4T65E Clutch Drum 1997, used and ready to install. Fits the 4T65E. Ships fast from the USA.
Searching for a 4T65E clutch drum usually starts with a teardown: the pan is full of black friction material, the car would not pull in Drive or flared into third, and now you need to know which drum you are looking at. The 4T65E has more than one. This listing is the input clutch drum, the housing on the input shaft that carries the input clutch and the 3rd clutch. It is a good used 1997-and-up GM housing that has been cleaned, polished and inspected, and it comes with its caged bearing and reconditioned steel plates. If the drum you need is the 2nd clutch housing that the reverse band wraps around, that is a different part: our 4T65E 2nd clutch drum.
Engine torque comes off the converter, through the drive chain, and into the input shaft and this housing. Inside it are two clutch packs. The input clutch works with the input one-way clutch for the forward gears, and the 3rd clutch applies on the 2-3 shift. Apply oil for both packs reaches the housing through three solid Teflon sealing rings that run inside the driven sprocket support. Because both clutches share that oil path, a worn ring land or a cracked housing does not just weaken one gear. It causes a soft start in Drive and a sloppy 2-3 shift together, and it gets worse as the fluid thins out hot.
Scan for codes and check the fluid hot. Then rule out the electrical side: TransGo calls a sticking pressure control solenoid the most common cause of P1811 on this unit, and our pressure control solenoid guide shows how to test it. Once the unit is apart, air check the input and 3rd clutches through the sprocket support. A leak you can hear, a ring groove with a step worn into it, or blued steels points to this housing. ATSG reported hot delays and 2-3 flares where the sprocket support bore, not the drum, was worn, so check both.
This housing is listed for 4T65E transaxles from 1997 up. At the start of 2003 production GM changed the input and 3rd one-way clutches to non-serviceable pawl units with 30-tooth input frictions, where earlier units use sprags and 32-tooth frictions, and Transmission Digest warns the two designs are not to be mixed. Count the teeth on an old input friction and compare this drum to yours before you install it. If you have the 2003-up design, our 2003-up input drum is built for it. For anything else on this transaxle, see the 4T65E parts page, or send us your year, model and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is the input clutch drum, also called the input housing. It carries the input clutch and the 3rd clutch on the input shaft. It is not the 2nd clutch drum, which is listed separately.
It is a good used GM housing that has been cleaned, polished and inspected. It includes the caged bearing and reconditioned steel plates. Frictions and seals are not included.
It is listed as 1997-up, but 2003 and later 4T65E units use pawl one-way clutches and 30-tooth input frictions, and the two designs are not to be mixed. Compare it with your old drum, or choose our 2003-up input drum.
New input and 3rd clutch frictions, piston seals, the three Teflon sealing rings, and a gasket and seal overhaul kit. Inspect the driven sprocket support at the same time.
Yes. Clear the transmission adapts after the repair, then drive normally for 50 to 100 shifts so the computer can relearn shift timing.
