If you own a F-150 or Expedition from 2011 to 2017 with a 6R80 transmission, you may encounter a common issue related to the lead frame. The lead frame replaces the internal wiring harness in the transmission and houses essential components such as the output shaft speed sensor, input shaft speed sensor, transmission range sensor, transmission fluid temperature sensor, and wiring for the solenoids.
Failure of the lead frame can cause a range of transmission problems, including erratic shifting, the inability to shift into specific gears, and triggering diagnostic trouble codes such as P0720, P0722, P0731, or P1500. If you are experiencing sporadic shift issues or have any of the mentioned diagnostic trouble codes, the lead frame is likely the culprit.
It’s important to note that some 6R80 transmission models from 2011 to 2013 are covered under an extended coverage recall by Ford due to frequent issues with the lead frame. If you encounter transmission issues, it’s crucial to inspect and, if necessary, replace the lead frame to address the problem without the need for a complete transmission overhaul.
What is the most common issue with the 6r80 transmission?
The most common issue with the 6r80 transmission is related to the lead frame, which takes the place of the internal wiring harness in the transmission. This issue has been observed in the F-150s Expeditions from 2011 to 2017.
What components are affected by the lead frame issue?
The lead frame issue impacts the output shaft speed sensor, input shaft speed sensor, transmission range sensor, transmission fluid temperature sensor, and the wiring for the solenoid, which affects the transmission’s shift behavior.
Are there any recalls or extended coverage for this issue?
Yes, there is a recall and extended coverage for the lead frame issue in certain year models (2011 to 2013) due to the high number of issues experienced. Ford has put out an extended coverage recall to address this issue.
What are the possible symptoms of the lead frame issue?
If the lead frame is faulty, the transmission can exhibit erratic behavior such as difficulty in shifting, being stuck in particular gears, or triggering specific error codes like P0720, P0722, P0731, or P1500. If experiencing sporadic shift issues, the lead frame should be considered as a potential cause.
How can I identify if the lead frame is the cause of transmission issues?
If specific error codes (P0720, P0722, P0731, or P1500) are present, or the transmission is exhibiting sporadic shift issues, the lead frame may be the likely culprit. It is important to ensure that the correct part is replaced to address the issue without needing a complete overhaul of the transmission.
