6R140 Reaction Shell, used and ready to install. Fits the 6R140. Ships fast from the USA.
Tearing down a 6R140 out of a Super Duty and finding the intermediate drum cracked, the piston bore scored or the snap ring groove chewed up? A used factory housing is often the quickest way to get the unit back together. Although this item is listed as a reaction shell, the part you receive is the Ford 6R140 intermediate (2-6) clutch housing: the cast drum with its apply piston and pressure plate, as pictured, pulled from a 2015 gas-engine 6R140 and in clean, usable condition. The drum is marked BC3P-7L328-AE. It is a used hard part, not a rebuild kit, so plan on fresh frictions, steels and seals.
The 6R140 is a clutch-to-clutch six-speed with a simple planetary up front feeding a Ravigneaux gear set at the back. The intermediate clutch, usually called the 2-6 clutch, is a brake clutch: when it applies it holds the reaction sun gear of the rear gear set stationary, which gives you 2nd and 6th gears. Inside the drum, oil pressure pushes the apply piston against the clutch pack, and a Belleville spring held by a split ring returns it. BD Diesel's 6R140 build instructions note that early units take 8 frictions and 8 steels in this drum while later units take 7 frictions and 8 steels, and that you tell them apart by measuring from the top of the snap ring groove to the top of the drum: about 0.360 in. on early drums and about 0.450 in. on late ones.
Most 2-6 complaints are fluid, solenoid or clutch wear, not a damaged housing. Start with the 6R140 shift solenoid guide and the pressure control solenoid guide before you pull the transmission. Once it is apart, air-check the piston with the pack installed, look for cracks around the lugs and the piston bore, and check clutch clearance. BD Diesel lists an expected 2-6 clutch clearance of 0.040 to 0.060 in., measured in at least four places, and notes it is not adjustable. If it is out, a part is wrong or worn.
This housing came out of a 2015 6R140 behind a gas engine. The 6R140 was used in 2011-up F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Power Stroke and the 6.2L gas V8. Ford changed the intermediate clutch pack during production, so measure the snap ring groove depth on your old drum and compare it with this one, and match the piston and pressure plate to the frictions you are installing. If you are unsure, send us your year, VIN and the numbers on your original drum. Every part we carry for this unit is on the 6R140 parts page.
Most builders pair this housing with a 2015 6R140 banner rebuild kit for the frictions, seals and rings, and a 6R140 clutch module if the plates are burned. The seal ring expander and downsizer kit helps when the shafts go back in.

No. It is listed under that name, but the part is the 6R140 intermediate (2-6) clutch housing with its drum, apply piston and pressure plate, as shown in the photo.
It was pulled from a 2015 6R140 behind a gas engine. The 6R140 was used in 2011-up Ford F-250 through F-550 Super Duty trucks.
It is a used housing assembly. Plan on new frictions, steels and piston seals from a rebuild kit rather than reusing what is in it.
BD Diesel measures from the top of the snap ring groove to the top of the drum: about 0.360 in. on early drums and about 0.450 in. on late ones. Compare yours with this one before installing.
BD Diesel lists 0.040 to 0.060 in. for the 2-6 clutch, checked in at least four places. It is not adjustable, so out-of-range clearance means a worn or wrong part.
Yes. After any rebuild, reset the adaptive shift values with a scan tool and road test so the controller relearns clutch apply timing.
