Question about Toyota Supra
I have the same problem with my 95 Toyota T100. My O/D off light started flashing when my speedometer cable broke this week-end. I assume the electronic transmission is using the speed data to manage the overdrive.
Have your speedometer problem fixed and your flashing light will turn off.

Od off light blinking on my 93 corolla tested as code 42 which is ecm not getting signal from speed sensor. I had my transmission power flushed at ez oil change and after 15 miles of driving the problem was fixed. transmission flush was $107 a new speed sensor is $180. So far I have had no further problems. (4 speed automatic transmission) if problem comes back then change the speed sensor.
