NOTE: Square cut filter cover O-rings P/N 29501469 are no longer included in High-Capacity Filter Kits
P/N 29558328 and P/N 29558329. When servicing former filter covers P/N 29507434, the required
square cut filter cover O-rings must be ordered separately. Square cut filter cover O-rings were originally
used in transmissions manufactured prior to January 22, 1996, prior to 3000 Series Product Family.
S/N 6510069120 or 4000 Series Product Family S/N 6610009730. Former filter covers can be identified
by the part number cast on the exterior side of the filter cover. Any 3000 and 4000 Series Product
Family transmissions with the former filter cover requires one square cut filter cover O-ring (4) and one
O-ring (5) (refer to Figure 1) per filter cover. O-ring (5) is included in the aforementioned high-capacity
filter kits. Some remanufactured transmissions may require the use of square cut O-rings if equipped
with the former filter covers.

NOTE: Refer to Table 9 for Filter and Gasket Kit Information, Table 10 for Fluid Capacity Information, and Figure 1
for Drain Plug and Filter Locations.
NOTE: Change fluid and filters at or before recommended mileage, months, or hours have elapsed, whichever
occurs first.
NOTE: Local conditions, severity of operation or duty cycle may require more or less frequent fluid change intervals
that differ from the published recommended fluid change intervals of Allison Transmission. Allison Transmission
recommends that customers use fluid analysis as the primary method for determining fluid change intervals. In the
absence of a fluid analysis program the fluid change intervals listed in the charts should be used.
