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.

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
Brake pedal: Depressed
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.
Ignition key position: “ACC”
Brake pedal : Depressed
Button
: Pressed4. Check to be sure that, at all positions of the select lever
(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
P.21-220.)
