I bought a 2011 f150 v6 eco boost back in September it ran awesome like a dream until about 2 months ago when I went to pull out and without warning fell flat on its face it throw out a po715 which said input turbine speed sensor a. It seemed to go away for a while and was fine then it started doing it again whenever I would get around 3,000 rpm’s it would stay in either 3rd gear or 5th which ever one I was in when I hit 3,000 rpm then one day it downshifted straight to 1st from 5th gear I got a new lead frame transmission, tranny fluid, filter, the whole 9 replaced it and it did exactly the same. However it was not a ford OEM lead frame thought maybe it was bad so I got an OEM lead frame and a new solenoid because it was saying speed sensor A was bad or something so I replaced it again whenever I was done nothing it goes into gear but just revs up no in drive reverse everything so I was getting desperate I bought a rebuilt valve body and lead frame solenoids and all took the previous one out put whole new thing in now it’s doing the same thing exactly it’s not throwing any codes out just keeps popping a wrench up on my dash I am lost have no idea what to do seems like I’m screwed. Please somebody help me lol
