Ok, so some sleepless nights gave me an idea. I was thinking about the transfer case fluid being full if metal. Vss is a magnetic pickup. Picked up metal shaving from the oil. I brake cleaned inside from the top and drained out the bottom. Left it empty (I know) and drove it down the road. Speedometer worked fine for a minute or two then started screwing up again.

The inside of the t case is just all wore out and dirty. Replaced t case. Clean gm autotrac fluid. Good to go. Shifts drives runs ... like new. All a wore out t case that was contaminated with endless metal shaving supply that would confuse the vehicle speed sensor.

I hope it helps someone in the future.
