* Severe Vocation: All retarders, On/Off-Highway, Refuse, Transit, and Intercity Coach with duty cycle greater than one stop per mile.
** General Vocation: Intercity Coach with duty cycle less than or equal to one stop per mile. † Local conditions, severity of operation, or duty cycle may require more or less frequent change intervals that differ from the published recommended
fluid change intervals of Allison Transmission. Transmission protection and fluid change intervals can be optimized by the use of fluid analysis.
*** Filters must be changed at or before recommended mileage, months, or elapsed hour intervals (whichever occurs first).
