I have a 2012 Ford Fiesta with the transmission problem, let's start doing a diagnosis and it threw the DTC P0805 - Clutch Position Sensor Circuit
We reviewed the harness, connectors, ground and decided to change the complete transmission. We installed it and proceeded to program and the code always reappears. The fault code is erased within 10 seconds of restarting the vehicle. The DTC reappears.

TSB and extended coverage on TCM. I exaggerate, but it's ALWAYS the TCM. At the dealer, we always assume TCM and only continue diag if it's clear that is not the TCM.
Edit: your vehicle says 5-spd, my reference is for DPS6 dual clutch auto.

Swap the clutch motors and see if the fault moves to the other clutch,
