IT IS YOUR RESPONSIBILITY to be completely familiar with the warnings and cautions
used in this manual. These warnings and cautions advise against using specific service
procedures that can result in personal injury, equipment damage, or cause the equipment to
become unsafe. These warnings and cautions are not exhaustive. Allison Transmission could
not possibly know, evaluate, or advise the service trade of all conceivable procedures by which
service might be performed or of the possible hazardous consequences of each procedure.
Consequently, Allison Transmission has not undertaken any such broad evaluation.
Accordingly, ANYONE WHO USES A SERVICE PROCEDURE OR TOOL WHICH IS NOT
RECOMMENDED BY ALLISON TRANSMISSION MUST first be thoroughly satisfied
that neither personal safety nor equipment safety will be jeopardized by the service proce-
dures used.
Also, be sure to review and observe WARNINGS, CAUTIONS, and NOTES provided by the
vehicle manufacturer and/or body builder before servicing the Allison transmission in that
vehicle.
Proper service and repair is important to the safe and reliable operation of the equipment. The
