6R75 Clutch Drum, remanufactured and ready to install. Fits the 6R75. Ships fast from the USA.
If your 5.4L Expedition or Navigator with the 6R75 six-speed slips into neutral on the 2-3 shift, flares in 5th under a trailer, or takes a long, soft moment to pick up reverse, the direct clutch is the first hard part to suspect. This is a remanufactured direct (B) clutch drum for the 6R75, Ford number 9L3P-7H359-AA. It is the 5-clutch type and comes loaded, meaning the drum is supplied assembled rather than as a bare shell, and it has been cleaned, inspected and tested before it ships. Ford built the 6R75 as the middle-torque member of the 6R60/6R75/6R80 family, and this same drum number covers all three.
The 6R family is Ford's version of the ZF 6HP26. It makes six forward speeds with a Lepelletier planetary geartrain, three driving clutches (A, B and E) and two brake clutches (C and D), applied two at a time. The B clutch is the direct clutch. It works with the forward A clutch to make 3rd, with the overdrive E clutch to make 5th, and with the low-reverse brake to make reverse. The drum is the housing for that pack: it carries the apply piston, its splines hold the frictions and steels, and its sealing surfaces are where line pressure enters the piston cavity. Any leak at the drum shows up in three gears at once, which is why a B failure feels like a bigger problem than it is.
The B clutch is solenoid controlled, so a drifting shift solenoid or a worn valve body bore can starve it and look exactly like a mechanical leak. Check fluid level and condition, read codes, and watch commanded versus actual gear on a scan tool. Our 3-4 clutch failure guide walks through separating a solenoid fault from a clutch fault on this family, and the Expedition shift problems guide covers the full-size SUV side. Once the unit is apart, air-check the B circuit. A cracked piston or a leaking drum will not hold air even with new seals.
This drum is listed for the Ford and Lincoln 6R60, 6R75 and 6R80 under 9L3P-7H359-AA. In a 6R75 that means the 5.4L Expedition and Navigator applications built before the 6R80 took over. Ford did make running changes to the B pack over the years. Two apply pistons were used with different steel apply ring heights, and a 0.070 inch steel plate was added at the start of 2010. Before you install, compare the drum to your old one: friction count (this is the 5-clutch type), piston style and stack height. If you are not sure, send us your year and VIN or the tag from the case and we will check it. The rest of the family's hard parts are on our 6R60, 6R75 and 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The drum is listed under 9L3P-7H359-AA for the 6R60, 6R75 and 6R80. Ford changed the B piston and steel thickness over the years, so compare friction count, piston and stack height to your old drum, or send us your VIN.
Loaded means the drum comes assembled rather than as a bare shell, so you are not building the drum from loose parts. Still inspect it, air-check it and set clearance before installing.
Those three ranges all use the B (direct) clutch. If 1st, 2nd, 4th and 6th are fine, the B circuit is the common link: the drum, its piston, its sealing rings or the solenoid that feeds it.
Sealing rings, piston seals and gaskets from an overhaul kit, plus a filter. If the old pack burned, test the shift solenoids and check the bushings.
Early 6R units were filled with Mercon SP until Ford changed to Mercon LV for 2009. Use what Ford lists for your model year and do not mix the two.
Yes. Clear the transmission adaptive values with a scan tool and drive through normal upshifts so the computer relearns B clutch fill time.
