4L80E Clutch Drum 1997, remanufactured and ready to install. Fits the 4L80E. Ships fast from the USA.
Built for the 1997 and later 4L80E, this is a remanufactured forward clutch drum with the ring gear attached, in the molded piston style. Buyers usually land here with a 1997 to 2009 Chevy or GMC 2500 or 3500, Suburban 2500, or an Express or Savana van that has lost its forward gears, slips under load in Drive, or came apart in the overdrive section and took the ring gear with it. It is the budget path to a correct, inspected forward drum without paying for a boxed new one.
Power leaves the overdrive planetary through the ring gear on the front of this drum, so the drum spins whenever the engine is driving the output. The forward clutch inside it ties the drum to the main shaft in every forward range, from Drive 1 through overdrive. On these later units the forward piston is a molded design with the seals formed onto the piston rather than separate lip seals, and the drum that carries it is the version listed here. The listing cross-references GM 24234155, superseded by 24208850.
Forward slip is not always the drum. Low line pressure, a plugged filter or a pressure control problem can burn forward clutches on a sound drum. Gauge line pressure in Drive and Reverse before you tear in. Our Sierra 2500 problems guide covers the overdrive roller clutch failure that sends debris back into this ring gear, and the Express van problems guide covers the heat and load issues that cook the forward pack in work vans. If pressure is good and forward slips while Reverse is fine, the drum, piston and clutch pack are the place to look.
This drum is for the 4L80E and 4L85E from 1997 onward, the molded piston generation. Earlier units may use a different piston style, so if you have a 1991 to 1996 transmission, compare your old drum and piston before ordering or look at the earlier forward drum we carry. Part numbers are the safest match: GM 24234155 or 24208850. Not sure? Send us your year and VIN and we will confirm fitment. The full lineup of 4L80E parts is on our 4L80E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The forward clutch piston has its sealing lips molded onto it instead of using separate seals. This drum is the 1997-up version made to work with that piston.
It is listed for 1997 and later. Earlier units may use a different piston style, so compare your drum and piston or send us your year and VIN.
The listing references GM 24234155, superseded by 24208850. Match one of those numbers to be sure.
New forward clutch plates, piston seals or a molded piston, and hub sealing rings. Inspect the overdrive planetary and the drum bushing too.
Use Dexron VI ATF and check the level with the transmission at operating temperature.
