I have a 2011 f150 that had the normal problems associated with a faulty lead frame, hard shifts, only operating in third gear and throwing a P0720 code. I backed the truck up turned it around and pulled it into my shop and replaced the lead frame, gaskets, transfer tubes, filter and oil. After doing all this the truck will not move in any gear. Removed and reinstalled the valve body and lead frame two more times double checking the installation but ending up with the same result. Will not move in any gear. Thought it may be a bad lead frame so I got another new lead frame and installed it ending up with the same results. No reverse or forward gears. Everything shows up on the dash correct so I know the wires are connected. Fluid level is correct. Any ideas? Thanks.

 

Did you make sure all the connection pins are staying put when installing. Sometimes one will back out on installation and take you for a real ride.

 

We have the same problem with our 2011 f150. Its 2wd with the 6cyl. It used to be a police k9 vehicle. Anywho, initially the problem was intermittent shifting and the dash shift wasnt working at all. So I figured it was some kind of shift or position sensor. replaced the lead frame and absolutely nothing changed. Got another lead frame and now the dash works and reflects the correct gear selection but none of the gears engage at all besides park. Well, I guess I got park and 6 Neutrals haha. Anyone have an idea what's going on here?

Thanks

 

Briefly,,,,
What did you remove to replace the parts?
