5R55W 5R55S [02-UP] Automatic Transmission Master Rebuild Kit w/ Frictions

When an automatic transmission in the 5R55W, 5R55S or 5R55N family needs a full overhaul, having every friction plate, steel plate, seal and gasket accounted for in a single order is what keeps a job from stalling halfway through. What separates this set from a partial kit is the scope: soft parts and hard clutch components are included together, covering the internal rebuild from end to end without the need to cross-reference multiple part numbers.

This is a master overhaul set built for the 5R55W, 5R55S and 5R55N transmissions from 2002 onward. It does not include pistons - that is not an oversight, it is a defined boundary, and any technician planning a complete rebuild should confirm piston condition or source them separately before the job starts. The set ships at 7 lb, a weight that reflects the full count of friction plates, steel plates, seals and gaskets assembled into the box.

REMCO has been working in automatic transmission parts since 1991 and assembles every set by hand at the warehouse. Components are counted and checked against the packing list that ships inside the box, so the technician on the bench has a reference to verify the contents before the unit is opened. Nothing arrives pre-packaged from an outside source and dropped in unchecked.

Before placing the order, pull the transmission code directly off the unit. The 5R55 family uses suffix letters that indicate different internal configurations - 5R55W, 5R55S and 5R55N are each covered here, but a different suffix is a different application and requires a different set. Confirming the code takes one minute and helps avoid a return.

• Restoring a slipping or leaking automatic transmission starts with having every seal, gasket, friction plate and steel plate in one place - this set covers the full internal rebuild without hunting for pieces separately.
• This set does NOT include pistons. If your job requires new pistons, source them separately before ordering - check your parts list against what is here to avoid a second order.
• Every component in this set is hand-counted against the packing list at the time of assembly at REMCO - nothing leaves the shelf pre-packaged from a stock box, so what the list says is what goes in.
• Contents cover seals, gaskets, friction plates and steel plates for a complete overhaul; the set ships at 7 lb, which reflects the full complement of soft and hard internal parts included.
• Before ordering, confirm the exact transmission code stamped on the unit - this set fits 5R55W, 5R55S and 5R55N built from 2002 onward; a different suffix means a different application.
