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

Transmission
Torque Converter Clutch (TCC)
Application Conditions:
The TCC is normally applied in 2nd, 3rd and 4th gears
only when all of the following conditions exist:
The engine coolant temperature is above 70°C
(158°F).
The brake pedal is released.
The shift pattern requests TCC apply.
Moreover, TCC is always applied in 2nd, 3rd and 4th
gears when the transmission oil temperature is above
135°C (275°F).
This mode should be canceled at 125°C (257°F).
ATF Warning Lamp
The A TF warning lamp will be constantly on (not flashing)
if the transmission oil temperature is above 145°C
(293°F).
The ATF warning lamp goes off again when the
transmission oil temperature is below 125°C (257°F).
Diagnosis
Introduction
The systematic troubleshooting information covered by
this Section offers a practical and systematic approach to
diagnosing 4L30–E transmission, using information that
can be obtained from road tests, electrical diagnosis, oil
pressure checks or noise evaluation.
The key to correcting a complaint is to make use of all of
the available symptoms and logically letting them direct
you to the cause.
When dealing with automatic transmission complaints, it
is best to gather as many symptoms as possible before
making the decision to remove the transmission from the
vehicle.
Frequently, the correction of the complaint does not
require removal of the transmission from the vehicle.
Driver Information
To analyze the problem fill out a complete description of
the owner’s complaint.
Please draw a circle around the right information and
complete the following form. (The next page is an
example of a completed form.)You can draw a circle
around many numbers if you are not sure.

Checking Transmission Fluid Level
and Condition
Checking fluid level and condition (color and odor) at
regular intervals will provide early diagnosis information
about the transmission. This information may be used to
correct a condition that, if not detected early, could result
in major transmission repairs.
IMPORTANT:When new, automatic transmission fluid
is red in color. As the vehicle is driven, the transmission
fluid will begin to look darker in color. The color may
eventually appear light brown.
A dark brown color with burnt odor may indicate
excessive fluid deterioration and signal a need for fluid
change.
Fluid Level
When adding or changing fluid, use only DEXRON –III.
Refer to Maintenance and Lubrication in General
Information section for maintenance information and
servicing interval.
CAUTION:DO NOT OVERFILL.
Overfilling will cause foaming, loss of fluid, abnor-
mal shifting and possible damage to the transmis-
sion.
1.Park the vehicle on level ground and apply the parking
brake firmly.
2.Check fluid level with engine running at idle.
NOTE:Be sure that transmission fluid temperature is
below 30°C (86°F).
3.Move the selector lever through all gear ranges.
4.Move the selector lever to “Park”.
5.Let engine idle for 3 minutes and open the overfill
screw (1).
6.Add released transmission fluid until it flows out over
the overfill screw opening.
7.Let engine idle until a fluid temperature between 32°C
(90°F) and 57°C (135°F) is reached, then close the
overfill screw (1).
Torque: 38Nm(28lbft)
NOTE:To prevent fluid leaks, the overfill screw and oil
drain screws gasket must be replaced each time these
screws are removed.
NOTE:Check transmission fluid temperature with scan
tool.Minimum fluid level 57°C (135°F)
Maximum fluid level 32°C (90°F)
242RW003
CAUTION:Do not open overfill screw with engine
stopped.
CAUTION:DO NOT CHECK FLUID LEVEL UNDER
THESE CONDITIONS:
DImmediately after driving at sustained highway
speeds.
DIn heavy city traffic during hot weather.
DIf vehicle is towing a trailer.
If the vehicle has been operated under these conditions,
shut the engine off and allow the vehicle to “cool” for thirty
(30) minutes. After the cool down period, restart the
vehicle and continue from step 2 above.

