your welcome badbob,the codes are basically for fuel control and 02 sensor issues. and I don't think they have anything to do with the truck not moving,it should move,maybe run like crap but move none the less .have you checked the fluid level in the trans? if it is ok? then you may have a severely clogged trans filter or a internal transmission issue

you may have a bad pump,or a valve body issue.i would suggest that you take it to a tranny shop for a diagnosis.
