Genuine Ford TCM Circuit Board for 6R80 6R140 AL3Z-7G276-D AL3Z-7G276-B

Genuine Ford TCM circuit board for 6R80 and 6R140 six-speed automatic transmissions. Also known as a transmission lead frame, conductor plate, valve-body circuit board, or internal transmission electrical connector. Cross-references OEM numbers AL3Z-7G276-D and AL3Z-7G276-B.

This component is intended for internal transmission and valve-body service when diagnosis identifies a compatible lead-frame or circuit-board concern. The transmission range sensor is integral to the lead-frame assembly on certain 6R80 applications, and Ford’s recall documentation identified intermittent reverse engagement, PRNDL display, backup-light, and rear-camera concerns as possible symptoms in a specific affected 2011–2013 6R80 vehicle population. Those symptoms are not proof that this part will resolve every vehicle concern; proper testing is required.

Fitment And Identification

Match the replacement component to the original lead frame before ordering.

Confirm all of the following:

• Transmission is a Ford 6R80 or 6R140 six-speed automatic.

• Original part number cross-references AL3Z-7G276-D or AL3Z-7G276-B.

• Connector ports, sensor locations, mounting tabs, and circuit-board layout match the removed component.

• Vehicle VIN and transmission application confirm compatibility.

Do not rely on vehicle year, engine size, or model name alone. Published catalog fitment varies by revision, drivetrain, production date, and market. For example, Ford catalog data associates AL3Z-7G276-D with specific 6R80 applications including selected F-150, Mustang, Expedition, Transit, and Lincoln vehicles, but that does not establish universal fitment for every vehicle within those model lines.

Installation Guidance

Professional transmission service is recommended. Installation generally requires transmission pan removal, fluid handling, valve-body access, and careful inspection of internal and external electrical connections.

Before installation:

• Compare the replacement part with the removed lead frame.

• Inspect the transmission case connector, harness, valve body, solenoids, and related connectors.

• Follow the service manual for torque specifications, fluid level procedure, and reassembly.

• Use the manufacturer-specified transmission fluid.

• Perform any required programming, adaptive strategy reset, or relearn procedure.
