6R80 Overhaul Kit 2015, new and ready to install. Fits the 6R80. Ships fast from the USA.
This overhaul kit is for the late 6R80, the 2015-and-later six-speed behind the aluminum-body F-150, the 2015-2017 Mustang and the EcoBoost Expedition and Navigator. If your truck drips from the pan or case connector, takes a second to drop into gear on a cold morning, or has started to slip on a high-mileage rebuild candidate, this is the seal and gasket set the rebuild starts with. The kit ships as either a Toledo or a Precision International overhaul kit, depending on stock at the time of order, and both are built for the 2015-up 6R80.
The 6R80 builds its six ratios from five clutch packs, A through E, and every forward gear needs two of them applied at once. Each pack is held by a rubber piston seal and fed through sealing rings that carry oil across rotating parts. When those rings and seals harden, a pack fills slowly or loses apply pressure under torque, and the transmission computer logs it as a ratio problem. This kit renews the hydraulic sealing in one pass: the full paper gasket set, the rubber seal set, O-rings for every position, the sealing rings and the snap rings. It does not include frictions, steels, pistons, a filter or a converter, so budget for those if the packs are burnt.
The 2015-2017 F-150 has two well-documented faults that look mechanical and are not. Ford recall 26S28 (NHTSA 26V-237) covers lead frame and range sensor signal degradation that can cause an unexpected 6-2 downshift, and bulletin 20-2060 covers an intermittent neutral when shifting into Reverse with no codes, fixed by a PCM reprogram. Check both with a dealer first. Our F-150 shift problems guide walks through the scan-tool checks, and the 6R80 common problems guide lists every recall and bulletin. If the electrical side and software are clean and the unit still leaks or slips, it is time for seals.
The kit is built for the 6R80 from 2015 on. That covers the 2015-2017 F-150 (and the 3.3L V6 F-150 through 2020, which kept the 6R80), the 2015-2017 Mustang, the 2015-2017 Expedition and Navigator with the 3.5L EcoBoost, and the 6R80 Transit. The front-wheel-drive Edge, Explorer, MKX and MKT use a different transmission, so this kit does not fit them. Ford kept making running changes inside the 6R80 well into 2014 and 2015, so a 2009-2014 kit is not a safe substitute. For those earlier units use our 2009-2014 6R80 overhaul kit. Read the tag on the case or send us your year, model and VIN, and browse the rest of the family on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the sealing kit: paper gaskets, rubber seals, O-rings, sealing rings and snap rings. Frictions, steels, pistons, the filter and the converter are not included. If the clutch packs are burnt, you need those parts as well.
Yes, if the truck has the 6R80. The 2015-2017 F-150 used the 6R80, and the 3.3L V6 kept it through 2020. Other 2018-and-later F-150 engines moved to the 10R80, which this kit does not fit. Send your VIN if you are not sure.
No. Those are front-wheel-drive based and use a different six-speed transaxle. This kit is only for the rear-wheel-drive 6R80.
Mercon LV. Ford lists Mercon LV for every 6R80 application and advises against supplemental additives.
Probably not by itself. Ford bulletin 20-2060 covers that condition on 2015-2017 F-150s with no codes and the fix is a PCM reprogram and adaptive relearn. Have that done before you tear the unit down.
Yes. Reset the transmission adaptives with a scan tool and drive the relearn cycle so the computer learns the new clutch fill times.
