AUTOMATIC TRANSAXLE - TroubleshootingBased upon use of the troubleshooting
guide, the probable location of the prob-

Checks should be made of fluid levels
and the condition of the ATF, as well as
bles; adjustments should then be made if

”N21EeAYFunctional malfunctions of the ELC4A/T can lead to other
problems, such as those described below:
(1) Improper maintenance and/or adjustments
(2) Malfunctions of the electronic control functions
(3) Malfunctions of mechanical functions
(4) Malfunctions of hydraulic control functions
(5) Malfunctions of engine performance
etc.In order to properly determine (“Troubleshoot”) the source of
these malfunctions, it is first essential to methodically ques-
tion the user concerning the details of the problem, such qs
the condition of the problem, the situation at the time the
problem occurred, and any other relevant information, all in as
much detail as possible. The user
shoutd also be asked
whether or not the problem has occurred more than once,
and under what conditions.
Subsequently, certain tests should be conducted in a certain
order, as described at the left.

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.
