Yeah I added the 3 dbcs to my core and to my client. (to the local as Ladiszlai said)
And I can link my gameobject+transport : http://pastebin.com/G83RSYwD
The only issue there might be is VerifiedBuild=0. I am not sure what that field is for at all (well, it seems to be revision number), but 12340 is most commonly used - thats for WotLK 3.3.5a. I always used 12340 or 1, but I have never actually used 0 for that field. Its possible that thats the only one thing which is giving you problems. Change it to 12340 and if that won't fix it, I will need to take a look at your DBCs.
