Blinking OD Light E40D
Just recently I've been having an issue with my OD light blinking and throwing me out of OD when I'm cruising down the highway. When it does this and I come to a stop, its almost like it failed to downshift or the shift points are just all messed up... If you turn the key off and restart, everything is fine. And then today, when I was driving through town, the TC started slipping and I lost all power, but if I shifted into "2" manually, it would drive just fine. This case, there was no OD light blinking.
Has anyone ever heard of anything like this? I've had it scanned at the parts stores and they couldn't read any code. Does anyone suggest a scanner that can also read tranny codes? Any help would be appreciated. I'm leaning towards something electrical, but an not sure yet.
Thank you!

Is the speed gauge jumping around? If yes, might need to clean VSS on the rear differential or replace. It will cause this issue.
There is also a sensor on the trans that will cause this issue.
Codes will better tell you what is wrong though and is the best way to go if all possible.

This poster most likely has a wiring issue . Shutting off the key most likely doesn't clean the VSS temporarily

Differentials dont have filters in them, they have galleys for the .... extra's to fall into. Sometimes they make it to a magnet and stick there.
But depending on how much you got in there, you're damn right, could be a far worse issue. I've found some sorta metal flake in the little galley on every rear end i've opened. Granted, you've worked on far more than me, but when i'm 15/15 on this. I just believe it at this point. But I"m talking a few little flakes, not more than that.
