Transmission Problems? Ask a Mechanic for Answers ASAP
Assuming you are putting all the Cummins stuff in the Excursion that would mean the electrical system is going also that would mean you would need the pedal off the Dodge. Using the power train out of the dodge I would recommend using the electrical system out of the Dodge in order for it to work. I would imagine that both transfer cases are Strong and durable, probably real close to the same. Real good question.
