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.

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.
