you could just disable the code, in the dtc section? it says pin 44 on the computer is for reverse lock out, just go get a connecter from gm for 13 dollars, then run one end of the wire to a 12 volt ignition wire, then the other to pin 44, you will have to just move a wire to that spot, you can use any from that 4l60e harness you are not using anymore,
