My 2002 Duramax's gear selector lights stoped lighting up I drove it for a couple days. And then the ses light came on and my truck went into limp mode. The code reads Transmision sensor malfuntion and transmission hi out put. I read the posts about the nsbu switch. So i replaced the switch with a new tan one and the gear selector still does not switch, the ses is still on. I tried unplugging the batteries and restarting three times. Still no luck any suggestions on what to do next! Thanks Tony
