6F35 Input Drum, new and ready to install. Fits the 6F35. Ships fast from the USA.
This is a new input drum for the Ford 6F35 six-speed front-drive automatic, the clutch drum that houses the overdrive (4-5-6) clutch and drives the 3-5-R clutch through its outer lugs. Shops replace it when a 6F35 out of an Escape, Fusion, Mercury Mariner, Mazda Tribute or a later four-cylinder Ford or Lincoln comes apart with a cracked drum, broken lugs, a spun bushing or a piston bore that will not hold air. If you are hunting for a part because the transmission lost 4th, 5th and 6th, or lost Reverse along with 3rd and 5th, this drum sits at the center of that failure.
Turbine torque from the converter enters the gear train through this assembly. The 4-5-6 clutch lives inside it, so whenever the transmission is in 4th, 5th or 6th, the drum and that pack lock input speed to the planetary set. The ring of lugs around the outside carries the 3-5-R clutch plates, which apply in 3rd, 5th and Reverse. One drum therefore serves two clutches and five of the seven ranges. When it cracks, when a lug breaks, or when the bushings wear and let the sealing rings leak, pressure for both packs bleeds away and the slip shows up across several gears rather than one.
Sonnax lists 4-5-6 drum bushing wear as a known problem on every 6F35 generation. They sell a front bushing (144030-02) and a rear bushing (144030-01) for this drum and warn that they must be pressed in with an arbor press, because a hammer and driver can distort them. A drum that has run on worn bushings often shows scored bores and wear grooves, and at that point a new drum costs less than chasing the leak.
Start with the codes and which gears are affected, then match those gears to the clutches that apply in them. A worn solenoid regulator bore in the valve body can starve the same clutches and make good hard parts look bad, so check that circuit too. Our Ford 6F35 transmission problems guide covers the valve body and pressure checks in order. With the unit apart, look for cracks at the lug roots and feed holes, measure the bushings against the shaft, and air-check the piston. If the drum is sound and only the clutches burned, a 6F35 clutch module or a friction kit may be all you need.
The listing covers the Ford 6F35 and does not limit the years. Ford built the 6F35 in three generations, and drums were revised over the run, so compare this drum with yours before you install it. Check the outer lug count (the pictured drum is stamped 24), the internal hub splines, the overall height and the stamped numbers on the face. The listing gives reference number 9L8P-7J251. The pictured unit shows Ford casting marks and no input shaft. It is not the 6F50 or 6F55 part, which is larger. If you are unsure, send us your year and VIN before ordering. All of our 6F35 parts are on the 6F35 collection page.
On a budget rebuild, the used 6F35 input drum for 2009-up costs less, but it comes with used clutches and wear you will have to measure. This new drum skips that inspection risk.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. In the 6F35, the drum called the input drum holds the 4-5-6 (overdrive) clutch, and its outer lugs drive the 3-5-R clutch. Shops and catalogs use either name for this part.
The listing covers one drum assembly and does not say clutches or a shaft are included, and the pictured drum has no shaft. Plan to use new frictions, steels and seals from a rebuild kit, and reuse your input shaft if it measures good.
No. The 6F50 and 6F55 are the larger V6 units and use a bigger drum. This one is for the 6F35 only. For those transmissions, look at our separate 6F50 input drum.
Clutch slip that follows the 4-5-6 and 3-5-R gears can come from the drum or from low apply pressure. Look for cracks, broken lugs, worn bushings or a piston that leaks during an air check. Also inspect the solenoid regulator bore in the valve body, because a worn bore can cause the same symptoms.
Ford specifies Mercon LV for every 6F35. Refill with Mercon LV, set the level hot, and reset the transmission adaptive tables so the new clutch clearances are learned.
