I have an 01 Dodge 2500 with the Cummins 24 valve
and auto transmission. I have replaced two lift pumps and one main pump
under warranty and have just went through having the transmission overhauled at
104000 miles. Earlier, I had a torque converter failure. Other than
all that, I love the truck and it has all the power I need to run in cruise
in hilly country. I suffered through a variety of gas powered trucks prior
to this one and I will never go back. The torque curve of the Cummins is in just
the right range to do a wonderful job of pulling. I pull a three horse
goose neck with living quarters and usually have two horses aboard plus all the
gear. It doesn't even know it's back there.
