FLUID AND INTERNAL FILTER CHANGE INTERVAL
RECOMMENDATIONS
CAUTION: Transmission fluid and filter change frequency is
determined by the severity of transmission service. To help avoid
transmission damage, more frequent changes can be necessary than
recommended in the general guidelines when operating conditions create
high levels of contamination or overheating.
Allison requires all 3000 and 4000 Product Families transmissions to have the
main filter (not the lube filter or fluid) changed after the first 5000 mile (8000 km)
or 200 hours of operation, whichever comes first. Refer to the latest revision of
Service Tips #1099 for convenient kit and fluid information. Refer to Mechanic’s
Tips, latest version, for location of the main filter and the filter change procedure.
Service Tips #1099 and Mechanic’s Tips are available online at
www.allisontransmission.com.
Refer to the following Recommended Fluid/Filter Change tables for guidelines for
fluid and filter change intervals.
NOTE: Change fluid/filters at or before recommended mileage, months,
or hours have elapsed, whichever comes first. In some cases, operating
hours may represent a more reliable measure of oil life; therefore, fluid
change intervals should not be based on mileage alone.
