4L80E [91-UP] Automatic Transmission Drum Parts Direct (24209311)

When the upper clutch drum on a 4L80E or 4L85E is cracked, worn at the clutch piston bore, or otherwise damaged, replacing the drum directly is often the most efficient path to getting that automatic transmission back in service. This listing covers one single drum clutch, direct fit for the upper position, without a sprag assembly, carrying part number 24209311 and covering applications from 1997 through current production years on 4L80E and 4L85E units.

Because this is a hard part and not a seal or friction kit, the component itself does the structural work inside the unit. The drum houses the clutch pack and must be dimensionally sound for the clutch to apply and release cleanly. A drum that is out of specification or physically damaged cannot be corrected by new frictions or seals alone, which is why sourcing the drum as a standalone replacement matters on these jobs.

This piece ships at 8 lb, which reflects the solid cast construction of the drum itself. REMCO has handled automatic transmission parts since 1991 and pulls each hard part individually before it leaves, checking it against the order before boxing. The packing list ships inside the box.

What this part does not include: there is no sprag unit attached or bundled, no clutch friction discs, no steel plates, no seals, and no thrust washers. If your repair also requires a sprag or a full clutch pack, those need to be sourced separately. Verify the upper drum position is the one at fault before ordering, since the 4L80E uses more than one drum assembly and the part numbers differ by position.

Confirm the transmission code stamped on the unit reads 4L80E or 4L85E and that the model year is 1997 or later before placing your order. If there is any doubt about which drum position you need or whether the sprag is serviceable, inspect the unit before committing to this specific part.

• Restores clutch drum function in the upper position, addressing worn or damaged drum assemblies that cause slipping or no-drive conditions in 4L80E and 4L85E units.
• This is a single drum clutch part only. It does NOT include a sprag assembly, clutch packs, steels, seals, or any rebuild kit components. Verify what your repair needs before ordering.
• Designed specifically for the upper drum clutch position in 4L80E and 4L85E applications. Replacing only the drum allows targeted repairs without purchasing a full assembly when the drum itself is the failed component.
• Single piece: direct drum clutch, upper position, without sprag. Part number 24209311. Shipping weight 8 lb. No additional hardware or sub-components are included in this listing.
• Before ordering, confirm your transmission code is 4L80E or 4L85E and that the model year falls within the 1997-UP range. Also verify the drum position required is the upper and that your unit does not need the sprag version.
