5R55W 5R55S 5R55N [99-UP] Automatic Transmission Friction Module

Once friction material glazes over, no amount of line pressure brings the holding capacity back.

5R55W Friction Module. This set replaces the wear surface that decides whether the pack holds or slips.

The spline fit decides whether the disc carries load across its full face. Shipping weight is 2 lb.

The parts list below is exactly what ships. Compare it against your teardown before ordering.

REMCO has supplied automatic transmission parts since 1991, and every order ships with its part listing so the receiving technician can check what arrived against what was ordered.

• One order covers all four clutch packs: 17 friction plates counted, verified against the part list, and packed at REMCO before the box closes -- no sourcing four sets separately.
• This kit contains friction plates only -- no steel plates, no Automatic Transmission Filter, no seals, no gaskets, no band. Confirm what your rebuild still needs before ordering to avoid a return trip.
• Four distinct clutch applications in a single shipment: 5 direct clutch internal spline, 5 direct clutch external spline, 5 forward clutch (.069 thick, 5.230 OD, 89 teeth), and 2 overdrive clutch (.069 spiral groove) -- each counted at packing.
• Contents: 5 frictions direct clutch 1-sided internal spline, 5 frictions direct clutch 1-sided external spline, 5 frictions forward clutch (.069 / 5.230 OD / 89 teeth), 2 frictions overdrive clutch (.069 spiral groove). Total 17 plates. Kit weight 2 lb.
• Before ordering verify the transmission code stamped on the unit -- 5R55W, 5R55S, or 5R55N -- and confirm model year falls within the 99-ON range. The overdrive clutch plates in this kit also cross to 4R44E and 4R55E 97-UP units.
