I am looking at a '97 Dodge 2500 Cummins with 160000 miles. It has an automatic transmission, Pac Brake, Magnum Force air filter, straight-piped, otherwise pretty basic, simple truck. I wondered if there are any typical issues that I should be careful about in considering this truck. Is this before the "53" block problems? Is it after the "Killer Dowel Pin"? Or are these or any other problems likely to exist in this year? What should I consider doing to the auto transmission to beef it up for snow plowing? Thanks in advance.
