21-202AUTOMATIC TRANSAXLE - Troubleshooting
CONVERTER STALL TESTStall test consist of determining maximum engine
speed obtained at full throttle in “D” and “R”
positions. This test checks torque converter stator
overrunning clutch operation, and holding ability of
transaxle clutches and low-reserve brake.
CautionDuring this test, make sure that no one stand in
front of or behind vehicle.
1. Check transaxle fluid level. Fluid should be at
normal operating temperature
[70-80°C (160-
18O”F)]. Engine coolant should also be at normaloperating temperature
[80-90°C (180- 19O”F)l.2. Apply chocks to both rear wheels.
3. Attach engine tachometer.
4. Apply parking and service brakes fully.
5. Start engine.
6. With selector lever in “D” position, depress
accelerator pedal fully to read engine maximum
rpm. Do not hold throttle wide open any longer
than is necessary to obtain maximum engine
rpm reading, and never longer than 5 seconds ata time. If more than one stall test is required,
operate engine at approximatey 1,000 rpm in
neutral for 2 minutes to cool transaxle fluid
between tests.
Stall speed:
1,800-3,200 rpm
TRANSAXLE CONTROL7. Place selector lever to “R” position and perform
?+stall test by the same procedure as in foregoing
-,
item.Stall Speed Above Specification in “D”
If stall speed is higher than specification, rear clutchor overrunning clutch of transaxle is slipping. In this
case, perform hydraulic test to locate cause of
slippage.Stall Speed Above Specifjcation in “R”
If stall speed is higher than specification, front
clutch of transaxle or low-reverse brake is slipping.
In this case, perform hydraulic test to locate cause
of slippage.
Stall Speed Below Specification in “D” and “R”
If stall speed is lower than specification, insufficient
engine output or faulty torque converter is sus-
pected. Check for engine misfiring, ignition timing,
valve clearance etc. If these are good, torque
converter is faulty.

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.

SELECTOR LEVER OPERATlON CHECKNZlFlAE1. Shift selector lever to each range and check that lever
+moves smoothly and is controled. Check that position
indicator is correct.
-L*
2.Check to be sure the selector lever can be shifted to each
position (by button operation as shown in the illustration).
3. Start the engine and check if the vehicle moves forward
when the selector lever is shifted from
N to D, and moves
backward when shifted to
R.4. When the shift lever malfunctions, adjust control cable
and selector lever sleeve. Check for worn shift lever
assembly sliding parts.
NOTETo move the selector lever from the “P” position to any
other position, first turn the ignition key to any position
other than “LOCK (OFF)” and depress the brake pedal.
KEY INTERLOCK MECHANISM CHECKNZlFUAA1. Completely stop the vehicle and switch OFF the engine
before making the check.
2. Check to be sure that, under the following conditions, the
select lever cannot be moved from the “P” position to any
?cother position.
~.‘,Also check, at the same time, that the button cannot be
pressed.Ignition key position:
“LOCK (OFF)“, or removed

3.Check to be sure that, under the following conditions, the
select lever can be moved from the “P” position to any
other position.
Press the button a few times and check to be sure that the
select lever moves smoothly.

(other than
“P”), the ignition key cannot be turned to the
“LOCK (OFF)” position.
Check to be sure that the ignition key smoothly turns to the“LOCK (OFF)” position when the select lever is then set to
the “P” position and the button is released.
5. If a malfunction is discovered when following the above
,”checking procedures, either adjust or check the key
interlock cable mechanism. (Refer to
