AUTOMATIC TRANSMISSION ± On-vehicle Service23-19
CONVERTER STALL TEST 23100540138
In this test, the engine maximum speed when the
torque converter stalls with the shift lever in the
ªDº or ªRº range is measured to check operation
of the torque converter, starter and one-way clutch
and check holding performance of the transmission
clutch (including brake).
Caution
Do not stand in front or at rear of the vehicle
during this test.
(1) Check the transmission fluid level. The fluid
temperature should be at the level after normal
operation (70 ± 80
C). The engine coolant
temperature should also be at the level after
normal operation (80 ± 90
C).
(2) Apply chocks to the rear wheels (right and left).
(3) Mount an engine tachometer.
(4) Apply fully the parking and service brakes.(5) Start the engine.
(6) With the selector lever in the ªDº range, fully
depress the accelerator pedal and read off the
engine maximum speed.
Standard value:
2,100 ± 2,400 r/min <4G63>
2,300 ± 2,600 r/min <4D56>
NOTE
When doing so, do not keep the engine running
with throttle full open for more than 5 seconds.
If two or more stall tests are needed, place
the selector lever in the ªNº position and run
the engine at about 1,000 r/min to allow the
transmission fluid to cool before another stall
test.
(7) Place the selector lever in the ªRº range and
perform the test as above.
JUDGEMENT OF STALL TEST RESULTS
Stall speed in ªDº and ªRº range is equal to each other
but lower than the nominal value.(1) Engine output is low.
(2) Starter one-way clutch is faulty. (Faulty torque
converter is suspected if it is lower than nominal
by more than 600 r/min)
Stall speed in ªDº range is higher than nominal.(1) Overdrive clutch slipping
(2) Overdrive one-way clutch faulty
(3) Forward clutch slipping
(4) One-way clutch No. 2 faulty
(5) Low line pressure
Stall speed in ªRº range is higher than nominal.(1) Overdrive clutch slipping
(2) Overdrive one-way clutch faulty
(3) Direct clutch slipping
(4) Brake No. 3 slipping
(5) Low line pressure

FRONT AXLE ± General Information26-2
GENERAL INFORMATION26100010111
2WD
The front hub assembly which uses a double taper
roller bearing is mounted on the knuckle spindle.For vehicles with ABS, a rotor for detecting the
wheel speed is press-fitted into the front hub.
4WD
The front axle consists of the hub assembly, drive
shaft, inner shaft, front differential, freewheel clutch
assembly and actuator. The features are:

The wheel bearing uses a double taper roller
bearing. For vehicles with ABS, a rotor for
detecting the wheel speed is bolted to the brake
disc.

Drive shafts of almost identical length reduce
torque steer. In addition, a D.O.J.-B.J.-type
constant velocity ball joint has high power
transmission efficiency and reduces vibration
and noise.
A vacuum-type freewheel clutch has been
adopted in the freewheel mechanism. Its
solenoid valve and actuator switch powertrain
between 2WD and 4WD.

There are two types of differential gear. The
difference between them is gear ratio.
