M and S lights still flash though, and I don't see any dashboard lights from the gearbox, so I suspect there is some communication breakdown there.
Sorry, but I don't understand. Where are the M&S lights flashing, if it's not on the dashboard?
Often the flashing lights is caused by insufficient electrical supply to the transmission ECU on engine start, so the ECU sees aproblemand fires up the warning lights.
As a test you could start the engine,DO NOT TOUCH THE GEAR LEVER, let it tick over whilst you do your seatbelt/check and adjust mirrors etc, before selecting any gears. This slight pause allows the alternator to replace the juice that the starter took from the battery, so feeding more volts to the transmission ECU.
If this works it's a strong indicator that your battery is weak needing an overnight charge or replacement.
