I have '13 F150 XLT with the 5.0, and 6R80 transmission. Recently, it started downshifting 6th to 1st on the highway. I found out there was a recall for that, so I took it to a dealer. Their fix was to reprogram the ECM, so it wouldn't downshift, but it didn't stop the wrench from popping up, or the speedometer going crazy. So, I ordered a lead frame off Ebay, replaced the lead frame, fluid, and filter. I was only able to get about six quarts of fluid in before it ran over. Started the engine, and ran back and forth through the gears, but it will not engage in any gear, and won't take any more fluid. I have taken it back apart, and verified everything was correct 3 times now, based on info from about a dozen youtube videos, and everything seems in order, but it does not pull at all. I ran Forscan on it, no codes, it seems to read all solenoids, but shows zero pressure. I am out of Ideas. Anyone else experience this?
