Pulling the pan on a 5R110W and leaving the old filter in place puts the rest of the automatic transmission at risk, because a clogged filter starves the pump and reduces line pressure before any mechanical wear even begins. This is the filter for that job, sold as a single unit, sized and ported for the 5R110W specifically so the inlet seats correctly and fluid moves through the full circuit the way the hydraulic system expects.The 5R110W filter handles fluid drawn from the pan on every shift cycle, so the condition of the filter directly affects how cleanly the solenoids and clutch circuits respond. A filter that has been in service for an extended interval can restrict flow enough to produce soft shifts or delayed engagement without any other component being at fault. Swapping the filter during a pan service is the straightforward step that rules that variable out.This listing is a single-piece filter. It does not include a pan gasket, solenoids, friction discs, steel plates, or any external seal. If your service requires those parts, they need to be sourced separately before the job starts.Application covers 5R110W units built for the 2003 through 2007 range. Before placing the order, read the transmission code directly off the unit rather than going by the vehicle model alone, because the same vehicle line sometimes carried more than one transmission family across those years. Weight of this shipment is 1 lb. Replacing the filter at service time removes accumulated debris from the fluid circuit, helping the valve body and clutch packs work without restriction from contaminated fluid. This listing covers the filter only. It does not include gaskets, solenoids, friction discs, steels, or any seal. Review your parts list before ordering to avoid a second shipment. The filter is matched to the 5R110W unit specifically, so the inlet tube and mounting points align with the factory pan without cutting or adapting any component. Contents: one transmission filter, 1 lb. No additional pieces are packed in this shipment. Verify the part against your unit before installation. Before ordering, confirm the transmission code on the unit itself matches 5R110W and that your application falls within the 2003-2007 range covered by this part.
