Hello Mick, firstly let me congratulate you on having the longest title ever seen on FOC 🤣

My thoughts would be possible wiring damage to the TCM.

You should down load FORScan (it's free) and get a new 'vLinker FS' lead and then you will be able to check for Ford specific DTC's without the need to go to the main dealer.

I'd remove the connectors from the TCM and take the back Shell covers off and check inside the connector for wiring damage. This can cause intermittent faults and often the DTC is erased when the ignition is turned off.

Longest title I've ever seen on any forum ... and I'm a member of quite a lot of them. Congrats Mick!
