TRANSIMISSION FLUID LEVEL AND
CONDITION
Park vehicle on level ground and set parking brake.
With the engine idling, move the shift lever through all
positions from "P" to "L", then return to position "P".
Check to see If the level of fluid comes to "HOT" range
of about 80
C (176F) on the dipstick gauge.
If the level of fluid is too low, replenish to bring it to
maximum level in "HOT" range.
Inspection of fluid condition
If the ATF is black or smells burnt, replace it.
ATF REPLACEMENT
NOTE:
Do not overfill.
1) Remove the drain plug from oil pan and drain the
fluid.
2) Reinstall the drain plug securely.
3) With the engine OFF, add new fluid through the filler
tube.
4) Star t the engine and shift the selector into all
position from "P" through "L", and then shift into "P".
5) With the engine idling, check the fluid level. Add fluid
up to the "COLD" level on the dipstick.
6) The ATF level must be checked again for correct
level with the "HOT" level.
NOTE:
To prevent fluid leaks, the drain plug gasket must be
replaced each time this plug is removed.

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.
General Description
The 4L30–E is a 4–speed fully automatic transmission. It
uses a microcomputer as a control unit to judge running
conditions including throttle opening rate and vehicle
speed, then it sets the shifting point in the optimum timing
so that best driving performance can be achieved.
In addition, the built–in shift mode select function can
select three shift modes according to the driver’s
preference:
Normal mode –Normal shift pattern.
Winter mode –Starts in 3rd gear to reduce slippage on
ice or snow.
Power mode has a delayed upshift for when more
powerful acceleration is required.
Also, the built–in fail safe function (“backup mode”)
assures driving performance even if the vehicle speed
sensor, throttle signal or any solenoid fails.
Further, the self–diagnostic function conducts diagnosis
in a short time when the control system fails, thus
improving serviceability.
The major features of 4L30–E are as follows:
A compact structure consisting of 2 sets of planetary
gears and flat torque converter.
Electronic control selects the optimum shift mode
according to the driving conditions.
Electronic control maintains the optimum hydraulic
pressure for clutch, band brake as well as
transmission so that shift feeling is improved.
Two sets of planetary gears reduce friction of power
train.
Also, a lockup mechanism in the torque converter
reduces fuel consumption.
Wide gear ratio and high torque rate of torque
converter provide excellent starting performance.
