6F50 Input Drum, new and ready to install. Fits the 6F50. Ships fast from the USA.
This is a new 6F50 input drum, the 3-5-R / 4-5-6 clutch drum with the input shaft already installed, for the Ford six-speed front-drive transaxle used behind the 3.5L and 3.7L V6 in the Edge, Explorer, Flex, Taurus and Lincoln MKX. Shoppers usually land here after a teardown turned up a cracked or burned drum, or when the vehicle slips on the 3-4 shift, flares into 5th and 6th, or loses Reverse while first and second still pull fine. Because the shaft comes pressed into the drum, you are not chasing a separate turbine shaft or fighting a worn spline at the joint.
The input shaft is splined to the torque converter turbine, so this drum turns at turbine speed any time the engine is pulling the car. Inside it sit two clutch packs that Ford calls Direct (3-5-R) and Overdrive (4-5-6). The 3-5-R clutch is applied in 3rd, 5th and Reverse; the 4-5-6 clutch is applied in 4th, 5th and 6th. That means this one part carries engine torque in four of the six forward gears plus Reverse. Sonnax points out that the 35R/456 drum is one of the main places the Ford 6F50 differs from its GM 6T70 cousin, which is why a GM drum is not a substitute even though the two units look alike on the bench.
Start with the fluid level and condition, then read stored codes and watch commanded versus actual gear on a scan tool. A pattern where only the gears that share one clutch misbehave tells you which pack is involved. Compare the clutch apply chart: trouble in 3rd, 5th and Reverse is the 3-5-R side; trouble in 4th, 5th and 6th is the 4-5-6 side. Worn valve body regulator bores and solenoids can produce the same complaints without any drum damage, so rule those out first. Our Ford 6F35 and 6F50 problems guide walks through the valve body and solenoid faults that mimic hard-part failure. Once the unit is apart, air-check both pistons and inspect the sealing ring lands before deciding the drum is scrap.
The listing covers the 6F50 and the heavier-duty 6F55 in Ford and Lincoln applications from 2007 through 2020. Ford revised these transaxles more than once, so do not order on the model name alone. Check position 8 of the transmission code on the door tag (J is 6F50, C is 6F55), compare the drum, shaft length and spline count with the part you removed, and send us your year and VIN if anything does not line up. This drum does not fit the smaller 6F35 or a GM 6T70/6T75. Browse every part we carry for this family on the 6F35 / 6F50 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The input shaft is installed in the drum, so you replace the drum and shaft as one assembly. Plan on new sealing rings for the shaft during the rebuild.
The listing covers both the 6F50 and 6F55 for Ford and Lincoln vehicles from 2007 to 2020, but Ford made running changes. Match the drum and shaft against your old part or send us the year and VIN so we can check before it ships.
No. The 3-5-R and 4-5-6 drum is one of the parts that differ between the Ford and GM versions of this family, and clearances will not come out right with the wrong drum.
Plan to supply new frictions, steels and seals for both packs. A drum replacement is the right time to install a full set of soft parts, since a failed drum almost always takes its clutches with it.
Mercon LV, checked at operating temperature. After the rebuild, clear the transmission adaptive values with a capable scan tool and drive it through all six gears so shift pressures relearn.
