SERVICE ADJUSTMENT PROCEDUR&g

TRANSAXLE FLUID LEVEL INSPECTION

1. Drive until the fluid temperature reaches the usual tem-
perature [70-80°C (160- 18O"F)I.
2. Place vehicle on level floor.
3. Move selector lever sequentially to every position to fill
torque converter and hydraulic circuit with fluid, then place
lever in "N" Neutral position.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the condition
of the fluid.
The transaxle should be overhauled under the following
conditions.
If there is a "burning" odor.
l
If the fluid color has become noticeably blacker.
l
If there is a noticeably great amount of metal particles in
l
the fluid.
5. Check to see if fluid level is in "HOT" range on dipstick. If
fluid level is low, add automatic transaxle fluid until level
reaches "HOT" range.
Transaxle fluid: DIAMOND ATF SP or equivalent
Low fluid level can cause a variety of conditions because it
allows pump to take in air along with fluid. Air trapped in
hydraulic circuit forms bubbles which make fluid spongy.
Therefore, pressures will be erratic, causing delayed shift,
slippy clutch and brakes, etc.
Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and
cause the same conditions which occur with low fluid level,
resulting in accelerated deterioration of automatic transaxle
fluid.
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 fluid
escaping from transaxle vent where it may be mistaken for
a leak.
6. Be sure to examine fluid on dipstick closely.
