4L65E Input Drum 1987-2014, new and ready to install. Fits the 4L65E. Ships fast from the USA.
When a 4L65E in a Silverado, Sierra, Tahoe, Yukon, Suburban or Avalanche starts flaring on the 1-2 shift, slipping in overdrive on the highway, or backing up only after a long pause, the drum the 2-4 band wraps around is one of the first hard parts to inspect. This is a new GM drum listed under reference 24245624, the reverse input clutch housing used across the 700-R4, 4L60E and 4L65E family, which is why the listing carries a 1987-2014 span. Buy it when the band surface on your old drum is glazed, grooved or blued, or when the drum or its bushing is worn out.
The 4L65E is GM's heavy-duty take on the 4L60E, built for the 5.3L and 6.0L V8 trucks, and it uses the same layout of drums behind the pump. The reverse input drum has a working surface on each side. The 2-4 band clamps its outside diameter to hold the drum, and the sun shell it drives, stationary for 2nd and 4th gear. Inside, its own piston and clutch pack drive that same sun shell to produce Reverse. In a heavy truck that tows, the band sees a lot of heat every time the transmission shifts into overdrive, so the band surface on this drum takes a beating that the lighter 4L60E applications rarely see.
Low line pressure will slip a perfect band and drum, so test pressure first. Our 4L65E pump failure guide covers pressure loss at the pump, and the 4L65E common problems guide covers the valve body and solenoid faults that mimic hard-part wear. Sonnax also documents how a leaking 3rd accumulator checkball lowers band release pressure, which can drag and burn the band. With the unit apart, run a fingernail across the band surface, check it for dishing with a straightedge, air-check the reverse input piston and measure the bushing on the stator support.
Listed for the 4L65E with a 1987-2014 range under GM 24245624. The span reflects the years this housing was used across the transmission family, not 4L65E production alone; the 4L65E itself ran in GM full-size V8 trucks and SUVs from 2001. The listing image is a product photo, so compare the lug count, overall height and bushing bore against your core, and read the number on your old drum if it is legible. If anything looks different, send us your year and VIN and we will confirm before you order. All of our 4L65E hard parts and kits are on the 4L65E parts collection.

GM reference 24245624 is the reverse input clutch housing, the drum the 2-4 band wraps around. The input housing on the turbine shaft is a separate part listed on its own page.
This housing was used across the 700-R4, 4L60E and 4L65E family, so the range covers the whole run of the part number. The 4L65E itself was built from 2001. Match your core or send us your VIN to confirm.
Yes. A used band will not seat properly on a new drum surface, and a glazed band is often what damaged the old drum.
Yes. A leaking piston seal, a cracked drum or burnt reverse input clutches will cause slow or missing Reverse. Check line pressure and the fluid level first.
Dexron VI ATF, which GM made its service fill for these automatics. It is backward compatible with earlier Dexron fluids.
