Transmission delay in shifting and or jerking while shifting through gears. Was travelling at highway speeds in 10 gear and my transmission lost power. Could not accelerate at all transmission was non responsive for a couple seconds while showing it was in 1st gear. This happened a couple more times at lower speeds from 7th gear and downshifted automatically to 1st cutting off any power to transmission. I had made a left turn and vehicle stalled from transmission not accelerating at all and hesitated and jerked into 4th gear. Downshifting and upshifting is delayed affecting the driveability of the vehicle. Vehicle only has 63k miles on it no prior transmission issues at all. I took it into Ford dealership and they said heave seen problems like this with this vehicle in the past and right about where my mileage was at too. Ford says I need a new transmission but cannot diagnose what exactly is wrong with the transmission. Their option they gave me was $6700 to open up transmission and replace parts but the price dsn’t include parts or a new transmission at $8100. In doing a little research online there appears to be a major concern with Ford/GM over the 10 speed 10r80 transmission I have. I have 3 children and do not trust driving the vehicle as the driveability of vehicle is a safety hazard and believe it’s due to Ford knowingly that there are concerns over the transmission and not willing to do anything to fix their engineering issues with the transmission. The highway speed that i explained could have resulted in a crash or worse, someone getting hurt.
