flashing M & S lights

Hi Guys , and another one for you gentlemen
Drove the disco up to the yard, turned it off, about an hr later got back in and the M&S lights, the "D" in the dash display, and the little red lights either side of the gear selector lever were all flashing.
Pushed the mode button and that did nothing
Didnt seem to have any loss of power, but the truck did seem to hold the gears longer.
when i got home plugged in the nanocom and the faults logged were......

any ideas welcome

I'm no auto box expert, but the flashing M+S lights are usually due to some sort of problem with the XYZ Switch on the gearbox.

Check for oil in the ECU red plug, if it's soaked the CAN signal is affected too
