10R80 Tcc Solenoid, new and ready to install. Fits the 10R80. Ships fast from the USA.
Ford's 10-speed is smooth when the converter clutch is doing its job, so the first sign of trouble is usually a vibration at steady speed that was never there before, or a tach needle that drifts up and down on a flat highway. This is a new Motorcraft torque converter clutch (TCC) solenoid for the 10R80, the transmission behind the F-150 since 2017 and the Expedition, Navigator and Mustang since 2018, with the Ranger joining for 2019.
The 10R80 does not simply lock the converter at one speed and leave it there. The module manages a small, controlled amount of converter slip in many gears to smooth out driveline vibration, and the TCC solenoid is how it does that. It is a variable force solenoid that works in proportion to current: no current gives no pressure, and more current gives more. Transmission Digest identifies it as the normally low solenoid on the main control, the opposite of the normally high line pressure solenoid beside it. Its signal pressure moves the TCC regulator valve, which in turn feeds the converter clutch. GEARS adds that the module never drops the current fully to zero, even when it commands the solenoid off, because it keeps a small idle current flowing to monitor the circuit.
The solenoid is only one link in the lockup chain. Early 10R80s in 2017 and 2018 F-150, Raptor, Expedition, Navigator and Mustang applications had documented trouble with a sticking TCC regulator valve, which GEARS says can cause the same shudder with or without P0741 or P1744. Start with fluid condition and level, then watch converter slip on a scan tool against what the module is commanding. A solenoid that does not respond to command is an electrical or solenoid fault. A command that is steady while slip keeps hunting points at the regulator valve or the converter. Our 10R80 F-150 common problems guide and 10R80 Expedition common problems guide cover how this plays out on each vehicle.
This listing is a general 10R80 TCC solenoid without a narrower year range, so it applies across the 10R80 family: F-150, Expedition, Navigator, Mustang, Ranger and Transit models built with this transmission. It does not fit the Bronco's 10R60 or the 10R140. Because Ford calibrates each 10-speed solenoid and assigns it a band number, GEARS advises that a single replacement solenoid carry the same band number as the one coming out. Read that number off your original before ordering, or send us your year and VIN so we can confirm. If you want a version tied to a specific year range, see the 10R80 TCC solenoid for 2019-2024, or browse the full 10R80 parts catalog.
Plan on removing the pan and main control. Install the solenoid with a new O-ring and make sure the retaining clip sits squarely; Sonnax warns that 10-speed latch valves can be damaged by the solenoid retainer clip, so look at the valves near it while the body is out. Refill with Mercon ULV only and check the level hot. If the converter has been slipping long enough to darken the fluid, flush or replace the cooler, and a 10R80 transmission cooler is available for later trucks. A complete 10R80 solenoid kit is the better choice when more than one solenoid is suspect. Finish by clearing codes, resetting adaptives and driving through repeated lockup cycles at steady speed.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a general 10R80 listing that applies to the F-150, Expedition, Navigator, Mustang, Ranger and 10R80 Transit. It does not fit the Bronco (10R60). Match the band number on your old solenoid, or send us your year and VIN to confirm.
Motorcraft is Ford's own service parts brand, so this is the brand Ford uses for replacement parts. Like any 10R80 solenoid, it still needs to match the band number of the original for the module calibration to be correct.
Yes. GEARS documented sticking TCC regulator valves on 2017-2018 F-150, Raptor, Expedition, Navigator and Mustang models causing erratic lockup and shudder, with or without P0741 or P1744. Inspect that valve whenever the main control is out.
At minimum the solenoid O-ring and fresh Mercon ULV. If the fluid is dark or contaminated, flush or replace the cooler and consider the converter, because a slipping converter clutch contaminates the whole system.
The 10R80 runs a controlled amount of converter slip, and a TCC solenoid that cannot hold steady pressure lets that slip hunt up and down. A worn regulator valve or converter clutch can do the same, so compare commanded versus actual slip on a scan tool.
