Owner Narrative

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?
