I purchased my Ford while it was still under the warranty. I took it to a dealer because I was losing power while driving in a certain gear at a certain rpm after the engine was running for about 30 minutes. I was told it was a wiring issue which I had the dealer fix. By this time I was close to the warranty being up. It didnt fix the issue. The vehicle loses power intermittently or stutters. I get p0352 codes. I have been dealing with it because it is intermittent but recently the wiring harness melted on an ignition coil. I have replaced the ignition coils, the pig tail, the spark plugs, changed transmission fluid, rechecked all the cables, and once the dealer reprogrammed the pcm. It has to be the transmission but because it is intermittent the dealer cant find anything wrong. I actually lost power once at low speeds after the transmission slipped and dinged a poll causing a dent in my car. Thankfully I only lost power once on the high way and no one hit me. Since I am out of warranty I am forced to find the cause and fix it myself. I do not have 4 grand for a new transmission install. My research shows that Ford has three issues with my year. 1. Ignition coils over heating due to bad pcms or programming 2. Transmission bubbles or tears forming in the rings 3. Cable controls on the transmissions. I am out of options and dont know what to do so I figure I would warn off others. Dont by a Ford with the 6f35 transmission unless it is a later year. I hear the 2019 has it fixed and I wish I could have one of those but the best I can do is warn others. I am stuck. 2 years of my life wasted.
