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
Tighten the oil pan mounting bolts to the specified torque:

5.Add 3.8 (4.0 qts.) of the specified transmission fluid
through the filler tube.
Specified fluid:DIAMOND ATF SP IIor equivalent
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.
2. Remove the oil pan.
3.Check the oil filter for clogging and damage and re place
if necessary.
4. Clean the inside of oil pan and magnets.
5. Attach the magnets to the concave part of the oi l pan.
6. Clean both gasket surfaces of transaxle case and oil

10. Start engine and allow to idle for at least two minutes.
Then, with parking brake on, move selector lever mo men-
tarily to each position, ending in “N” Neutral
11. Check if ATF is filled up to the HOT mark on the dipstick.
