Reman 10R80 Rotary Dial Transmission
This is a remanufactured 10R80 10 speed automatic transmission built for the 2018 Ford Expedition in the floor shift (rotary dial shift) 4x4 configuration. The full industry description reads AT 10 speed 10R80 floor shift rotary dial shift 4x4, and one unit is needed per vehicle. If your Expedition uses the rotary dial selector rather than a column shifter, this is the direct fit assembly you are looking for.
The 10R80 is a 10 speed, rear wheel drive automatic co developed by Ford and GM, though each company tunes the architecture differently. Ford rolled the unit out in the 2018+ Expedition and builds it at the Livonia Transmission Plant in Michigan. The '10' marks the forward gears, 'R' designates the rear biased drive layout, and '80' indicates the approximate torque capacity in Newton meters times ten. Expect confident, smooth operation when correctly matched.
Fitment And Shift Type Distinction
This unit fits the 2018 to 2020 Ford Expedition as an automatic, 10 speed, 10R80 with floor shift (rotary dial shift) in the 4x4 drivetrain. Replacement units also fit select 2018 to 2021 Expeditions with a 3.5L and conventional shifter. It does not fit Raptor or ROUSH models, so confirm your exact trim and build before ordering to avoid an installation mismatch.
The shift type distinction is critical. The 2018 Expedition was offered in both column shift and floor shift (rotary dial) configurations, and these are not interchangeable. This product matches the floor shift rotary dial shift 4x4 variant specifically. The 2021 Expedition used an updated rotary dial variant without the 10R80 listed separately, so match your model year, selector style, and drive layout precisely.
The 10R80 family is shared across many Ford vehicles, including the 2017+ F-150, 2018+ Mustang GT, 2018+ Expedition and Lincoln Navigator, 2019+ Ranger, and 2021+ Bronco. While the hardware is related, calibration and pairing differ by platform. For your Expedition, verify compatibility using your VIN and transmission code so the TCM and ECM pairing lines up correctly with this unit.
What Is Included
Every transmission we ship comes complete with the torque converter installed. The slim 260mm converter sits inside the built in bell housing, and the converter carries a turbine damper with a 1.82:1 stall ratio. You get a ready to install assembly rather than a bare core, which saves you sourcing and matching those components separately during the job.
This assembly includes the bell housing, the tail housing, and the torque converter. It does not include the transfer case assembly or the flex plate. Since this is the 4x4 variant, plan to transfer your existing transfer case or source one separately. Keeping these items clear up front prevents surprises once your installer has the Expedition on the lift.
The 10R80 is built entirely of aluminum with no cast iron parts, including an aluminum stator support that trims weight. Internally it uses four simple planetary gearsets, all helical gears, four internal speed sensors, and a space saving triple clutch assembly with six clutches total, two brake and four rotating. Weight with fluid runs about 234 pounds in the 4x4 form.
Performance is where this 10 speed shines. It features a low 4.696 first gear for strong off the line launch and a wide 7.39 overall ratio spread, yet the steps between gears stay extremely small. Three of the ten speeds are overdrive ratios, and the lower numerical top gear drops highway RPM for better efficiency. Engine speed falls roughly 20 percent with each shift, keeping the engine in its ideal range much like a CVT, maximizing power under acceleration and economy at cruise.
The electronics do a lot of the work. The 10R80 learns your driving habits through adaptive software and adjusts shift timing for performance or economy, while the ECU manages converter lock up, downshifting, and torque management. Three driving modes, Tow Haul, Sport, and Normal, each reshape the shift schedule for the task at hand. An integrated electric fluid pump supports the engine start stop feature with minimal delay, and a high speed one way clutch keeps shifts smooth and responsive.
