Filter and metal-core pan gasket for the GM 10L1000 ten-speed, replacing 24298004 (TF938) and 24297922 on 2020-2026 Silverado and Sierra HD trucks.
This kit is for owners of a 2020-and-newer Chevrolet Silverado 2500HD/3500HD or GMC Sierra 2500HD/3500HD with the 6.6L Duramax and the 10L1000 ten-speed who want the two parts that matter on every pan drop: a suction filter that replaces GM 24298004 (TF938) and a pan gasket that replaces GM 24297922. Buyers usually land here because the truck is due for a fluid and filter service after towing, because the pan flange has started to weep, or because the pan already came off for an inspection and the old gasket should not go back on.
The 10L1000 builds every gear by applying combinations of its clutches, and the off-axis pump that feeds those apply circuits draws all of its oil through the pan filter. GM catalogs 24298004 as an oil pan pump suction filter kit, which tells you exactly where it sits: between the sump and the pump inlet. Anything shed by the clutch packs, bushings or seals settles in the pan and gets caught there before it can reach the valve body. The gasket is the other half of the job. The 10L1000 pan is long, uses a lot of bolts, and lives under a truck that sees heat and frame flex while towing. The gasket in this kit uses a reinforced metal carrier with a bonded rubber bead, so the bead stays at a set crush height and the bolts cannot squeeze it out of the joint when they are tightened evenly.
Some 10L1000 complaints are not filter problems at all. Sonnax documents early or erratic converter clutch apply and engine drag on 2020-2023 3500HD trucks traced to a cracked upper valve body casting. A new filter will not cure that, so read the codes and the symptoms before you assume the pan is the answer.
Start with the fluid level, checked hot with the engine running, because low fluid causes the same whine and slow engagement as a restricted filter. Pull any stored codes, then look at what is in the pan when it comes down: a fine gray film on the magnet is ordinary wear, while flakes of friction material mean a clutch is going and the filter is only part of the repair. Our whine and clunk diagnosis guide and filter and pan service walkthrough are written around GM's light-duty ten-speed, but the checks carry straight over to the heavy-duty unit.
The listing covers 2020-2026 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD with the 10L1000. GM's own parts catalog currently lists 24298004 and 24297922 for 2020-2024 Silverado and Sierra HD trucks with 6.6L engines, and notes that 24297922 superseded the earlier gasket 24285950. Earlier gas 6.6L trucks used a six-speed instead, so confirm your truck has the 10L1000 (GM RPO MKM, MGM or MGU on the glovebox label) before you order. If you are unsure, send us your year and VIN and we will check it. Light-duty trucks with the 10L80 or 10L90 take a different filter and gasket.
If you tow heavy and want more fluid capacity and easier future services, the cast aluminum deep pan kit is the upgrade to pair with this filter. Browse more heavy-duty GM parts in our Allison and Duramax transmission parts.

It fits trucks with the 10L1000 ten-speed, used behind the 6.6L Duramax. GM's catalog lists the matching filter 24298004 and gasket 24297922 for 2020-2024 HD trucks; the listing extends coverage through 2026. Check for RPO MKM, MGM or MGU on the glovebox label, or send us your year and VIN.
DEXRON ULV only. GM TechLink lists the 10L1000 fluid change capacity at 13.6 liters, about 14.4 quarts. This kit includes no fluid, so buy it separately.
No. The gasket installs dry on clean, oil-free flanges. Sealer can push into the bead area and cause the leak you are trying to stop.
Both replace GM filter 24298004 for the 10L1000. This kit is built around a metal-core pan gasket that replaces GM 24297922. Either one covers a standard pan service.
Probably not. Sonnax traces that complaint on 2020-2023 3500HD trucks to a cracked upper valve body casting. A filter service is still worth doing, but diagnose the valve body issue separately.
Every time the pan comes off, and at the fluid change interval in your owner's manual. Heavy towing counts as severe service and shortens that interval.
