6L90 Clutch Drum 2007-2023, remanufactured and ready to install. Fits the 6L90. Ships fast from the USA.
If your 2007-or-newer Silverado or Sierra HD, Express or Savana van, or another 6L90 application has lost Reverse, slips in fifth, or bangs through the 2-3 and 4-5 upshifts with P0776, P2715 or P2723 stored, the clutch housing is one of the first hard parts a rebuilder checks. This listing is a remanufactured GM clutch housing referenced to GM number 24298744 (catalogued by ACDelco as an automatic transmission clutch housing), offered for 6L90 units built across the 2007 to 2023 span and covered by a 1-year warranty.
The 6L90 is a clutch-to-clutch six-speed: every shift is one clutch releasing while another applies, with the timing controlled by pressure control solenoids in the valve body. The housing in this listing is a welded steel drum that carries clutch plates and an apply piston, with apply oil delivered from the stator support through sealing rings on the hub. GM's bulletin 09-07-30-004J describes the 1-2-3-4 / 3-5-Reverse clutch housing cracking, and once it cracks it can no longer hold full apply pressure. The pack it serves loses holding power under load, the controller sees a slip ratio it does not expect, and it sets a pressure control or clutch performance code. On a heavy truck that tows, that leak shows up fastest, because the clutches are being asked to hold the most torque.
A cracked housing does not always look cracked. GM's procedure is to remove it, plug the feed holes, pressurize it with shop air and brush soapy water over the weld; bubbles mean it gets replaced. Before pulling the unit, rule out the cheaper causes that copy the same symptoms. Sonnax documents a sticking 3-5-R clutch regulator valve and a snap ring that is not seated in its groove as no-Reverse causes, and Gears Magazine points to leaking stator support gaskets and cracked stator tubes feeding the wrong clutch. Our 6L80/6L90 3-5-R clutch failure guide lays out the codes and the air test step by step, and the 6L90 3-4 clutch failure guide covers the forward-gear version of the same leak.
The listing covers 6L90 transmissions from 2007 through 2023. That is a long run, and GM revised internal parts along the way, so treat the year range as a guide rather than a guarantee. The 6L90 went into Silverado and Sierra 2500HD and 3500HD pickups, Express and Savana vans, heavy-duty Suburban and Yukon XL models, and performance cars such as the Camaro ZL1 and Corvette Z06 and ZR1. Before ordering, compare your old housing side by side with the photo: spline count, hub height and the sealing ring lands should match. If your old part carries a GM number, check it against 24298744, or send us your year and VIN and we will confirm it. Do not mix 6L80 and 6L90 internals; the 6L90 uses larger clutch components. A used original drum for the same units is listed as the 2007-up 6L90 clutch drum, and the rest of the hard parts live on the 6L90 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 6L90 units from 2007 to 2023. Because GM made running changes, match spline count, hub and ring lands to your old part, or send us your year and VIN to confirm.
It is a GM service number for an automatic transmission clutch housing. If your old housing or parts invoice shows the same number, that is the best confirmation of fit.
Not if they are burnt or glazed. A cracked housing usually overheats the pack it feeds, so plan on new frictions, steels and piston seals.
Plug the feed holes, apply shop air and spray soapy water on the weld seam. Bubbles mean it is cracked. No Reverse or fifth gear slip with P0776, P2715 or P2723 is the usual warning.
Use Dexron VI. After installation clear the transmission adaptive values and run the adaptive learn so the module relearns clutch fill times.
