Based on 71347mi on average before 4500hrs at Yukon depot and 55782mi on average before 4500hrs at Ulmer depot. Median value=63565mi,

increased to 66000mi to fit with 6000mi interval based schedule.

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 interval listed in the chart above should be used. Change filters according to the Table 1 & Table 2 even if a
fluid analysis shows that the fluid doesn’t need to be changed.

When the transmission contains a mixture of fluids (defined as the quantity of non-TranSynd or non-TES 295 fluid remaining in the transmission after

a fluid change combined with the quantity of TranSynd or TES295 required to fill the transmission to the proper level), perform the fluid & filter change
according to the TES389 intervals.

Extended TranSynd or TES 295 fluid & filter change intervals are only allowed with Allison High-Capacity filters.
