Ok I repaired the plenum, while working on it the key was switched on and smoked the braided ground from engine to body ( the ground from battery to motor was disconnected at the time). That was repaired but now the truck only indicates when it is in P or N, when I turn the key on and check the gauges all indicate correctly. I have replaced the TRS and that did not fix it. It is giving code 1899 & 442
