He he... I tried all of these things during my 100 mile trip back home from SSP last night
Thing is, it only flashes in D. No lights to indicate which gear it is in - in the left row of lights from 1-5..
It did work perfectly as normal though.
I have heard that IF the 4.th gear AND DRIVE light flashes at the same time, then it has gone into limp home mode, and needs a flush + new oil. Luckily, this is not it.
Note that the tranny has been out from the car for 5 days and does need a reset of it cpu.
