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
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 UNNECESSARY 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/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.
