6R80 Ford Lead Frame Problems

A Ford 6R80 lead frame on the ground

The molded lead frame houses the transmission output speed sensor and connects to the shift solenoids on the valve body of your transmission - it is a critical component. We commonly find lead frame issues in the Ford Expedition, Ford F-150, Ford F-250, Ford Mustang, Ford Transit, and Lincoln Navigator. Remember that attempting to fix a transmission when you don’t know what you’re doing can cause more harm than good. Thus, it’s best to hire transmission repair professionals if you’re unsure how to address a possible lead frame issue.

Symptoms That You May Be Having a Lead Frame Issue

  • Vehicle may not start
  • Vehicle may not shift out of Park
  • Vehicle may downshift while driving on the highway / harsh downshifting
  • Vehicle may have Output Speed Sensor, Input Speed Sensor, and/or Range Sensor DTCs (Diagnostic Trouble Codes)
  • Speedometer may not work or only work intermittently

The Importance of Addressing Possible Lead Frame Issues Promptly

At Circle D Transmission, we are familiar with this common issue and only use OEM replacement lead frames. If you’re having problems similar to those listed above, please reach out to us as soon as possible so that we can possibly correct the issue by replacing the lead frame and not the entire transmission. As long as we confirm that the lead frame is the issue and that the transmission pan does not show signs of metal debris, we most likely can be successful in rectifying your transmission’s issues by replacing the lead frame. Never ignore a potential lead frame transmission problem, and never attempt to fix the problem on your own if you’re unsure how to do so. When you address a transmission issue promptly, you may prevent a minor headache from becoming something much more significant.
