10R80 Overhaul Kit, new and ready to install. Fits the 10R80. Ships fast from the USA.
If your Ford 10-speed is out of the truck because it slips once it is hot, bangs into gear on a cold start, or drips from the bell housing, this is the soft-parts kit that puts it back together. The 10R80 overhaul kit carries the seal and gasket sets for the whole unit, packaged in factory-style service bags as pictured, so you can reseal the F-150, Expedition, Navigator, Mustang, Transit or Ranger transmission in one order instead of hunting individual Ford service numbers.
The 10R80 makes all ten forward ratios with six multi-plate clutches lettered A through F, and the Ford workshop manual chart shows four of them applied in each gear (third is A, C, D and E; fourth is A, C, D and F). Every one of those clutches is fed oil through a seal. The C, D and F circuits are the tricky ones: Transmission Digest describes them running down a roughly two-foot input shaft and sealing against the sun gear shaft inside the CDF clutch cylinder. Those rotating sealing rings, the piston lip seals, the pump and front support seals and the pan gasket are what this kit replaces. When they harden or wear, oil bleeds off before the clutch is fully applied, the computer stretches its fill time to compensate, and you feel it as flare, slip or a delayed shift.
Note what is not in the box: frictions, steels, bushings and the filter are separate purchases. Look over each pack at teardown and replace what is burnt or worn.
Start with the cheap checks. GEARS Magazine reports that most erratic shift complaints on this unit are cured by a TCM update and the Adaptive Learning Drive Cycle, and a weak battery can make the unit adapt badly. Check the level hot at 96-101 C, because Sonnax found even one quart of overfill makes the 10R80 overheat and vent. If the codes and road test still point inside the case, our 10R80 common problems guide walks through the CDF leakage pattern, and the F-150 shift problems guide covers the truck-specific complaints. Once the unit is apart, a reseal is the baseline job.
This listing is not tied to a single model year. It fits the Ford 10R80 used in the 2017-up F-150 and Transit, 2018-up Expedition, Navigator and Mustang, and 2019-up Ranger. It does not fit the Bronco, which uses the lighter-duty 10R60, or the heavy-duty 10R100 and 10R140. Ford revised internal parts over the production run (its 2026 F clutch bulletin, for example, calls out different service numbers for 2023-2024 Transit and 2024 F-150), so compare the kit against your old parts at teardown, or send us your year and VIN before ordering. If you know your exact year range, the year-specific kits are listed on the 10R80 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. An overhaul kit is the seal and gasket side of the rebuild: piston seals, sealing rings, O-rings and gaskets. Frictions, steels, the filter and any hard parts are bought separately based on what you find at teardown.
No. This kit is for the 10R80 in the F-150, Transit, Expedition, Navigator, Mustang and Ranger. The Bronco uses the smaller 10R60 and the Super Duty uses different 10-speeds.
Motorcraft MERCON ULV only. Set the level hot, at 96-101 C (206-215 F). Sonnax found that as little as one quart over full makes the 10R80 overheat and vent fluid.
Yes. Clear the transmission adaptive values with a scan tool and run the Adaptive Learning Drive Cycle. Without it, the computer applies the worn unit's learned fill times to fresh seals and shift quality suffers.
Not first. Update the TCM software, check the battery and fluid level, and run the relearn. GEARS Magazine reports this cures most erratic shift complaints. Rebuild when slipping, ratio codes or debris in the pan point to internal wear.
