'92 F150 Digital odo gone haywire

"Service"? "Resale"? :sign5: She should get more "service" than she does, but we're not selling her under any circumstances.. when this truck finally gives up the ghost in a non-repairable way, she's welcome to quietly rot away in the front yard until she completely disintegrates- I'm not gonna insult her dignity by sending her to the junkyard to be crushed and recycled like some kind of Hyundai.

No way am I pulling the dash out, no matter what. I was kinda hoping that it would be something like a faulty sensor attached to the tranny, but really I'm not too worried. All the other gauges (analog) function more or less normally.
