5.9 diesel dodge 3500 duel won't shift out of 1st red fluid is fine clean

Hi there Preston54. There can be a few reasons it is not shifting out of first. I would suggest bringing the vehicle somewhere to at least first scan codes and go from there. Further diagnosis might be needed afterwards, but at least we may be able to get a better idea of what is going on at that point. Give us a call at 847 352 2886, and we can try to set up a time where we can take a look at it. We are located is Schaumburg at 503 Lunt Avenue. If you decide to call ask for Mike or Scott...we look forward to hearing from you!
