    OK.

    There is no TCM on these, on 6F15 it's combined with the PCM

    If there's no transmission codes coming up then suspect a mechanical fault with the transmission

    First check battery voltage is spot on, then fluid level correct (warm), then test the main pump is working, then the solenoids and finally the torque converter

    Cheers, instead of that shall I not just replace with a second hand box I know is working.

    You can try, just be aware Focus and EcoSport 125 PS 6F15 is slightly different to Fiesta's 100 PS 6F15.

    Make sure you have the right box.

    I would investigate the fault though, it might just be something daft, unless mileage is sky high

    And ensure you correctly code the replacement's solenoid strategy into the PCM upon installation or it won't work