Test Driving
Some 4L30–E automatic transmission complaints will
require a test drive as a part of the diagnostic procedure.
Some codes will not set unless the vehicle is moving. The
purpose of the test drive is to duplicate the customers
complaint condition and set a current Powertrain Control
Module (PCM) trouble code. Perform this procedure
before each 4L30–E automatic transmission repair, and
again after repairs are made.
IMPORTANT:
DDuplicate the condition under which the customers
complaint was observed.
DDepending on the complaint, the line pressure gauge
and the scan tool may be required during the test
drive.
DDuring the test drive, it is important to record all
necessary data from the areas being monitored, for
use in diagnosis. Also listen for and note any unusual
noises.
The following procedure should be used to test drive
4L30–E automatic transmission complaint vehicles:
1.Turn the ignition ON without starting the engine.
Check that the “CHECK TRANS” lamp comes on for
approximately 2 seconds and then goes out and
remains out.
DIf the lamp is flashing, GOTO Check Trans Indicator
in Transmission Control System (4L30–E) section.
DIf no serial data is present, GOTO OBD System
Check. Refer to Driveability and Emissions in
Engine section.
DIf the lamp stays ON or stays OFF, GOTO “Check
Trans” Check in Transmission Control System
(4L30–E) section.
2.Drive the vehicle. During the test drive, be sure that
the transmission achieves normal operating
temperature (approx. 20 minutes).
Allow the transmission to go through all of its gear
ranges, checking shift timing and firmness. Duplicate
the owners complaint condition as closely as
possible during the test drive.
3.If, during the test drive, the “CHECK TRANS” lamp
comes on, use the scan tool to check for trouble
codes.
4.If, during the test drive, a problem is felt, but the
“CHECK TRANS” lamp does not come on and no
trouble codes are present, drive the vehicle with the
PCM disconnected (manually shifting the vehicle).
DIn Manual L, the vehicle operates in first gear.
DIn Manual 2, the vehicle operates in third gear.
DIn Manual 3 or “D”, the vehicle operates in fourth
gear.
If the problem still exists with the PCM disconnected,
refer to Mechanical/Hydraulic Diagnosis in this
section.
5.If no problem has been found at this point, check all
underhood connections that supply power to the PCM
and ignition fuses. Physically and visually inspect all
the PCM harness connectors for loose or corroded
terminals. Inspect the PCM ground points.
Mechanical / Hydraulic Diagnosis Check Trans Indicator Chart
Perform Preliminary Inspection First!
When the “CHECK TRANS” indicator is flashing, it
indicates that a problem related to the transmission, the
Powertrain Control Module (PCM), or the vehicle harness
has occurred.
The system is now operating in a “BACKUP MODE”
where the risk of further damaging the transmission has
been reduced. The vehicle may be shifted manually.
If the initial problem is intermittent or seldom, switching
the engine OFF/ON might allow normal operation again
until the problem reoccurs.

Chart 13: Shudder Only During Torque Converter Clutch (TCC) Applying
Step Action YesNo
11.TCC shudder is one of the most commonly misdiagnosed
conditions in an automatic transmission. The key to
diagnosing TCC shudder is to note when it happens and under
what conditions. Once the TCC has been fully applied, it is
nearly impossible to make it shudder. TCC shudder (short
burst of noise normally less than 1 second) will only occur
during clutch applying. It is not a steady state condition.
2.Drive until whole drivetrain is at normal operating temperature.
On 4WD vehicles, the test must be performed with transfer
case selector lever in “2H” position.
Shudder is a short burst of noise normally less than 1 second
in duration, and can be induced by the following maneuver:
3.From coast condition at 50 mph in “D” range (Normal mode),
depress the throttle to 1/4-1/3 throttle. If present, shudder will
occur within 5 seconds together with TCC application.(The
scan tool may be used to determine the exact time of TCC).
Was the problem found?
Replace
transmission fluid
and filter (remove
both pans) and
flush cooler lines.
Replace
converter
assembly and
O-ring on turbine
shaft

Chart 16: Possible Causes of
Transmission Fluid Leaks
Before attempting to correct an oil leak, the actual source
of the leak must be determined. In many cases, the
source of the leak may be difficult to determine due to
“wind flow” around the engine and transmission.
The suspected area should be wiped clean before in-
specting for the source of the leak.
Oil leaks around the engine and transmission are gener-
ally carried toward the rear of the vehicle by the air
stream. In determining the source of an oil leak, the fol-
lowing two checks should be made:
1.With the engine running, check for external line
pressure leaks.
2. With the engine off, check for oil leaks due to the
raised oil level caused by drainback of converter oil
into the transmission.
