Product Details
✓Direct OEM Replacement: Replaces Allison 29539579, Wix 57701, and Premium Guard PT1276. The filter comes with its install gasket, so you skip sourcing a separate seal.
✓Fits 6.6L Duramax Trucks: Covers Chevrolet/GMC Silverado/Sierra 2500HD/3500HD from 2001 to 2019 behind the Allison 1000. Check your year, the 2020 model change moved to a different filter.
✓Built To Handle Load: High-flow media moves fluid freely while trapping the grit that wears torque converters and fluid pumps. Tested for filtration efficiency, dirt capacity, and burst strength.
✓Service It On Time: Swap this filter with every Allison fluid change, roughly every 25,000 to 50,000 miles and up to 60,000 at most. Change sooner if you tow or haul heavy loads.
✓Meets or exceeds OEM design, fit, and function, so it drops in as a direct replacement with no adapters or trimming.
