Now my vehicle has over 150 thousand miles and when I went to the same dealer I was told there wasn’t a recall on this truck .

“while in drive, accelerating to highway speeds or cruising around 30 mph it will downshift and jump to about 4000 PMS's and not shift up into 3rd gear. It blown 1 engine and I have replaced the transmissions, taken it to a Ford dealership and they weren't able to help me. I've replaced the ECM and anti-theft modal also and the symptoms still persist. i am i in for over 11K for the new engine and transmission, and another $100 on the ECM and anti-theft modal plus the shop charges. The truck has under 190,000 miles before any of this started. I am the 2nd owner an had for less than 3k miles before any of the problems started. Now I see the 2015-2017 F-150s are having the same problems getting recalled. is there anything involving the earlier Triton's engines?”
