4R75W Clutch Drum 2004, remanufactured and ready to install. Fits the 4R75W. Ships fast from the USA.
A 2004 4R75W that slips in the lower gears, takes forever to grab Drive, or comes apart with a pan full of clutch material usually needs more than a set of frictions. This remanufactured 4R75W clutch drum for 2004 replaces the drum itself, so the new clutch pack has a straight, crack-free housing and good seal surfaces to work against. The listing photo shows the drum on its long splined shaft with a clutch pack beside it, the layout of the forward clutch drum in this family.
The 4R75W is the heavier-duty member of Ford's 4R70W family of four-speed rear-drive overdrive automatics. Its forward clutch drum takes torque off the input shaft and, through the forward clutch pack, drives the forward sun gear in first, second and third. The drum also holds the piston that applies that pack, so a crack, a worn bushing or a nicked sealing ring groove bleeds off apply pressure and lets the clutches slip, overheat and glaze. Sonnax lists no forward, slipping gears, a broken clutch drum and ratio codes as the problems tied to this drum in AOD, AODE and 4R70W series units.
On the 4R70W and 4R75W the drum is often the victim of a pressure problem. Transmission Digest and Sonnax document that Ford dropped the two-bolt valve body stiffener plate for 2001, and that the change leads to forward and direct clutch problems on 2001-and-later units like this 2004. Sonnax also links low base line pressure to delayed Forward engagement and forward and direct clutch failure. ATRA's Gears magazine adds EPC faults, MAF problems, misfires and a worn pressure regulator valve bore to the list of things that burn clutches in this unit. Run a line pressure test, and check the valve body and the EPC solenoid before you close the case. Our 4R70W Expedition shift problems guide covers that diagnosis, and the 3-4 clutch failure guide covers the direct clutch, which often burns alongside the forward pack.
This drum is listed for the 2004 4R75W. The 4R70W family as a whole covers 1993 to 2008 Ford F-150, Expedition, Mustang, Crown Victoria, Grand Marquis, Town Car and Navigator, but parts changed by year. For 2004 units ATRA documents a new forward drum with three apply holes, a new ring gear and output speed sensor that do not interchange with earlier parts, and stronger late-style sun shells. Compare the shaft length, spline count and apply holes against your old drum, or send us your year and VIN and we will confirm the match. If you want the drum sold as the 2004 input drum, see the 4R75W input drum for 2004. Browse everything for this unit on the 4R70W/4R75W collection page.

The listing photo shows the drum on a long splined shaft with a clutch pack, which is how the forward clutch drum looks in this family. Compare it to your old drum, or send us your year and VIN and we will confirm before shipping.
Ford deleted the valve body stiffener plate for 2001, which Transmission Digest and Sonnax tie to forward and direct clutch problems. Low line pressure from EPC or pressure regulator wear adds to it. Fix the hydraulics or the new clutches will burn again.
Only if the drum passes inspection: no cracks, good splines, a smooth bushing and clean sealing ring grooves, and the piston holds air. A drum that leaks apply pressure will burn a new clutch pack quickly.
ATRA says the 2004-on three-hole forward drum does not change forward clutch apply. The 2004 ring gear and output speed sensor do not interchange, though, so keep the rest of the build matched to the year.
Ford lists about 13.9 quarts dry for a 2003 Crown Victoria, or 12.8 quarts with the police or handling package, and capacity varies with cooler size. Use MERCON V and check the level hot.
