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

service procedures recommended by Allison Transmission and described in this manual are

effective methods for performing troubleshooting operations. Some procedures require using

specially designed tools. Use special tools when and in the manner recommended.

The WARNINGS, CAUTIONS, and NOTES in this manual apply only to the Allison transmission

and not to other vehicle systems which may interact with the transmission. Be sure to review and

observe any vehicle system information provided by the vehicle manufacturer and/or body builder

at all times the Allison transmission is being serviced.
