While driving my truck erratically shifts. Iâve gotten multiple indications stating that Elite frame sensor is bad. I have been traveling 70+ miles an hour down the interstate and my rear wheels lock up the transmission drops in the second gear. This is a major safety hazard as it could cause major accidents. While looking through other complaints, this is a major ongoing condition with the 6R 80 transmissions in 2017 Ford F1 50s that has been reported on numerous occasions.
