminated or discolored, replace it
with the recommended fluid.
7. Reinstall the oil level plug and tighten it securely.

2. Stall the engine and raise the vehicle.
3. Drain the fluid after removing the drain plug.
4. Reinstall the drain plug and tighten it securely after
coating sealant.

CHECKING TRANSAXLE NOISE
Many noises that appear to come from the transaxle
may actually originate with other sources such as tires,
road surfaces, wheel bearings, or engine and exhaust
system.
Identify the cause of any noise before attempting to re-
pair the clutch, the transaxle, or their related linkages.
To verify suspected transaxle noises,
1. Select a smooth, level asphalt road to reduce tyre
and resonant body noise.
2. Drive the vehicle far enough to warm up all the lubri-
cants thoroughly.
3. Record the speed and the gear range of the transaxle
when the noise occurs.
4. Check for noises with the vehicle stopped, but with
the engine running.
5. Determine if the noise occurs while the vehicle oper-
ates in.
D
Drive – Under a light acceleration or a heavy pull.
D
Float – Maintaining a constant speed with a light
throttle on a level road.
D
Coast – With the transaxle in gear and the throttle
partly or fully closed.
D
All of the above.
CHECKING BEARING NOISE
Differential Side Bearing Noise
Differential side bearing noise and wheel bearing noise
can be confused easily. Since side bearings are pre-
loaded, a differential side bearing noise should not di-
minish much when the differential/transaxle is run with
the wheels off the ground.
Wheel Bearing Noise
Wheel bearings produce a rough growl or grating sound
that will continue when the vehicle is coasting and the
transaxle is in NEUTRAL. Since wheel bearings are not
pre-loaded, a wheel bearing noise should diminish con-
siderably when the wheels are off the ground.
