Two months ago my 2014 Ford Raptor with a 6R80 trans began having issues that pointed to a bad lead frame. I replaced the lead frame and all was well. Fast forward to a week ago. Trans started jumping out of gear then threw a P0979 code. Shift solenoid C control circuit low. I did some research and determined its probably a bad solenoid. I changed all of the solenoids with ones of the same strategy numbers. Still doing the same thing and throwing the same code. Could i have a bad lead frame or is the problem elsewhere?

 

did you figure it out? yesterday i drove my 12 raptor really hard after starting it then all the sudden the trans started shifting extremely weird. thought i blew it but i have the same code.
