Keep clean fluid moving through your Allison automatic and help protect its clutches and valve body with the Baldwin Transmission Oil Filter 20003. It drops in as a direct replacement across a broad range of GM, Blue Bird, Freightliner, Hino and other medium-duty trucks and buses built with the Allison LCT 1000, 2000 and 2400 series transmission — including the 2003-2004 Chevrolet Silverado 1500 6.0L, 2001-2006 Chevrolet Silverado 3500 8.1L and 2006 Hummer H1 6.6L. This part fits many additional applications — see the "Vehicles it fits" section for the full list.
As the transmission's fluid filter, it strains dirt, metal wear particles and other contaminants out of the automatic transmission fluid so cleaner oil returns to the pump, valve body and clutch packs.
