Sounds as if the PCM doesn't know it's in Drive.
Transmission Range Sensor?
the pcm doesnt do much with the trans except to tell it when to upshift based on speed and rpm inputs , so the range sensor would have nothing to do with it , all the range sensor really does it tell the pcm when the trans is in park or neutral for starting , other than that , if the trans is in drive and the pcm sees a change in vehicle speed and rpm's , that pcm is perfectly content , plus if the pcm didnt know it was in drive the truck would not move at all and obviously he is driving it
