Flashing arrow / 3-1-1 code 900 1992

I just bought a mint 965 to play around with and it has the flashing transmission arrow. I pulled the code from the TCM and got 311 rpm signal missing.
Per the Aw-40 diagnosis manual the speed sensor should ohm out between 400-800 at the tranny connector and the TCM connector. I get around 600 ohms in both spots.
Went to the pick n pull and grabbed a TCM from a 92 (lucky hit). Swapped them out and still no joy? Should I have grabbed the speed sensor? The troubleshooting guide would say its good to go? Anyone have this issue before?
