Transmission or sensor?

I have a 99 F250 crew with a 5.4, while driving through town tonight my ABS light came on, spedometer stopped and the RPM's were eratic.

While "limping" it home, it would not shift normal to 3rd, with the eratic rpm's and the spedometer not working, but once it got over 35 mph it would be fine.

My question is do you think this a problem with the tranny or could it be an electrical issue? All fluids are okay...Thanks for any help

It is most likely the vehicle speed sensor on the rear axle. Reading the codes will tell the story.

Just replaced my vss last night very easy job...20 min and 20 bux or so. Does the truck shift hard into first? For me the vss took care of my abs light, the hard shift into first, and the non working speedo.
