I have a '93 Dodge 2500 CTD with a 5 speed that I am using to plow snow. The truck plows great, but the manual transmission is not the best system for plowing snow. I want to sell this truck and upgrade to a newer truck with an automatic. I have heard that there is a certain block that I should avoid. How do I identify that engine and which years was it found in? Also, which year auto transmission would be the best to hold up under snow plowing? Thanks. JH
