AUTOMATIC TRANSAXLE
_,sGENERAL INFORMATION
NZlBABTaCautionary points during disassembly and
assembly of the transaxle
Because the automatic transaxle is composed ofcomponent parts of an especially high degree of
precision, these parts should be very carefully
handled during disassembly and assembly so asnot to scar or scratch them.
A rubber mat should be placed on the work-
bench, and it should always be kept clean.
During disassembly, cloth gloves or shop towelsshould not be used.
If such items must be used, use articles made ofnylon, or use paper towels.
All
disassemblyed parts must be thoroughly
cleaned.Metal parts may be cleaned with ordinary
detergents, but must be thoroughly air dried.
Clean the clutch disc, resin thrust plate and
rubber parts by using ATF (automatic transmis-
sion fluid), being very careful that dust, dirt, etc.
do not adhere.
Do not reuse gaskets, oil seals and rubber parts.Replace them with new ones at every reassem-
bly. O-ring of oil level gauge need not be
replaced.Do not use grease other than petrolatum jelly.
Apply ATF to friction element, rotating parts, andsliding parts before installation.
New clutch disc should be immersed in ATF for
more than two hours before installation.
Do not apply sealer or adhesive to gaskets.
When bushing must be replaced, replace
assembly which includes it.
If the transaxle main unit is damaged, also
disassembly and clean the cooler system.
In order to prevent a sudden start as a result of
accidental misoperation of the select lever, this
model is provided with the automatic-transaxle
safety-lock system.

AUTOMATIC TRANSAXLE - TroubleshootingBased upon use of the troubleshooting
guide, the probable location of the prob-
lem should be estimated.
Checks should be made of fluid levels
and the condition of the ATF, as well as
bles; adjustments should then be made if

there is an abnormal condition some-
check the fault code, in order to determinethe probable location of the problem, by
When the abnormal system is discovered,
check each element (sensors, etc.) one byone, and make repairs as necessary.
“~^II_When the abnormal condition is pre-
sumed to be in the

”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.

SERVICE ADJUSTMENT PROCEDURESN21FB6E
TRANSAXLE FLUID LEVEL INSPECTION1. 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 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.
Transaxle fluid: MOPAR ATF PLUS (Automatic trans-
mission fluid type 7176) or Dia ATF SPor equivalent
Low fluid level can cause a variety of conditions
becaljse 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.
