Engineered For Complete Coverage In Routine Service

The Merchant 10075 Filter Combo provides a factory-quality solution for servicing the Allison 1000 transmission found in GM HD trucks from 2001 through 2010. Designed specifically for shallow pan applications, this kit includes both the internal transmission filter and a genuine Allison-branded external spin-on filter. Replacing both filters during a fluid service ensures proper oil filtration throughout the transmission’s pressure and return circuits, reducing the risk of debris buildup or component wear. The internal filter helps capture contaminants from within the transmission case, while the spin-on filter handles fluid returning from the cooler. This dual-layer protection supports clean shifts, stable pressure, and extended transmission life, especially under towing or heavy-duty driving conditions. Built to match OEM fit and performance, both filters install easily without the need for modifications. This kit is ideal for preventative maintenance or any full fluid service interval and is recommended by professionals who know the importance of keeping transmission systems clean and well-lubricated.
