10R80 Expedition Common Problems and Fixes

Every Expedition and Navigator since the 2018 redesign has a 10R80 behind the 3.5L EcoBoost. That is the same 10-speed Ford puts in the F-150, and most of the same bulletins cover both. The Expedition still has its own way of failing, though. It is a heavier vehicle that tows a lot and spends years as a family hauler. More of them have park-by-wire and the rotary shift dial. And the separator plate part numbers change with the shifter. Our 10R80 common problems guide covers the transmission family. This one sticks to the Expedition.

Before anything else, get two facts off the door tag: the model year and the build date. Ford splits its Expedition bulletins at 15-Aug-2022 and 23-Sep-2024, and the big 2026 park recall uses its own build window. Everything below comes from Ford's service bulletins, NHTSA recall filings and Sonnax. The links are at the bottom.

Expedition 10R80 bulletin and recall map

Find the vehicle in this table before you pick up a wrench.

The shift-quality bulletins all list the same codes: P0751 through P0772 (shift solenoids A through F), P2700 through P2708 (friction element apply time), P0729 and P0731 through P0736 (gear ratio), plus P076F, P07D9, P07F6 and P07F7. They tell you a clutch did not apply when the TCM expected it to. They do not tell you why. On an Expedition the build date usually does.

Know which shifter it has

The 2018-up Expedition came with two shift systems. Most have the rotary dial on the console, which is park-by-wire. Column-shift vehicles, which include the police-package Special Service Vehicle, use a mechanical cable. This matters more on the Expedition than on any other 10R80 application, for three reasons:

• Different separator plates. TSB 23-2152 lists JL1Z-7Z490-C for an Expedition with the rotary dial (and the Navigator), and JL3Z-7Z490-E for an Expedition with column shift. If you order the plate for the wrong shifter, the valve body overhaul is wrong before it starts.
• Different recalls. Recall 18V-214, the unseated shift cable clip on 2018 vehicles, specifically excludes Expeditions with the rotary dial. Recall 20V-197 caught the same clip on 2020 police-package Expeditions. The 2026 park pawl recall is the reverse. It only covers park-by-wire vehicles.
• Different removal parts. When the transmission comes out, Ford's bulletins call for a new park override lever bolt (JL1Z-7N134-A) on non-column-shift Expeditions.

2018-2021: adaptives first, valve body second

TSB 23-2152 (May 2023) covers 2018-2021 Expedition and Navigator. It names two causes for harsh engagement and harsh or delayed shifts: bad adaptive data in keep alive memory, or the main control valve body. The repair splits the same way. Reprogram the transmission strategy and run the adaptive learning drive cycle. If the shifts are still bad, overhaul the valve body and relearn again. Ford pays 4.6 hours for an Expedition valve body overhaul alone, and 5.3 hours for the reprogram plus the overhaul. If the valve body comes off, the bulletin calls for new shift solenoid retaining clips (HL3Z-7G007-A).

On these vehicles I always check the batteries first. An Expedition that sits for long stretches, or one with a pile of aftermarket electronics, can lose keep alive memory or adapt badly on a weak battery. It then drives exactly like a bad valve body. Load test, clear codes, set the fluid level hot, update the software and do the full drive-cycle relearn. Only then decide whether it needs a valve body. A good share of these never get past the relearn.

2022 built on or before 15-Aug-2022: prove the CDF leak

The 2022 redesign year has its own bulletin. TSB 24-2304 says 2022 Expedition and Navigator built on or before 15-Aug-2022 can throw the same code list because the sleeve in the CDF clutch cylinder (7H351) moves axially. That opens a leak in the circuit feeding the clutches. The commanded clutch fills slowly or loses pressure, and you get a flare or a slow engagement before the ratio and apply-time codes set.

