What transmission is in it, still a 5speed?
If so it easily could bewhat was posted above or it could be related to the manual valve and the PNP switch which is on the TCM/VB.
This is what tells the transmission if it is in either Park or Neutral allowing the engine to start along with what gear is selected for the TCM and so on.
This is a very crucial step for anyone who drops the valvebody or is even doing a rebuild on the bench as it has to be done in perfect order and is sort of an awkward angle to be able to see when seating the VB.
I will try to upload two photos from the ATSG manual so you can get an idea.
At any rate it isn't something I would be looking into if you are under warranty and it is that new. Hopefully you are able to get them to take care of it for you or put you in a new truck.
