Replaces the LC3Z-7G186-A filter and ACM pan gasket on Ford 10R140 ten-speed transmissions during a Super Duty fluid and filter service.
Searching for a replacement for Ford filter LC3Z-7G186-A, or need everything for a 10R140 pan drop on a Super Duty? This kit pairs the internal filter with a molded ACM pan gasket and covers more of the 10R140 lineup than a diesel-only kit: 2020-2024 F-250 and F-350, 2020-2023 F-450, F-550 and F-600, and 2024 F-650 and F-750 medium-duty chassis, whether the truck runs the 6.7L Power Stroke or the 7.3L gas V8.
Ford lists LC3Z-7G186-A as the filter and screen assembly inside the 10R140 pan. It is the only thing between the sump and the pump, so every drop of fluid headed for the clutches, the converter and the valve body goes through it. The ten-speed's shift clutches are applied by direct-acting solenoids that push on clutch control valves with a very short stroke, which makes the hydraulics sensitive to debris in a way older Ford automatics were not. The pan gasket's job is simpler but just as important: the 10R140 pan is large, and a single molded gasket seals the whole rail. The gasket here is ACM rubber, a heat-resistant polymer that holds its shape in hot Mercon ULV and is installed dry.
Look under the truck first. Fluid on the pan flange with a dry case above it points to the gasket; fluid running down from higher up is more likely a cooler line or case connector. For shift complaints, scan the transmission module for codes before you assume it is a service item. A restricted filter can drop line pressure and cause late, flared shifts, but so can a weak solenoid or worn clutch. The high-mileage ten-speed service checklist and our filter and pan service guide cover what to look for in the fluid and on the magnet; the control design is shared across the Ford ten-speed family.
Listed fitment for this kit is Ford F-250 and F-350 Super Duty 2020-2024, F-450, F-550 and F-600 Super Duty 2020-2023, and F-650 and F-750 for 2024, all with the 10R140 ten-speed automatic. Ford has revised the factory pan gasket number over time (the current PC3Z-7F396-A supersedes earlier LC3Z-7F396 versions), so if your pan has been replaced with an aftermarket deep pan, compare the bolt pattern and gasket groove before ordering. If your truck is a 2025 or you are not sure of your build, send us the year and VIN and we will check it. Diesel-only owners can also compare our DF-440 filter kit for the 6.7L.
Have the full amount of Mercon ULV ready before you start; the 10R140 should not be filled with a substitute. Drain and lower the pan, clean the magnet, and wipe the case and pan rails until they are free of old fluid. Pull the old filter, make sure its neck seal did not stay in the case, and press the new filter fully home. Set the ACM gasket into the pan dry with no sealant. Start every bolt by hand, then tighten in a cross pattern to Ford's torque value. Refill and check the level hot with the engine running. If the pan is bent or you want more capacity for towing, the 10R140 deep cast aluminum pan fits during the same job. If you are going into the valve body while the pan is off, the 10R140 8-piece solenoid pack is the matching repair, and the module needs an adaptive reset afterward.

Yes. It is listed as a replacement for LC3Z-7G186-A, also catalogued as FT211, and includes the oil pan gasket so you do not have to source it separately.
Yes. The listed fitment covers 10R140 Super Duty trucks with either the 6.7L diesel or the 7.3L gas engine for the model years shown. For a 2025 truck, send us your VIN so we can confirm before shipping.
Molded rubber gaskets can often be reused if they are undamaged and still seated in the groove, but a new gasket is cheap insurance on a pan this size. Install it dry with no sealant either way.
A pan drop only replaces part of the fluid in a 10R140, because the converter and cooler hold the rest. Buy enough Mercon ULV for the pan plus a margin, then fill to the hot-check level rather than to a fixed number.
Inspect the magnet and the debris first. Clean fluid needs only the filter and gasket. Heavy friction or metal debris, or a history of harsh shifts, points to solenoid or clutch work, which is easier to plan while the pan is already down.
