GENERAL Maintenance
4.Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the condition
of the fluid.
Further investigation of the transaxle is necessary if,
l the fluid smells burnt.
l the fluid color is brown or black.
l metal particles can be seen or felt on the dipstick .
5.Check to see if fluid level is in “HOT” range on dipstick.
If fluid level is low, add ATF until level reaches “HOT”
range. Low fluid level can cause a variety of condi tions
because it allows pump to take in air along with fl uid.
Air trapped in hydraulic circuit forms bubbles which make
fluid spongy.
Therefore, pressures will be erratic. Improper filling can also raise fluid level too hig h. When
transaxle has too much fluid, gears churn up foam a nd
cause same conditions which occur with low fluid le vel,
resulting in accelerated deterioration of ATF.
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 flu id
escaping from transaxle vent where it may be mistak en
for a leak.
6. Be sure to examine fluid on dipstick closely.

1.Place a drain container with a large opening, under the
transaxle oil pan.
2. Loosen the pan bolts and tap the
at one comer’
to break it loose allowing fluid to drain, then rem ove the
oil pan.
3. Install a new filter and O-ring on bottom of the valve
body.
4. Clean the oil pan and magnet.
Apply the specified sealant to the oil pan.
Specified sealant: Loctite 18718 or equivalent

5.Add 3.8 (4.0 qts.) of the specified transmission fluid
through the filler tube.

6. Start the engine and allow it to run at idle for at least
one minute. Then, with parking and service brake ap plied,
move the selector lever momentarily to each positio n,
ending in the park or neutral position.
7.Add sufficient fluid to bring to’ inch below the
ADD mark.
8.Recheck fluid level after is normal operating
temperature. The level should be in the HOT region.

Drain the fluid and check whether there is any evid ence of
contamination.
Refill with new fluid after the cause of any contam ination
has been corrected.
1. Remove drain plugs to let fluid drain.

3.Check the oil filter for clogging and damage and re place
if necessary.

or damage crankshaft flange seal surface or retaine r bore.
(3) Remove main bearing cap

(3) Install knock sensor. Tighten knock sensor to 10 Nm
(7 torque. Over or under tightening effects knock
sensor performance, possibly causing improper spark con-

(4) Select proper thickness main bearing shells by referring
to CRANKSHAFT BEARING CLEARANCE.
NOTE
Upper and lower No. 3 bearing halves are flanged to
carry the crankshaft thrust loads and are NOT inter change-
able with any other bearing halves in the engine. Bearing
shells are available in standard and the following under-
sized:
0.016 mm, 0.032 mm, 0.250 mm.
Never install an undersize bearing that will reduce clear-
ance below specifications.
(5) Install the main bearing shells with the lubric ation groove
in the cylinder block.
