10L90 Clutch Drum 2017-22, new and ready to install. Fits the 10L90. Ships fast from the USA.
When a 2017-2022 Silverado, Sierra, Tahoe, Yukon, Escalade or Camaro with the ten-speed starts flaring on upshifts, bumps on the coast-down, drops to neutral momentarily or throws gear ratio codes, and the air check points to the C, D and F clutches, the drum is usually where the pressure is going. This is a new aluminum CDF clutch drum, listed under OE service number JL3Z-7H351-B and interchange 164550B, for the 2017 through 2022 production years.
The GM 10L series and the Ford 10R80 it was developed alongside use six clutches, lettered A through F, and four planetary gearsets to make ten forward ratios. Three of those clutches, C, D and F, share one drum. Apply oil for each of them travels through the shaft and crosses into the drum through a pressed-in sleeve, with sealing rings riding against it and a hub bushing keeping everything centered. Sonnax's published clutch chart shows C, D and F between them working in every forward gear from second through tenth, and D and F both apply in reverse. That is why a leak in this one drum does not stay in one gear: it spreads through most of the shift schedule.
Transmission Digest lists CDF drum sleeve movement among the most common ten-speed failures and notes that the sleeve and sealing ring damage come from shift problems, not from the valve body itself.
Rule out the cheap causes first: correct fluid level at temperature, a charged battery and a clean adaptive relearn all affect how these units shift. If the complaint stays, air check the drum. Using the input and mating shaft, apply air to each of the C, D and F circuits and listen for leaks at the sleeve, sealing rings and piston. Sonnax recommends air checking the full assembly through the pump before it goes into the case. Our 10L80 clutch failure guide covers the pressure-loss pattern, and the pressure control solenoid guide helps rule out an electrical cause.
This drum is listed for 2017-2022 GM 10L80 and 10L90 transmissions and the matching Ford 10R80 and 10R90. GM changed clutch regulation for the Gen. 2 10L units starting with the 2020 models, and drum designs have been updated over the run, so set your old drum next to this one and compare the hub, sleeve and spline before installing. Match the tag on the case, not just the model year, and send us your year and VIN if you are unsure. We also carry an aftermarket enhanced version, the 10L90 CDF clutch drum 2017-2022, at a lower price. Browse more parts on our 10L80/10L90 collection page.
Plan on new C, D and F frictions and steels, new sealing rings and a new piston seal set while the drum is out; reusing heat-damaged clutches defeats the repair. Size any new solid sealing rings before assembly with a sealing ring resizer and expander kit, and use a 10-speed piston compressor and snap ring tool kit to load the clutch packs. Inspect the hub bushing surface, air check the piston, and set each clutch clearance to spec. Install a new filter and refill with DEXRON ULV, then clear adaptive values and drive the vehicle through a full relearn so the TCM learns the new clutch fill times.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2017-2022 GM 10L80 and 10L90 transmissions used in Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade and Camaro, plus the Ford 10R80 and 10R90. Compare it to your old drum and send us your year and VIN if you are unsure.
This one is listed as a new OEM aluminum drum under OE number JL3Z-7H351-B. The lower-priced listing is an aftermarket enhanced drum for the same years. Both cover the 2017-2022 range.
Air check the C, D and F circuits through the drum. Leaks at the sleeve or sealing rings point to the drum. Transmission Digest notes that sleeve movement and sealing ring damage are caused by shift issues, not the valve body.
New C, D and F friction and steel plates, sealing rings, piston seals and a filter. Inspect the hub bushing and set clutch clearances to spec during assembly.
Yes. Clear adaptive values and complete a relearn drive so the TCM learns new clutch fill times, and set the fluid level hot with DEXRON ULV.