Ford does not let you condemn the cylinder on symptoms. The test is a line pressure check with a transducer on the M10x1.0 line pressure port. Use an M10x1.0 to 1/8 in. FNPT adapter, because Ford warns that an NPT fitting will damage the case. Then:

1. Monitor LINEDSD, RPM_DSD, the shift solenoid current PIDs SSA_AMP through SSF_AMP, TR_Corrected and TFT on a bidirectional scan tool.
2. In Park with the parking brake set and TFT at 50 C (122 F) or higher, command all six shift solenoids to 0 mA. Hold engine speed at 500-600 rpm and command line pressure to 1900-2000 kPa (275-290 psi).
3. Command SSA to 1.0 A for two seconds, then back to 0 mA. Repeat with SSC.
4. Compare pressure before and during each apply. A circuit that sags when its clutch is commanded on is leaking.

The labor times show why the test comes first. A passed test pays 0.8 hours and the transmission stays in. A failed test means the transmission comes out for a new CDF cylinder: 11.4 hours on a 2022 Expedition 4x2 and 12.4 hours on a 4x4. On a 4x4 Expedition the removal parts list also includes new CV joint-to-transfer case flange bolts and retaining straps (7L1Z-4B496-D).

Built 16-Aug-2022 through 23-Sep-2024: the F clutch

Expeditions built from 16-Aug-2022 on got the upgraded CDF cylinder, and TSB 26-2408 (the 16 September 2026 update that superseded 26-2241 and 26-2309) says they do not need one. They have a different failure. Through 23-Sep-2024, the F clutch friction plates can brinell into the clutch and planetary container cylinder (7B177). In plain terms, the plates dent the container, so the F clutch hangs instead of applying and releasing cleanly. The driver feels it as harsh 3-4 and 4-5 upshifts, harsh 5-3 and 4-3 downshifts and harsh reverse engagement, usually worst on a cold morning.

Diagnosis starts at the pan. Drop it, pull the filter and look at its top side. Gray silt means the bulletin applies. A clean filter sends you back to normal diagnosis. The inspection pays 2.2 hours on an Expedition. A failed inspection means overhauling the valve body and replacing the F clutch plates and the 7B177 container: 10.4 hours on a 4x2 and 11.6 hours on a 4x4. F clutch clearance is set with a selective snap ring, and the job replaces the input shaft, sun gear shaft and front support seals, so have a seal kit on the bench. The bulletin lists separator plate L1MZ-7Z490-M for the F-150, Expedition and Navigator, and the non-hybrid filter HL3Z-7A098-A.

The 2026 park pawl recall

This is the newest Expedition issue and the one owners will ask about. Recall 26V-402 (Ford 26S48), filed in June 2026, covers 246,202 2018-2021 Expeditions with park-by-wire and the 10R80, built 14-Mar-2017 to 27-Jul-2021. Ford's Part 573 report says the valve body separator plate can limit flow to the park valve. On certain commanded shifts the park pawl then engages for a moment while the vehicle is moving, and that can damage the park system.

The symptoms in the filing are worth knowing: the vehicle moves after being shifted to Park, will not go into Park, or gets stuck in Park. There is also a wrench light in the cluster, and the electric parking brake applies automatically if the range sensor does not reach Park. As of May 2026 Ford counted 62 reports and 3 NHTSA complaints on 2018-2021 Expedition and Navigator. The remedy is a PCM software update (Expedition/Navigator PCM software JL7A-14C204-*), plus an inspection of the park system and replacement of damaged parts. The remedy was not yet available when the recall was filed. Owner remedy letters are expected in phases through the second quarter of 2027.

For a shop this means one thing. If a 2018-2021 rotary-dial Expedition comes in with a Park complaint, run the VIN through NHTSA's recall lookup before you quote anything. Do not tear into a park system Ford is going to fix for free. Tell the owner to use the parking brake every time until the remedy is done.

