trans is rebuild with the suncoast kit and ml presion tq truck is a 2002 lb7 with a s475 over stock efi live simple 140hp tune. 4x4. i can clear the light but as soon as i do it comes back idk if i messed up the wiring some how pretty simple but never no. couldn't see anymore tonight. the trans before was the stocker that i beat pretty bad. the linkiage wires are hard to get in i was thinking it might be one of those wires if anything could be wrong.

What code(s) would be a big help.

NSBU switch is where I would start. P0380 is not a concern. If your linkage is a notch off, it is bolted on backwards. The ball on the arm needs to be pointed outward.
