Blinking Overdrive Light / P0708

Overdrive light on column shift arm blinking.
First think I did was replace the neutral safety switch on the driver side of the transmission.
Still blinks.
Disconnected battery overnight to reset codes.
Still blinks.
I have driven 200 plus miles since installing the new switch.
The transmission shifts fine, even into overdrive.
I have found a very technical protocol to uncover the problem in the "A" circuit but honestly, most of it is over my head.

Thank you

first thing you need to do is read codes to see what is wrong.
without them, you are just throwing money away.

My OD light blinked , no codes everything functioned correctly.

i replaced the switch on the end of the column shift handle. pops out quite easily.