Related: the momentary neutral-out bulletin

The park circuit has a second, older paper trail. Ford TSB 23-2120 (15 May 2023, superseding 22-2145) covers 2018-2021 Expedition and Navigator with the 10R80 built on or before 29-Apr-2021 that show a momentary neutral-out while in Drive, sometimes with DTC P07E6 and/or P07E4 and an audible noise. Ford traces it to a leak in the park valve circuit. The repair is internal: inspect the park system hardware for wear or damage and install an improved valve body separator plate, JL1Z-7Z490-C for the Expedition/Navigator 10R80, along with park pawl, return spring, shaft and actuator rod parts as needed. If a truck in that build window drops into neutral for a split second on the highway, check this bulletin and the 26V-402 recall together before you diagnose clutches.

Fluid and level on a vehicle that tows

Ford special service message 47093 told dealers that 2018 Expedition and Navigator 10R80s take MERCON ULV, Motorcraft XT-12-QULV (WSS-M2C949-A), and that the wrong fluid can cause internal damage. Set the level hot, not by quart count. Sonnax gives normal operating temperature as 96-101 C (206-215 F), and it found that as little as one quart overfilled causes overheating and venting out the breather. A towing Expedition already runs hot, so an overfilled one vents faster. That fluid on the case looks like a seal leak when it is not. Our 10R80 fluid type and capacity guide has the fill details.

How I triage an Expedition 10R80

1. Door tag and shifter. Model year, build date, and rotary dial or column shift.
2. Recall lookup. Check 26V-402 on park-by-wire 2018-2021 vehicles, and the 2018 cable and roll pin recalls.
3. Batteries and codes. Load test and scan all modules.
4. Hot fluid level. MERCON ULV only, set at 206-215 F.
5. Software and relearn. Before any hard parts on 2018-2021 vehicles.
6. Prove it. On a 2022 built by 15-Aug-2022, run the CDF pressure test. On a vehicle built 16-Aug-2022 through 23-Sep-2024, pull the filter and look for gray silt.
7. Order by shifter. Get the separator plate and removal parts that match the shift system.

FAQ

What transmission is in the Ford Expedition?

Every 2018-and-later Expedition and Navigator uses the Ford 10R80 10-speed automatic behind the 3.5L EcoBoost. It is the same transmission family as the F-150, and most Ford 10R80 bulletins cover both, but the Expedition uses its own separator plates depending on whether it has the rotary shift dial or column shift.

Is there a recall on the Expedition 10R80 transmission?

Yes. Recall 26V-402 (Ford 26S48), filed in June 2026, covers 246,202 2018-2021 Expeditions with park-by-wire built 14-Mar-2017 to 27-Jul-2021. The park pawl can briefly engage while moving, and the remedy is a PCM software update plus inspection and replacement of damaged park parts. 2018 vehicles also had recalls 18V-213 and 18V-214.

Why does my 2023 Expedition shift hard from 4th to 3rd when cold?

Ford TSB 26-2408, the current version of 26-2241, covers harsh 3-4 and 4-5 upshifts, harsh 5-3 and 4-3 downshifts and harsh reverse, worse when cold, on Expeditions built 16-Aug-2022 through 23-Sep-2024. The F clutch plates brinell into the 7B177 container. Gray silt on top of the filter confirms it, and the fix is an F clutch and container replacement, not a relearn.

What TSB covers harsh shifting on a 2018-2021 Expedition?

TSB 23-2152 covers 2018-2021 Expedition and Navigator with harsh engagement or harsh and delayed shifts. Ford's repair is a software reprogram and adaptive relearn first, then a main control valve body overhaul if the shifts are still bad. The separator plate differs by shifter: JL1Z-7Z490-C for rotary dial and JL3Z-7Z490-E for column shift.

What fluid does an Expedition 10R80 use?

MERCON ULV, Motorcraft XT-12-QULV (WSS-M2C949-A), per Ford special service message 47093. Set the level hot at 206-215 F on level ground, because Sonnax found as little as one quart overfilled causes overheating and venting.
