Replaces the 926-149 lead frame on Ford 6R80 transmissions, with case connector, valve body seal, filter and pan gasket for a one-pan-drop repair.
This is the budget way to do a complete 6R80 lead frame job in one pan drop. It pairs a lead frame that matches 926-149 and Ford AL3Z-7G276-A, -B and -D with the three items that usually cause a comeback when they are reused: the round case pass-through connector (6L2Z-7G276-AA), the valve body seal (AL3Z-7F401-A) and a filter with pan gasket (FT-188, BL3Z-7A098-A). It suits F-150, Expedition, Navigator, Mustang, Transit and 6.2L Super Duty owners chasing speed sensor codes, a wrench light, or fluid dripping from the connector on the side of the case.
Inside the 6R80, the lead frame is the plastic conductor plate fastened to the valve body. Power and ground for the solenoids run through it from the case connector, and it holds the turbine speed, output speed, range and fluid temperature sensors that report back to the powertrain control module. Note that the module itself is not inside the transmission; on the 6R80 the PCM does the shifting, so this part is wiring and sensors only. When a trace or sensor in the frame fails, the PCM loses a signal it needs and responds with codes and a failsafe gear.
Check the connector first. Unplug the harness at the case, look for fluid inside the plug or green corrosion on the pins, and repair what you find, because fluid wicking into the harness can mimic a lead frame fault. Then watch the speed sensor PIDs on a scan tool while driving: a dead or dropping signal with clean wiring is the lead frame. If the codes are pressure or ratio codes with good sensor signals, the valve body or solenoids are the more likely cause, and the 6R80 valve body wear guide and 6R80 shift problems diagnosis cover those tests.
Listed fitment is the Ford 6R80 in 2010-2020 F-150, 2017-2020 F-250 and F-350 Super Duty, 2011-2017 Mustang, 2015-2019 Transit, and 2012-2017 Expedition and Navigator. Confirm the vehicle has the 6R80, then compare the number on your old frame with 926-149 or AL3Z-7G276-A/B/D. When in doubt, send your year, model and VIN before ordering. More parts for this transmission are on our 6R80 collection page.
Drain the pan, remove the filter and unplug the internal connector, then pull the main control. Remove the six long bolts and lift the frame off. When you move the solenoids to the new frame, keep them matched to your transmission: Transmission Digest notes that Shift Solenoid E changed from a 10.5 ohm design with a tan snout to an 18 ohm design with a gray snout for transmissions built after November 3, 2010, and the two are not interchangeable. Seat the frame with the range sensor pin in the manual valve and torque the six bolts to 53 lb-in in sequence. Install the new case connector and valve body seal, reinstall the main control, then fit the new filter and gasket. Fill with Motorcraft Mercon LV, check level at operating temperature, clear codes and relearn adaptives.
A lead frame swap on its own does not involve flashing the PCM. Programming does come into play if you replace the solenoids or the whole valve body, because the PCM needs the solenoid strategy that matches the new parts. If your old solenoids are worn, a 6R80 solenoid kit installs on this same teardown; just plan on loading the matching strategy afterward. Our 6R80 valve body testing guide explains how to tell when that is worth doing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 6R80 is controlled by the powertrain control module, not a module inside the transmission. Ford's leadframe replacement procedure has no programming step; clear codes and relearn adaptives after the install.
Yes. The round case pass-through connector (6L2Z-7G276-AA) is in the kit, along with the valve body seal, filter and pan gasket, so the leak and the lead frame are fixed on the same pan drop.
Yes, if they were shifting well. Keep the same solenoids in the same positions; Shift Solenoid E comes in 10.5 ohm and 18 ohm versions that are not interchangeable, so do not mix in a used one from another unit.
Mercon LV is the specified fluid for the 6R80. Fill, start the engine, cycle through the gears and check the level at operating temperature.
Speed sensor codes such as P0715, P0717, P0720, P0721 and P0722, along with the wrench light and high gear starts that go with them. Pressure control or ratio codes with good speed signals usually point to the valve body or solenoids instead.
