Trany fluid looks OK.

Hey, which transmission does your rig have?
I'm not familiar with how OD is handled on anything other than the E4OD, in which overdrive is achieved by a simple electrically-actuated lockup of the torque converter --- does yours get handled the same way?
If indeed your transmission achieves its OD by electric-lockup of the torque converter......then......based on the fact your OD light is blinking....I'm going to throw my hat in the ring and guess torque converter failure. (As was something I think Boywonder also threw out there as a possibility early in this message-board diagnosis session.)
