Service Precaution

WARNING: THIS VEHICLE HAS 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

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/GM will call out those fasteners that require a
replacement after removal. ISUZU/GM 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.

TRANSFER CASE 7D-3

General Description

RTW57ALF000301

The transfer case is used to provide a means of
providing power flow to the front axle. The transfer case
also provides a means of disconnecting the front axle,
providing better fuel economy and quieter operation
when the vehicle is driven on improved roads where four
wheel drive is not required. In addition, the transfer case
provides an additional gear reduction when placed in low
range, which is useful when difficult off-road conditions
are encountered.

Use the 4WD switch on the center cluster panel to select
the drive range. The 4WD indicator lamp will be lit when
4WD is selected.
