Replacement 6R80 lead frame with a new valve body seal for 2010-2020 F-150, Mustang and Expedition setting P0720, P0722 or P0776 speed sensor codes.
A 6R80-equipped F-150, Mustang, Expedition, Navigator, or Transit that throws a wrench or malfunction lamp, drops the speedometer to zero with dashes on the odometer, or stores P0720, P0722, P0717, P0731, or P0776 almost always has a problem with the lead frame, not a bad sensor you can buy on its own. This unit replaces OE AL3Z-7G276-D, AL3Z-7G276-B, AL3Z7G276A, and AL3P7G276AG, and it ships with a fresh valve body seal already included so you are not stuck ordering a second part for the same job.
The lead frame, also called the conductor plate, is the molded component bolted to the top of the valve body. It carries the wiring traces between the transmission control module and every shift solenoid, and it physically houses the input shaft speed sensor, output shaft speed sensor, and transmission range sensor. Ford does not sell these sensors as separate parts on the 6R80 - they are built into the lead frame itself, which is exactly why a failing sensor circuit means replacing the whole lead frame rather than a single sensor.
Ford's own Technical Service Bulletin 13-6-8 documents this exact pattern on certain 6R80-equipped trucks built on or before April 8, 2013 - the wrench light, zero speedometer, dashed odometer, and a transmission that engages in a high gear from a stop - and the corrective action in that bulletin is replacing the molded lead frame on the main control assembly. Ford's bulletin specifically notes that the shift solenoids do not need to be replaced for this repair, which is why this listing lets you transfer your existing solenoids onto the new lead frame.
Before assuming the lead frame itself has failed, check the external connector and wiring harness for corrosion or a loose pin, since a bad connection can mimic the same codes. If the connector and wiring check out, pull up the output shaft speed sensor, input speed sensor, and range sensor PIDs on a scan tool - a lead frame with failed internal traces will show a sensor reading stuck, erratic, or missing entirely. Our 6R80 valve body problems and testing guide and 6R80 pressure control solenoid symptoms guide cover the same connector and solenoid checks that rule out the valve body itself before you replace the lead frame on top of it.
This lead frame fits the Ford 6R80 across 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. Ford's TSB 13-6-8 specifically documents this failure on 2011-2014 Mustang, 2011-2013 F-150, and 2012-2013 Expedition and Navigator units built before the April 2013 cutoff, and a separate Customer Satisfaction Program extended the lead frame's warranty on some of those same trucks - check with a dealer using your VIN for any remaining coverage before you pay for the part yourself. Outside that specific window, match your OE part number against the ones this unit replaces, or send your year, vehicle, and VIN and we will confirm fitment. See our 6R80 parts page for the rest of this transmission's valve body and solenoid parts.
Drop the pan and filter, unplug the external connector, and pull the valve body out of the case. The lead frame lifts off the valve body once the solenoid retaining clips and bolts are removed - transfer your solenoids over, since the speed sensors and range sensor are built into the new lead frame and do not need to be swapped. Install the included valve body seal, the round pass-through connector seal that commonly weeps once it has been disturbed, then torque the valve body bolts back in sequence. Refill with Mercon LV ATF, the fluid Ford specifies for the 6R80, and run a level check at operating temperature. Clear the stored codes and confirm the input speed, output speed, and range sensor PIDs read correctly on a scan tool before the road test. If the solenoids you are transferring are old or already intermittent, replacing them at the same time avoids a second teardown, and a fresh transmission cooler is worth adding if the fluid that came out was already dark.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
On the 6R80, the output speed sensor, input speed sensor, and range sensor are built into the lead frame and are not sold separately. If one of those sensor circuits has failed, the lead frame is the part that needs to be replaced.
No. Ford's Technical Service Bulletin 13-6-8 for this exact failure specifically notes that shift solenoid replacement is not required. Transfer your existing solenoids onto the new lead frame during the install.
P0720 (output speed sensor), P0722 (no output speed signal), P0717 (input speed), P0731 (1st gear ratio), and P0776 (pressure control solenoid B) are all codes tied to sensors and solenoid wiring built into the lead frame.
It ships with a fresh valve body seal included, the round pass-through connector seal that commonly weeps once disturbed, so you are not ordering a second part for the same job.
Mercon LV ATF is the fluid Ford specifies for the 6R80. Refill with Mercon LV and check the level at operating temperature before the road test.
Ford ran a Customer Satisfaction Program extending lead frame coverage on some 2011-2013 F-150 and 2012-2013 Expedition/Navigator trucks. Check your VIN with a Ford dealer for remaining coverage before paying for the part yourself.
