When a 5R55W, 5R55S, or 5R55N automatic transmission develops a pan leak or needs Automatic Transmission Filter service, replacing both the Automatic Transmission Filter and the pan gasket at the same time closes the job cleanly without a second teardown. This two-piece set addresses exactly that task: it contains one bonded rubber bottom pan gasket and one Automatic Transmission Filter sized 2 1/4 in, nothing more and nothing less.The bonded rubber construction on the pan gasket means the rubber is vulcanized directly to the carrier, so it holds its shape during torque-down and does not shift out of position the way loose cork or multi-piece gaskets sometimes do. The Automatic Transmission Filter fits the 5R55 family pickup tube and replaces the unit that accumulates debris over service intervals.This is not a full rebuild kit. It does not include friction clutch packs, steels, bands, internal lip seals, solenoids, or any other internal components. If your overhaul requires those parts, you will need additional pieces. Confirm what your job calls for before purchasing.REMCO has been working with automatic transmission parts since 1991. Each set like this one is assembled by hand, piece by piece, and checked against a parts list before the box is sealed. That list ships inside the box so you can verify the count the moment you open it.Applicability covers 5R55W, 5R55S, and 5R55N units from 2002 onward. Locate the transmission identification tag or the code stamped on the case to confirm your unit falls in that range before placing the order. Total shipped weight is 1 lb. Sealing the bottom pan correctly keeps fluid where it belongs and helps avoid leaks that cause pressure loss and shifting problems in 5R55 units. This set does NOT include friction discs, steel plates, bands, solenoids, or any internal sealing rings - verify you need only the Automatic Transmission Filter Kit with Pan Gasket before ordering. The pan gasket uses a bonded rubber construction that seats evenly on the pan rail, reducing the chance of uneven compression that can cause seepage over time. Contents: 1 bonded rubber bottom pan gasket and 1 Automatic Transmission Filter (2 1/4 in), 2 pieces total. Shipped weight is 1 lb. A piece list inside the box lets you confirm both items are present. Before ordering, confirm your unit is a 5R55W, 5R55S, or 5R55N built 2002 or later. The transmission code is typically on the ID tag or stamped on the case.
