I'm in the same boat as you 100% that I did all steps of wiring properly. Sent pcm to current performance for segment swap. And now I have no speedo, vss code, 1-2 2-3 and tcc pwm codes. And they are absolutely zero help. I had a local guy pull my file. Told me there's a lot of green in the table? He can try to correct it for a hundo. With no guarantee. I'm so po.

the 4l80e I got was apparently swapped from 4wd to RWD. The rear reluctor ring was missing, so no way the rear sensor is going to work. Look in the hole, where the rear sensor goes, there should be reluctor ring teeth close to the center of the hole. If you only see teeth on the very edge of the hole, you're missing the ring. Good chance if you had a blank sensor in there before, just adding a real sensor may not do the trick.
BTW, mine's also missing the tail housing lube hole.
