10L80 Clutch Module 2018, new and ready to install. Fits the 10L80. Ships fast from the USA.
This friction pack is for the owner or shop rebuilding a 2018-or-later GM 10L80 that slips, flares or has cooked its clutches. It is the Raybestos High Energy pack, part number RCP96-523, an OE replacement friction set for stock 10L80 applications in trucks and SUVs such as the Silverado, Sierra, Tahoe, Suburban, Yukon and Escalade. It replaces the frictions in every pack at once, built to meet OE performance and wear specifications, which is the right choice when the original lining wore out in normal service rather than from a big power increase.
Six multi-plate clutches, A through F, steer power through four planetary gearsets to make ten speeds. Sonnax's application charts show GM reorganized clutch apply in several gears with the Gen. 2 update in late 2019, but in both versions every shift is a release of one pack and an apply of another, timed by the TCM through individual linear solenoids. A tired pack in a ten-speed shows up in more than one gear because each pack is used in several ratios. When lining wears, clearance grows, fill time stretches out and the shift either flares or lands hard as the TCM chases it.
RCP96-523 contains 28 High Energy friction plates:
That is one fewer plate in the C pack and one fewer in the D pack than some 2017-on factory sets, which is the main thing to check against your unit. Steels, seals and the filter are sold separately.
Before you pull the transmission, make sure the clutches are actually the fault. Line pressure problems from a weak pressure control solenoid produce soft, slipping shifts on good clutches; see our 10L80 pressure control solenoid guide. A clutch control solenoid that sticks can make a single shift flare, covered in the 10L80 shift solenoid guide. If the fluid is burnt and the pan has lining material, the friction pack is the repair.
This pack is listed for 2018-on GM 10L80, and the same Raybestos pack is cataloged for the Ford 10R80 that shares the design. It is a stock-application pack; for a high-output or tuned unit look at a performance friction instead. Because plate stacking in the C and D packs differs between friction sets, lay out each pack as you take it apart and match the count before assembly. Not sure which build you have?

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It has 28 friction plates: 3 A, 5 B, 5 C, 6 D, 5 E and 4 F.
It is listed for 2018-on. For a 2017 unit, count the plates in each pack during teardown; if your C and D packs hold more plates than this pack supplies, choose a 2017 set instead.
No. It is a High Energy OE replacement material intended for stock 10L80 applications. Heavily modified units are better served by a performance friction.
Dexron ULV. GM lists a 7.7 liter (8.1 quart) service fill for the 10L80; a rebuilt dry unit will take more, so check the level hot per the factory procedure.
Seals, sealing rings, the filter and pan gasket, and any damaged steels. Worn sealing rings are a common reason new clutches slip.
