This publication pertains to transmissions and vehicles which are used off the public highways except where specifically
noted otherwise. Federal law restricts the removal of any part of a federally required emission control system on motor
vehicles. Further, many states have enacted laws which prohibit tampering with or modifying any required emission or
noise control system. Vehicles which are not operated on public highways are generally exempt from most regulations, as
are some special interest and pre-emission vehicles. The reader is strongly urged to check all applicable local and state laws.
Many of the parts described or listed in this manual are merchandised for off-highway application only, and are tagged with
the "Special Parts Notice" reproduced here:
