10R80 Planetary, new and ready to install. Fits the 10R80. Ships fast from the USA.
A Ford 10-speed that whines with road speed, drops a gear outright, or leaves bright steel on the pan magnet usually has a gearset problem, not a clutch problem. This 10R80 planetary is the hard part you need once the teardown confirms it. The photo shows three pieces: a geared planetary member, a thrust washer, and a separate ring gear with external teeth. This listing carries no year range, so it is the version to look at if your build is anywhere in the 10R80 run and you are matching parts by sight and measurement.
GEARS Magazine lists the 10R80's hardware as four planetary gearsets, six friction clutches and one mechanical one-way clutch. Each gearset is a sun gear, a carrier holding pinion gears, and a ring gear. The clutches lock or hold different members of those four sets, and that combination is what produces ten forward ratios and reverse. Because the sets are tied together, one gearset is loaded in many gears, and damage in one set can affect several ratios. The pinion gears ride on needle bearings and shafts in the carrier, and thrust washers and bearings control end play between each rotating member. When pinion bearings wear, the gears lose their mesh and start to whine. When a spline or tooth lets go, drive through that path is lost.
Start with the pan. Gray silt on the top of the filter on a 2022-2024 truck points to the F clutch problem in Ford TSB 26-2408, where the F clutch frictions brinell into the clutch and planetary container cylinder; that repair is a clutch and cylinder job, not a gearset. Large bright pieces of steel are what point to a planetary. With the unit out, spin each carrier and feel for rough or loose pinions, check pinion end play, and look for chipped teeth or twisted splines. Our 10R80 common problems guide covers the failures that look similar from the driver's seat, and the F-150 common problems guide covers the truck most of these units came out of.
The 10R80 is used in the 2017-up F-150, the 2018-up Expedition, Navigator and Mustang, the 2019-up Ranger and the Transit, but not the Bronco, which uses the 10R60. With four different gearsets inside, the only safe way to order is to match the part in your hand: compare tooth count, spline count, the ring gear's outside teeth and the overall depth against the photo. Ford also revised the 10R80 over the years, so if you have any doubt, send us your year and VIN before ordering. For a year-specific option, see the 10R80 planetary for 2017-2024, or browse everything in the 10R80 collection.
Finish by clearing the adaptive values and running the adaptive learning drive cycle so shift timing matches the rebuilt unit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a geared planetary member, a thrust washer and a separate ring gear. The 10R80 has four planetary gearsets, so compare tooth count, spline count and depth against the part you removed, or send us your year and VIN and we will check it.
Gearset failure tends to show as speed-related whine, a lost gear and bright metal in the pan. Clutch wear shows as slipping, flare and gray or brown friction material. A teardown inspection of pinion end play and teeth confirms it.
Any scored or blued thrust washers and bearings, worn shaft bushings, the filter, and the cooler or a full cooler flush. Most builders also replace frictions and seals, since they ran in the same debris-filled fluid.
No. The Bronco uses the 10R60, not the 10R80. This part is for the 10R80 used in the F-150, Expedition, Navigator, Mustang, Ranger and Transit.
Ford MERCON ULV. Fill to the hot check level and do not overfill, then clear adaptives and complete the adaptive learning drive cycle.
