I have a some questions. I just found a 2002 Ram 2500 with a Cummins that I'm looking at possibly buying. I'm going to drive it this weekend. It has 102,000 miles on it and it's an auto. I know that the engine is perfectly fine with the mileage but what about the transmission? And is there anything else that I should look for? The dealer is asking $18,800 for it. I really don't need a different truck, (I have a Chevy HD gas), but I'm really itchin to own a DC.
