7A–23 AUTOMATIC TRANSMISSION (4L30–E)
Stall Test
The stall test allows you to check the transmission for
internal abrasion and the one way clutch for slippage.
Torque converter performance can also be evaluated.
The stall test results together with the road test results will
identify transmission components requiring servicing or
adjustment.
Stall Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid. Replenish if
necessary.
2. Block the wheels and set the parking brake.
3. Connect a tachometer to the engine.
4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Gradually push the accelerator pedal to the floor.
The throttle valve will be fully open.
Note the engine speed at which the tachometer
needle stabilizes.
Stall Speed : 2,100
150 rpm
NOTE: Do not continuously run this test longer than 5
seconds.
8. Release the accelerator pedal.
9. Place the selector in the “N” range.
10. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
11. Repeat Steps 7 – 10 for the “3”, “2”, “L” and “R”
ranges.
Line Pressure Test
The line pressure test checks oil pump and control valve
pressure regulator valve function. It will also detect oil
leakage.
Line Pressure Test Procedure:
1. Check the level of the engine coolant, the engine oil,
and the automatic transmission fluid.
Replenish if required.
2. Block the wheels and set the parking brake.
3. Remove the pressure detection plug at the left side of
the transmission case.
Set 5–8840–0004–0 pressure gauge and adapter to
the pressure detection plug hole.
241RS001
4. Start the engine and allow it to idle until the engine
coolant temperature reaches 70 – 80
C (158 –
176
F).
5. Hold the brake pedal down as far as it will go.
6. Place the selector in the “D” range.
7. Note the pressure gauge reading with the engine
idling.
8. Gradually push the accelerator pedal to the floor. The
throttle valve will be fully open.
Note the pressure gauge reading with the accelerator
pedal fully depressed.
NOTE: Do not continuously run this test longer than 5
seconds.
9. Release the accelerator pedal.
10. Place the selector in the “N” range.
11. Run the engine at 1,200 rpm for one minute.
This will cool the transmission fluid.
12. Repeat Steps 7 – 11 for the “3”, “2”, “L”, and “R”
ranges.
13. Install a pressure detection plug to the transmission
case, applying recommended thread locking agent
(LOCTITE 242) or its equivalent to thread of plug.
Make sure that thread is cleaned before applying
locking agents.
14. Tighten the pressure detection plug to the specified
torque.

Removal
1. Disconnect the battery ground cable.
2. Remove the instrument panel driver lower cover(5).
Refer to the Instrument Panel Assembly in Body
Structure section.
3. Remove seven screws to remove the steering
cowl(4).
4. Disconnect the SDM (air bag controller) connector
located at lower of the instrument panel driver lower
cover.
5. Remove four fixing screws and disconnect the driver
inflator module connector to remove the driver inflator
module(3).
CAUTION: When carrying a live inflator module,
make sure the bag opening is pointed away from
y o u . I n c a s e o f a n a c c i d e n t a l d e p l o y m e n t , t h e b a g w i l l
then deploy with minimal chance of injury. Never
carry the inflator module by the wires or connector
on the underside of the module.
When placing a live inflator module on a bench or
other surface, always face the bag and trim cover up,
away from the surface. This is necessary so that a
free space is provided to allow the air bag to expand
in the unlikely event of accidental deployment.
6. Remove the steering wheel(2).
Refer to the Steering Wheel in Steering section.
7. Disconnect the SRS coil assembly connector,
remove four fixing screws to remove the SRS coil
assembly(1).
8. Disconnect the lighting switch connector, remove four
fixing screws to remove the lighting switch(6).
825RS039
Installation
To install, follow the removal steps in the reverse order,
noting the following points.1. Check to see if the vehicle is in the straight driving
condition and turn the rotary section of the SRS coil
assembly provided to the upper surface of the lighting
switch (combination switch) counterclockwise fully
until it stops.
Then from where it stops, turn it back about 3
rotations to set the alignment marks(7) together
before installing the steering wheel.
825RW099
2. Tighten the steering shaft nut to the specified torque.
Torque: 34 Nꞏm (3.5 kgꞏm/25 lb ft)
3. When connect the double lock type of inflator module
connector, insert the connector completely and lock
at outside.
Imperfect locking may cause malfunction of SRS
system circuit.
4. When installing the steering cowl(11), be sure to pass
the harnesses through the route as shown in the
figure so that the starter switch harness(8), the
combination switch harness(9) and inflator module
harness(10) will not get caught.

Service Precaution
WARNING: IF SO EQUIPPED WITH A
SUPPLEMENTAL RESTRAINT SYSTEM (SRS),
REFER TO THE SRS COMPONENT AND WIRING
LOCATION VIEW IN ORDER TO DETERMINE
WHETHER YOU ARE PERFORMING SERVICE ON OR
NEAR THE SRS COMPONENTS OR THE SRS
WIRING. WHEN YOU ARE PERFORMING SERVICE
ON OR NEAR THE SRS COMPONENTS OR THE SRS
WIRING, REFER TO THE SRS SERVICE
INFORMATION. FAILURE TO FOLLOW WARNINGS
COULD RESULT IN POSSIBLE AIR BAG
DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.
