4R75W Clutch Drum 1993-2008, remanufactured and ready to install. Fits the 4R75W. Ships fast from the USA.
Heavy Ford trucks, vans and full-size SUVs work the 4R75W hard. Towing, fleet duty and long idle hours with a hot converter all add load. If yours is slipping in third, has lost its 3-4 shift or came apart with metal in the pan, the drum that carries the burnt pack is often part of the repair. This remanufactured 4R75W clutch drum lets you rebuild with a sound drum instead of reusing a cracked or worn casting.
The 4R75W is the heavier-duty member of the 4R70W family and shares its basic layout. Torque comes in through the input shaft to the forward drum. A separate intermediate stub shaft drives the direct clutch drum. A front reverse/overdrive drum is wrapped by the overdrive band. The direct clutch is fed through the output shaft at the rear of the case. The forward clutch is fed through the pump at the front. Each drum's piston needs tight sealing rings and a good bushing to build full apply pressure. Any leak means a soft apply, heat and a burnt pack.
Gears Magazine writes that third clutch failure, no 3-4 shift and planetary damage are real 4R70W/4R75W concerns, and they show up mainly in heavy-duty work vehicles. In one Ford E-Series bus it reported a burnt direct drum, an incinerated direct clutch and worn intermediate and stub shafts on the same teardown.
A drum swap only lasts if you fix what burned the pack. Transmission Digest describes a 4R75E that came in slipping in third. The bottom of the 2-3 accumulator piston had blown out, which let forward clutch oil partially apply the direct clutch until it burned. The same article lists a bonded replacement piston. Low line pressure and cross leaks do the same damage. The 3-4 clutch failure guide walks through pressure and accumulator checks. Owners of large SUVs should also read the Expedition common problems guide.
This listing is titled 4R75W clutch drum, 1993-2008, which spans the whole 4R70W/4R75W family. The 4R75W itself is the later, higher-capacity version, so read the date range as family coverage rather than proof that every model year built a 4R75W. Drums and related parts changed during production. ATRA notes the three-hole forward drum from 2004. It also notes the turbine speed sensor and its non-magnetic sun shell, and a 2007 intermediate diode with a snap-ring retainer that rides on the reverse/overdrive drum. Compare your old drum's type, height and splines with the photo, or send us your year and VIN to confirm. Browse the rest of the family in the 4R70W/4R75W collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 4R75W is the heavier-duty version of the 4R70W and shares the same basic drum layout. Sonnax sells the same 2.84/1.55-ratio direct drum kit for both. Revisions by year still matter, so match your old drum or send us your VIN.
It may be the direct drum or the clutch pack inside it. Check for a blown 2-3 accumulator piston and for low line pressure first. Transmission Digest found a damaged accumulator partially applying and burning the direct clutch.
Buy new frictions, steels, piston seals and sealing rings for that pack, plus a filter. After a heavy failure, inspect the pump, planetary and stub shaft too. Gears Magazine found shaft wear alongside a burnt direct drum.
MERCON V. Ford warns not to use MERCON LV or ULV where MERCON V is called for.
Clear any stored codes once the unit is installed. Then road test it through every gear at light and moderate throttle with the fluid fully warm to confirm clean 2-3 and 3-4 shifts.
