So I found this code U1477, does anyone know what could be, I'm thinking is wiring but just in case someone had this problem before, maybe @Jimmy07 can give me some light on this one,
The wiring harness was bad, looks like someone had messed with it as some wires were spliced and taped together, installed a new one and problem solved, very happy with the outcome, tuned the transmission with GDE and they work as manual shifting like intended..
