Default no bus code

hello everyone! i have a 1999 dodge 2500 24 valve cummins. recently my truck displayed a no bus code and i lost all communication from my gauges and truck wont shift out of 3rd gear, so i took it to the dodge dealership near me and the scan tool/programer that they have cant connect to any of the modules there is no communication between my computers or my gauges but my truck still start us fine and runs,we have checked all grounds and connectors, and over the last 2 years of chasing down this problem my pcm/ecm have been replaced and fixed the problem for about 30 miles and everything goes back to no bus and nothing working. i have also changed my ctm. I stopped by today and they are reading that there is voltage going through everything and that the guages are reading that everything is on but nothing is talking to each other, and i have not put any tuners or chips in this truck!! any help would be appriciated to help me figure out what is wrong with my truck thank you!........
