DIAGNOSIS AND TEST
FLUID LEVEL AND CONDITION1. 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. This operation is necessary tobe sure that fluid level check is accurate.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the conditionof the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
lIf there is a noticeably great amount of metal particles inthe 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.
Low fluid level can cause a variety of conditions because itallows pump to take in air along with fluid. Air trapped in
hydraulic circuit forms bubbles which make fluid spongy.
Therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and
cause 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.
CONTROL CABLE
Whether control cable is properly adjusted can be confirmed bychecking whether inhibitor switch is performing well.
1. Apply parking brakes and service brakes securely.
2. Place selector lever to “R” range.
3. Set ignition key to “ST” position.
4. Slowly move the selector lever upward until it clicks as it
fits in notch of “P” range. If starter motor operates when
lever makes a click, “P” position is correct.
5.Then slowly move selector lever to “N” range by the same
procedure as in foregoing paragraph. If starter motor
operates when selector lever fits in “N”, “N” position is
correct.6. Also check to be sure the vehicle doesn’t begin to move
and the lever doesn’t stop between P-R-N-D.
7. The control cable is properly adjusted if, as described
above, the starter motor starts at both the “P” range and
the “N” range.

2. Place manual control lever in “N” (Neutral) position.
3.To adjust, rotate the switch body so that the manual controllever 5 mm
(2 in.) hole and the switch body 5 mm (.2 in.)
hole are aligned.
4.Tighten the mounting bolts of the inhibitor switch body to
the specified torque. At this time, take care to prevent
dropping the switch body.
Specified torque:
lo-12 Nm (7-9 ftlbs.)
5.Loosen the nut shown in the figure, and lightly pull the end
of the transaxle control cable in the “F” direction by hand.
6. Tighten the nut to the specified torque.
Specified torque:
IO-14 Nm (7-10 ftlbs.)7. Check that the selector lever is in “N” position.
8. Check that it securely operates and functions on the
transaxle side in the range which corresponds to each
position of the selector lever.
