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.
(Change fluid)

1.Place a drain container with a large opening, under the
transaxle oil pan.
2. Loosen the pan bolts and tap the

oil pan.
3. Install a new filter and O-ring on bottom of the valve
body.
4. Clean the oil pan and magnet.
