Peter , On my coach there is a trans module in the front run bay , this is
the elect bay below the driver and there is also one below the shift panel .
Not sure which is which though .
I have read that the trans and engine ECMs are powered by a wire for
each directly from the positive post of the chassis batteries .
Of course yours could be wired to pick up 12v somewhere else but either
way it needs a constant 12v feed for it's memory .
Have you done anything around your batteries recently ?
It has been reported cases of the ECM wires being accidentally left loose,
corroded or finding an in line fuse back there near the batteries .
One case I remember was the wire had a butt connector that had not
been crimped good causing a on and off similar to yours .
This would probably be covered by tape making it hard to find .
Good luck , keep us posted please .
