10R60 Overhaul Kit

If your 2020-up Ford Explorer, Lincoln Aviator or 2021-up Bronco has a 10R60 that is coming apart for a rebuild, the soft parts are the first thing on the bench list. This is a Transtec overhaul kit from Freudenberg-NOK, part number 2782, built for the 10R60 and sold without pistons. It is the gasket and seal set that lets every clutch circuit hold pressure again after teardown, whether the job started with a fluid leak, slipping after high mileage, delayed engagement on a cold morning or a harsh shift that sent the unit to the shop.

What the overhaul kit does in a 10R60

The 10R60 is the light-duty member of Ford's 10-speed rear-drive family, rated for 443 lb-ft of input torque. Like the 10R80 it has four planetary gear sets and six clutch packs: four rotating clutches and two brake clutches, all applied by fluid pressure that the valve body sends through sealing rings on the shafts and drums and through the case and front support passages. Every one of those circuits depends on rubber seals, O-rings, sealing rings and gaskets. When they harden or wear, apply pressure bleeds off, the clutch packs slip, and the TCM keeps adding pressure to compensate until the shifts feel harsh or the transmission sets a ratio fault. An overhaul kit replaces those sealing parts in one box. It does not contain frictions or steels, and this version does not include bonded pistons, so inspect your original pistons and reuse them only if the bonded lips are intact.

Most internal parts do not interchange between the 10R60 and the 10R80, so a 10R80 kit is not a substitute here. Our 10R80 vs 10R60 differences guide explains how to tell the two units apart before you order.

Symptoms that call for a reseal or overhaul

• Fluid leaking from the case, pan or cooler line area with no damaged external part to blame
• Slipping or flare between gears at high mileage, especially once the fluid is hot
• Delayed engagement into Drive or Reverse when cold that improves as the unit warms
• Harsh or clunky 1-2 and 2-3 shifts that return after an adaptive relearn
• A harsh 7-6 downshift on early 2020 Explorers and Aviators with the 2.3L, the known A clutch return spring snap ring issue

How to confirm before you buy

Check the fluid level the way Ford specifies: scan tool connected, fluid temperature between 206 and 215 F, level centered in the B area of the indicator. Low fluid alone causes many of the symptoms above. Pull codes and look at the solenoid data, because a bad pressure control solenoid such as the 10R60 pressure control solenoid can mimic worn seals. For the harsh 7-6 downshift, Transmission Digest describes a manual 7-6 test in Selectshift mode; if it confirms the dislodged snap ring, the fix is a new front support assembly, not just seals.

Fitment

This kit is listed for the Ford 10R60 in the 2020-up Ford Explorer and 2021-up Ford Bronco, and the same transmission is used in the 2020-up Lincoln Aviator. Ford has made running changes to the 10-speed, so match the transmission identification tag on the case, or send us your year and VIN before ordering and we will confirm it. Other 10-speed hard parts and shared service items are on the Ford 10-speed collection page, and complete kits for other units are in rebuild kits.

Install notes

• Soak the new seals in Mercon ULV before assembly and use assembly gel on sealing rings so they do not roll or cut going into their bores.
• Air check each clutch circuit with the unit assembled before the valve body goes on. A circuit that leaks down fast points to a cut ring or a scored bore.
• Fill with Mercon ULV only. Other fluids cause shift quality complaints and failure on this family.
• After the rebuild, clear codes and run the adaptive learning drive cycle so the TCM relearns clutch fill.
• If you are already inside the valve body, this is the time to replace the shift solenoids with a 10-speed solenoid kit.

Pick up a filter and fluid with the kit, and plan on frictions and steels if the old clutches are burned or out of clearance.

Does this 10R60 overhaul kit include frictions, steels or pistons?

No. It is the Transtec 2782 gasket and seal kit without pistons. Frictions, steels, pistons and the filter are bought separately if your teardown shows you need them.

Will a 10R80 overhaul kit fit my 10R60?

No. The 10R60 is a smaller, lighter unit and most of its internal parts do not interchange with the 10R80. Order the kit made for the 10R60 and confirm your transmission tag or VIN first.

Which vehicles use the 10R60?

The kit is listed for the 2020-up Ford Explorer and 2021-up Ford Bronco. The 2020-up Lincoln Aviator uses the same transmission. Send us your year and VIN if you are not sure which 10-speed you have.

What fluid goes back in after the rebuild?

Mercon ULV only. Check the level hot, with the fluid between 206 and 215 F on a scan tool, and set it to the center of the B area on the level indicator.

Will new seals fix a harsh 7-6 downshift?

Not on its own. On early 2020 Explorers and Aviators that complaint is traced to the A clutch return spring snap ring dislodging, and the correction is a new front support assembly.

Do I need a relearn after installing the kit?

Yes. Clear codes and run Ford's adaptive learning drive cycle after any rebuild so the TCM relearns clutch fill and shift timing.
