Have a '08 Dodge Ram 6.7 w/ 6 speed allison tranny. consistent mileage 10 non-towing-9.7 towing. Particulate filter clogs, check engine light on, have had needed wrecker service twice, So many service bulletins out the tech said there wasn't enough paper in the dealership to print all of them!! although he would be happy to let me read them on the screeen. Anyone else having problems with this engine?

You don't have an allison tranny with that truck.

There have been some problems with the 6.7.

If you go here: http://www.dieseltruckresource.com/ there are tons of 6.7 owners that have most of the issues worked out.

Good Luck.
