4R75W Input Drum 1992, used and ready to install. Fits the 4R75W. Ships fast from the USA.
Rebuilding a Ford 4R70W-family transmission on a budget and need an input drum that is not cracked? This is a used 4R75W input drum on its long shaft, a lower-cost option than a new drum for a truck, van or full-size SUV that has lost Drive or slips in the lower gears. Read the fitment section closely, because the 1992 date on this listing needs explaining before you order.
The 4R75W is the heavier-duty member of Ford's 4R70W family, a four-speed rear-drive overdrive automatic. Turbine torque enters through the input shaft, and the drum on the end of that shaft is the forward clutch drum. When its piston applies the forward pack, the drum drives the forward sun gear. That clutch is on in first, second and third and off in fourth and Reverse, so it takes the load of every launch, every tow and every stop-and-go mile. Sonnax describes forward drum breakage as a chronic problem across the AOD, AODE and 4R70W series, which is why a cracked drum shows up so often on teardown.
Separate forward clutch symptoms from direct clutch symptoms first. Slip only in third and fourth points at the direct drum and stub shaft, not this part; our 3-4 clutch failure guide covers that side. For the forward side, check line pressure and the valve body. Sonnax ties low base line pressure to delayed Forward engagement and forward clutch failure on the 4R70W and 4R75W. The Expedition shift problems guide shows how to test pressure and solenoids before you pull the transmission.
Ford did not build a 4R75W in 1992. In that year the unit in this position was the AODE, and the 4R70W followed it; the 4R75W name came much later as the heavy-duty version of the 4R70W. The listing carries 1992 as the start of a range, and the drum design is shared across the family, so treat the year as a reference, not a guarantee. What decides fitment is the part itself. Compare the shaft length, spline count, drum height and apply holes with your old drum and with the photo. ATRA notes that 2004-and-later forward drums have three apply holes where earlier drums have one, and that 2004 also brought ring gear and speed sensor changes that do not interchange. The listing photo also shows a set of clutch plates beside the drum; ask us if you want to know exactly what ships. If your unit is a 2004 or later, the 2004 4R75W input drum is the closer match. Send us your year and VIN for a check, or browse the 4R70W and 4R75W collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. In 1992 the unit was the AODE, followed by the 4R70W, and the 4R75W came later. The 1992 date is part of the listing label. Match the drum by shaft length, splines and apply holes, or send us your year and VIN.
Yes. On the 4R70W and 4R75W the input drum is the forward clutch drum, which rides on the input shaft. The photo shows the drum on its shaft.
The photo shows plates next to the drum, but the listing names the drum. Contact us before ordering if you need to confirm what is in the box, and plan on fresh frictions and steels either way.
Probably not. Third and fourth gear slip usually points at the direct clutch drum, the stub shaft or the valve body. This drum serves first through third.
MERCON V. Do not use MERCON LV or ULV in a 4R70W or 4R75W.
Possibly, but 2004-up drums have three apply holes and 2004 brought other changes that do not interchange. For a 2004 or later unit the 2004 input drum listing is the better choice.
