Replacement lead frame for the Ford 6R80 in 2010-2020 F-150, Mustang, Expedition and Transit. Fixes P0717/P0720 speed sensor codes and harsh shifts.
A 6R80 that suddenly loses its speedometer, sets P0717, P0720 or P0722, or refuses to shift past one gear is very often telling you the conductor plate has failed. This replacement plate, also called the lead frame, comes with the valve body module connector and the case connector seal. It replaces Dorman 926-149 and Ford AL3Z-7G276-A, -B and -D, with the connector matching 6L2Z-7G276-AA and the seal matching AL3Z-7F401-A, for F-150, Mustang, Expedition, Navigator, Transit and 6R80 Super Duty owners who want the electrical fix without paying for parts they already have.
Ford's engine computer runs the 6R80, and it needs two numbers above all others to pick a gear: how fast the turbine shaft is spinning and how fast the output shaft is spinning. Both of those speed sensors are built into this plate, along with the range sensor and the fluid temperature sensor, according to ATRA's GEARS write-up on the unit. The plate also carries power to the seven solenoids. Divide turbine speed by output speed and you get the gear ratio; lose either signal and the computer cannot tell whether a shift happened, so it sets a code and drops to failsafe. That is why the fix on these units is the whole plate, not a single sensor.
Pull codes with a scan tool that reads the PCM, then graph turbine and output shaft speed on a drive. A good plate shows both lines moving smoothly with vehicle speed; a bad one shows one line going flat or noisy, often once the fluid is hot. Check the outside connector for bent pins and fluid inside the plug before you drop the pan. Ford's Customer Satisfaction Program 19N01 is a useful roadmap: for 2011-2013 F-150 and 2012-2013 Expedition and Navigator it called for a lead frame when P0720, P0722, P0731 or P1500 were stored, and it told dealers to follow normal diagnosis if those codes were absent. The F-150 shift problems guide covers the code-by-code checks, and owners with a Mustang should read 6R80 Mustang common problems.
Listed fitment: 2010-2020 F-150, 2011-2017 Mustang, 2012-2017 Expedition, 2012-2017 Navigator, 2015-2019 Transit 150/250/350 and 2017-2020 F-250/F-350 Super Duty, all with the 6R80. Many later F-150s use a different transmission, so confirm the case tag reads 6R80 before you buy. It is not a 6R60 or 6R140 part. When in doubt, send us your year and VIN. You can browse every matching part on our 6R80 collection page.
On 2011-2013 F-150 and 2012-2013 Expedition and Navigator models, Ford required the PCM software updates from recalls 19S07 or 19S19, or program 19B05, to be completed before replacing the lead frame. A Ford dealer can confirm with your VIN whether those were done, and it is worth checking first because the same years were covered for sudden downshift concerns.
To do the swap: drain and drop the pan, remove the filter, unplug the solenoids and lower the valve body. There is no separate transmission module to move over on the 6R80, because the PCM handles control. Fit the new plate, seat every solenoid terminal, replace the case connector and its seal, reinstall the valve body with its bolts torqued to spec, and refill with Mercon LV. This kit has no filter, so add the 6R80 filter and pan gasket kit, or buy the lead frame kit that includes the filter. Clear codes and run the transmission drive cycle so shift adapts relearn.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. Ford calls it the molded leadframe, and the aftermarket often calls it a conductor plate. This one replaces 926-149 and Ford AL3Z-7G276-A, -B and -D.
On the 6R80 the turbine and output speed sensors are part of the plate, so the plate is replaced as an assembly.
No. It includes the conductor plate, the valve body module connector and the case connector seal. Add a 6R80 filter and pan gasket kit, or choose the lead frame kit that includes a filter.
The plate does not change your solenoid body, so the solenoid strategy stays the same. Clear codes, reset adaptive learning and complete the transmission drive cycle. On 2011-2013 F-150 and 2012-2013 Expedition and Navigator, make sure the Ford PCM updates from the related recalls are done.
Mercon LV, checked at operating temperature.
