never posted before but i figure it’s worth a shot. i have a 2002 dakota 3.9 v6 2wd with an automatic transmission. last week when i tried to start it i got a no bus code. the engine would crank but it wouldn’t stay on so i ended up replacing the pcm and the idle air control valve. the truck is now running but now it won’t shift out of 1st gear when i drive it no matter how much i push on the pedal. any suggestions on what to check next? i was told the crank sensor could be an issue but i took it out and the wiring wasn’t frayed.
