Hey Guys, I need more help please

Im still having 80e segment swap issues. I finally have the segment swap process down and no DTC's from the segment swap however I no longer have ABS working. Im using the 2002 auto camaro 12212156 tune file and Ive used both a 2002 Express van and a 2002 silverado 80E file for the trans segment swap. Im getting two codes that Ive never gotten before once I start driving it.

The two codes are:
C0051-Right rear wheel speed
C0245-wheel speed sensor frequency

The car used to be an M6 and Ive swapped to an 80E. Should I go back to an M6 motor tune and then segment swap in the 80E instead of using the 02 camaro auto tune?

Is there something Im doing wrong here? Is anyone else seeing the same issues?

Info on the car is in my sig below.
