Service Precaution 

 

WARNING: THIS VEHICLE HAS A SUPPLE MENTAL

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.

The MUA5G/5H/5S is a constant mesh transmission,
synchronized in all speeds. The transmission is
designed for a great reduction of the shift effort and the
quietest possible operation. 

 

 

Principle parts of the transmission are the integral clutch 
housing, the intermediate plate, the rear case, and the 
gears. 

The transmission control box is built into the 
transmission.
