When the 4-5-6 clutch pack is the source of slipping or burnt material in a 6L80E, 6L90E, or 6L80 automatic transmission, replacing the friction plates in that specific group is the focused repair this kit is built for. Unlike broader kits that bundle gaskets, seals, or steels alongside the frictions, this Friction Kit puts all six two-sided clutch discs in one box and nothing else, so you are paying for exactly the component the job calls for and not carrying extra inventory on parts you already have.The six plates included are two-sided friction discs designed for the 4-5-6 apply pack in 6L80 family units built from 2007 forward. Two-sided construction means friction material covers both faces of each plate, which keeps the clutch pack geometry consistent and ensures full surface contact on both the apply and release sides of each disc. This is the clutch group that handles the upper gear range shifts, and worn or glazed frictions in this pack are a common cause of late or soft 3-4 and 4-5 events in these units.REMCO has been working in automatic transmissions since 1991. Every kit leaves the facility hand-assembled, with each part counted against the printed parts list that ships inside the box. That list travels with the kit so the rebuilder can verify contents at the bench before teardown begins.Before placing the order, pull the identification tag or casting code from the unit and confirm it reads 6L80E, 6L90E, or 6L80. Confirm the vehicle model year falls at 2007 or later. This kit does not include seals, gaskets, steels, Automatic Transmission Filter, or any component outside the six 4-5-6 friction plates described. The 4-5-6 clutch pack in 6L80E and 6L90E units takes heavy load on every upshift; these six two-sided friction plates address wear in that specific clutch group and support a complete rebuild of that apply circuit. This kit does NOT include steel plates, seals, gaskets, Automatic Transmission Filter, bands, or any other component beyond the six 4-5-6 frictions listed. If your job requires those parts, source them separately before ordering. Six two-sided friction plates means both faces carry material, giving the 4-5-6 pack full friction surface engagement on each side without the asymmetry of single-sided discs. That geometry matters in this clutch group. Contents: 6 x 4-5-6 clutch two-sided friction plates for 6L80E, 6L90E, and 6L80 units, application range 2007 and up. Total weight: 1 lb. Each kit is assembled and checked against its parts list at REMCO before it ships. Verify the transmission code on the unit before ordering. Confirm it is a 6L80E, 6L90E, or 6L80 and that the build year falls within the 2007-and-up range covered by this friction kit.
