E4OD Sprag Clutch, used and ready to install. Fits the E4OD. Ships fast from the USA.
When an E4OD rebuild turns up a cracked direct drum, a sprag that spins both ways, or worn splines where the intermediate sprag rides, a good used drum is often the quickest and cheapest way to get the Ford truck or van back on the road. This listing is a used E4OD sprag clutch, and the photo shows more than a bare sprag: a clutch drum assembly with its return springs and plates, a snap ring, a tabbed thrust washer and the sprag element. It suits someone already into the transmission who needs a solid core assembly rather than a single wear part.
In the E4OD family the direct clutch housing does two jobs. Its clutch pack applies for third and fourth gear and for reverse, and the front of the housing carries the intermediate sprag. ATSG lists three one-way clutches in this design: an overdrive roller clutch, the intermediate sprag and a low roller clutch. The sprag holds in second, when the intermediate clutch locks its outer race to the case, and overruns as soon as the direct clutch applies for third. Because both elements live on the same drum, a failure in one often damages the other. A slipping direct pack overheats the drum, and a sprag that breaks up sends steel through the whole unit.
Start outside the transmission. Sonnax links direct clutch burnup, 2-3 slip and delayed reverse to oil feed leaks at the case and center support, so a replacement drum will not fix a leak in the circuit feeding it. Air-check or pressure-test the direct circuit first. Electrical faults are common on this family as well; the E4OD valve body guide and the E4OD common problems guide help separate hydraulic and electrical causes from worn hard parts. With the drum out, hold it and turn the sprag's outer race. ATSG specifies free rotation counter-clockwise and lockup clockwise.
This assembly is listed for the E4OD with no specific year, and it is used. The E4OD covered Ford F-Series pickups and E-Series vans from 1989 until the 4R100 replaced it for 1998. ATSG notes that Ford built early and late direct drums, each paired with a matching input sun shell, so match this drum's style, lug pattern and thrust washer to the one you remove and keep the sun shell that belongs with it. Send us your year, VIN and a photo of your drum if you want a second check before ordering. All of our E4OD hard parts are on the E4OD parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a clutch drum assembly along with a snap ring, a tabbed thrust washer and the sprag element. Compare it with your old drum before installing.
No, it is listed as used. Inspect the races, piston and bushing when it arrives, and install new frictions, steels and seals during the rebuild.
It is listed for the E4OD without a specific year. The E4OD was used from 1989 until the 4R100 replaced it for 1998, and Ford made early and late direct drums, so match the drum style and sun shell to your unit or send us your VIN.
Yes. The direct clutch applies for third, fourth and reverse, so a cracked drum, leaking piston or burnt pack can cause a slipping or missing third and a delayed reverse. Rule out feed leaks at the case and center support first.
We recommend new frictions and steels, set to the correct clearance, rather than reusing used plates in a rebuild.
