Abs and brake light are on . 2005 gmc Sierra 2500 hd 6.0L 4L80E. I changed the vss on the side of the transmission I cleaned both wheel speed sensors I even went as far as changing the ebcm and ran a new ground wire. What else could it be having a p0502 code

If replacing the vehicle speed sensor hasn't solved the issue and the wiring isn't the problem, it's likely the PCM. Here is some more info for you.
