6.7 diesel how good?

[bulldog426]

how good is the new 6.7 diesel? are they as durable as the good ole 5.9?? is there certain years to avoid? how are they on fuel mileage??

Just a little bigger. They do require a good run at highway speed occasionaly to clean out the particle trap if you do most driving at low speeds.
Their fuel mileage is lower than the 5.9 by some. The Aisin automatic tranny alone would prompt me to buy one.

the enigine is awsome. there was a lot of emissions concerns at first check engine lights. looks like they have that all taken care of. with the last few computer updates there have been less and less in our shop. the 6 speed 68rfe trans in the pickup is a very good trans,. so is the as68c in the cab and chassis . fuel milage is lower due to the regeneration system.
