Hello I have a 2014 fiesta with 240000 miles on it. My transmission will not engage any gears I am getting a po2700 and Po7a2. I can get the engine and transmission from a 2019 with 50000 miles really cheap. Would the ecu/Tcm from the 14 work with the 19 or would I need the 19s ecu/tcm

Only suggestion I could give is going on tasca ford parts or any OEM fords parts store or even the dealer and getting a part number on the 2019 part and on the 2014 part. If the part number is the same then it should be good to go

I have a 2017 engine that originally came hooked up to an automatic transmission in my 2012 manual transmission so it's definitely possible. It's unlikely your ecu went so if I were you I'd keep the one you have, should literally be plug in play for you.
