The dodge dealership said we needed a pcm, so we replaced it. Now, the transmission wont shift out of low gear. The pcm has 3 missing pins. Will this effect the transmission? I'm thinking we need to get a replacement pcm. I just don't know what will be effected by the missing pins

Did the original pcm have thee missing pin, they may not be missing they may be left out in engineering, as far as the trans not shifting, was the pcm reprogramed because if you just installed out of a box it unlikly that it will shift
