Flashing OD light, Code PO781
Hello, guys, I'm new to the forum. I have a 2000 Expedition that had the flashing OD light. It is throwing a po781 code(1-2 shift error) from the transmission. Shifting seems to be fine 1-2-3-OD but seems a little rough/stronger. No slipping. Can anyone give me any info or if they had this problem also?
I had the GEM, mystery blower turn-on issue a month ago after a big snow, but has since gone away. Flashing OD light started a week ago.
Any information on possible causes would be greatly appreciated. Thanks!

Not likely. It's more apt to be the torque converter issue, a shift solenoid, or a servo inside the tranny.
