My mother in law contacted me and stated her 2014 ford expedition's transmission felt like it was failing. I drove same the next day. As I was test driving the vehicle at approximately 60mph down a U.S. highway, I hear a "clunk" noise and then immediately the RPMs went up and the vehicle downshifted into 1st gear causing the vehicles's wheel to lock up. I went sliding down the highway and luckily didn't not collide with another vehicle. I had the vehicle scanned and same displayed PO722 output speed sensor codes. After further research, I discovered that her transmission is the same model and design as the 6R80 transmissions that were installed from 2011-2017. The 6R80 transmission lead frames were recalled for years 2011-2013 for the exact same safety issue that I encountered. For some reason Ford has done nothing for the 2014 models. This is a huge safety concern. …
