Complete 8-piece shift solenoid pack for the Ford 10R140 10-speed, the full set that lives in the valve body of 2020-up Super Duty trucks.
If your 2020-or-newer F-250, F-350, F-450 or F-550 Super Duty has started banging into gear, flaring between shifts, dropping into a fail-safe gear, or setting a shift solenoid code, the solenoid bank inside the 10R140 valve body is one of the first places to look. This is the complete 8-piece set for that bank, so the whole group is renewed at once on the 6.2L, 6.7L Power Stroke and 7.3L trucks that use the heavy-duty ten-speed.
The 10R140 shares its control design with the lighter 10R60 and 10R80. Six clutches (A through F) produce the ten forward gears, and each clutch has its own shift solenoid. Ford calls these Casting-Integrated Direct-Acting Solenoids. They are linear force units: an armature and pin push directly on a clutch control valve in the valve body, and no fluid flows through the solenoid itself. Pressure is proportional to current, so zero current means zero apply pressure for that clutch. The other two pieces are the line pressure control solenoid, which works inversely (full pressure with low current), and the torque converter clutch solenoid, which controls converter lockup slip. Six shift solenoids plus line pressure plus converter clutch is the eight-piece set you get here.
Because the pin stroke is very small, anything that moves a solenoid off center hurts shift quality. Rebuild kit suppliers for this unit now include stabilization clip inserts because the factory spring-steel retainers can weaken and let the solenoids shift position.
Pull codes with a scan tool that reads the transmission module, not just the engine. Look at commanded solenoid current against what each shift actually does, and check the harness connector and pins for heat damage or fluid wicking before condemning the solenoids. Also rule out hard-part problems that feel like a solenoid fault: one documented 10R140 case with a firm 7-6 downshift turned out to be a broken A clutch return spring, which Ford has since revised. Our shift solenoid symptoms guide covers the same solenoid family and walks through the electrical checks, and the harsh or delayed shift walkthrough helps separate a solenoid problem from a clutch or pressure problem.
This set is listed for the Ford 10R140 ten-speed in 2020-and-newer F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.2L gas, 6.7L Power Stroke diesel or 7.3L gas engine, and in F-600 chassis where equipped. The 10R140 is not the same unit as the 10R80 in an F-150 or Expedition, even though the controls are similar, so do not cross-shop between them. Pull the pan and compare the connector style and solenoid layout on your valve body to the photos before ordering. If you are unsure, send us the year and VIN and we will check it for you before it ships.
Drop the pan, drain the fluid, and disconnect the internal harness from the valve body. Before removing anything, note the band number printed on each original solenoid and its position. Ford calibrates these solenoids, and the factory guidance is that a single replacement must match the band number of the one it replaces, so record what came out in case a shift needs follow-up. Install each new solenoid with fresh O-rings, seat the retainers fully, and reconnect the harness without stressing the pins. Put a new 10R140 filter and pan gasket kit in while the pan is off, and refill only with Mercon ULV, checking the level hot. If the pan rail or gasket surface is damaged, the 10R140 deep cast aluminum pan is a direct replacement with extra capacity. Finish by resetting transmission adaptive values with a bidirectional scan tool and following the adaptive relearn procedure so the module learns the new solenoids instead of compensating for the old ones.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This set is for the heavy-duty 10R140 in 2020-and-newer F-250 through F-550 Super Duty trucks. The 10R80 in the F-150, Expedition and Mustang uses the same control idea but is a different transmission, so order the 10R80 parts for those vehicles.
The module adapts shift pressure around how every solenoid is performing. Replacing the full bank resets that baseline at once, which is why many shops renew the set when the valve body is already apart. If you only replace one, Ford says the band number must match the original.
Mercon ULV only. Do not top off or refill with Mercon LV or a universal fluid. Check the level with the transmission at operating temperature.
Yes. Clear codes, reset the transmission adaptive values, and drive the relearn cycle. If a valve body or module is replaced as well, the solenoid body strategy has to be programmed into the module with a capable scan tool.
It can. A shift solenoid circuit fault or a solenoid that cannot produce commanded pressure can put the 10R140 in a fail-safe gear. Check the harness and connector first, because a damaged pin causes the same result.
