Narrative:

What I believed caused the problem is the way in which the flight plan is printed. If put in the FMC as printed it is not current when there is a transition involved as the computer generated flight plan shows aveto 8. Dvc awd does not say dvc transition therefore the FMC when programmed as per the flight plan terminates the aveto 8 at aveto and proceeds to dvc and not via the transition when it is programmed in to the computer just as stated on the computer generated IFR flight plan. I feel this problem could be avoided if the computer generated flight plan showed aveto 8 dvc transition, then the filed routing and FMC routing would agree.
