I'm not too sure what to get out of this. I tried to pull codes out of the ECU, but I've never seen an OD OFF light flash as well.

The actual problem is my transmission shifts weird, it doesn't go into OD (4th) unless the OD light is flashing at highway speeds. It feels like all gears are working at some point when I drive, but this has me stumped so far. So i tried to pull codes and both the OD off and CEL start flashing like crazy, but there's no code to be gathered from it.

Here's a video showing what I got so far. Sorry about the lighting issue

Any help would be appreciated!

**Apparently that's the signal for all good, according to my quick research. But my transmission is still having problems. Can I only get the code if the light is flashing while the car is moving??
