6R140 Clutch Drum 2015, new and ready to install. Fits the 6R140. Ships fast from the USA.
This page is for the 6.7L Power Stroke owner or rebuilder with a 2015-and-later 6R140 that is slipping, flaring between gears or showing burnt friction material in the pan. The listing is titled as a clutch drum, but what ships is a new BorgWarner high energy friction clutch set, kit 35725KIT: the full run of lined friction plates for the clutch packs in a diesel 6R140, built for units from the April 2014 build date on. If you were searching for 6R140 clutches rather than a drum, you are in the right place.
It is frictions only. Steels, seals, pistons and drums are not included.
The 6R140 shifts clutch to clutch, so every gear is two packs applied together and every shift is one pack releasing while another applies. The forward clutch holds first through fourth. The direct clutch is applied in third, fifth and reverse. The overdrive clutch holds fourth, fifth and sixth, and the low/reverse clutch holds first, manual low and reverse. On a diesel pulling a trailer, these packs see far more torque than a gas truck, which is why the diesel units carry more plates and why high energy lining matters here.
A slipping 6R140 is not always a burnt clutch. Low line pressure from the pressure control circuit or worn valve body bores can starve a good pack, so read our 6R140 pressure control solenoid guide first. For a squawk or slip at the 3-4 shift, our 6R140 3-4 clutch failure guide walks through the overdrive clutch failure. If the pan holds lining material and a scan tool shows slip in the gears that share one pack, the clutches are done.
This set is for diesel 6R140 transmissions built from April 2014 on, which covers 2015-and-later 6.7L Super Duty trucks. The build date is on the sticker in the driver door jamb. Gas 6R140 units use fewer plates in some packs, so this diesel count will not match a 6.2L or 7.3L gas build. Early 2011-2014 diesel units should use a kit made for that build. Count the plates in each pack of your old unit, or send us your year and VIN, before ordering. For the full range of parts see the 6R140 parts page.

No. Despite the listing title, this is a BorgWarner 35725KIT high energy friction clutch set for the 6R140. It contains friction plates only.
It is made for diesel 6R140 units built from April 2014 on. Gas units use fewer plates in some packs, so the count will not match. Send us your VIN if you are unsure.
The build month and year are printed on the certification sticker in the driver door jamb.
No. Reuse steels only if they are flat and show no heat damage, and pair the set with a rebuild or overhaul kit for seals and gaskets.
Set the clutch clearances, refill with Motorcraft MERCON LV, reset the adaptive tables with a scan tool, and drive through several full shift cycles so the computer relearns fill times.
