Took the car out to get fuel just down the road, on the way back I received a transmission fault on screen, wouldn't move out of 'Drive', and wouldn't exceed 1800rpm.

Once I parked up in the driveway, I received this message:

So I turned the engine off/ on and took the car out for another 15 minute spin and all seemed OK.
1) should I be worried?
2) is there anything I can/ should check?
3) could a recent remap have caused it?
Thanks!
