1999 dodge ram no start
ok long story but here goes nothin. started off driven done the expressway lost tranny fuction. got towed back home thought i had a bad tranny. went to push it into to the barn and it started and drove into the barn so i tried to see how far it would last. got about a 30 secounds of playin around in the driveway lost tranny function again. so i turned it off and started it back up and everything was fine again so it did the same thing again thought i had a wiring issue. so i checked for codes with an mt2500 and got no comm for data and codes kept changing. so i checked other modules and got the same thing. so i unplugged the pcm and tried again. i regained info from all modules exept trans. so i checked power and ground at the pcm all was good. so i ordered a pcm programmed for my truck. finnally got and plugged it in. now the truck wont start and the insturment cluster has no bus. if i unplug the pcm it starts and drive down the street with tranny in limp mode but wont start with new pcm. i put the old pcm in and it starts fine. im runnin out of ideas and could use some help.
thanks
