Cummins 6.7

[cj41foley]

Anyone heard anything on this motor and new 6 speed auto tranny? They have pretty good rebates on the 07's right now. Just thinking.

thats what I was wondering, thanks

word I've been hearing is anything new with some type of particulate filter is getting terrible mileage. I haven't heard anything about the new dodge trannies but I'm sure the new cummins is just as stout as the 5.9 was... Also has a VGT charger which I'm told is a pretty good design... It'd be a heck of a set up if it wasn't wrapped up in a dodge.

I've heard some guys are having reliability issues.

The 6.7 has got to be stouter than the 5.9, they bumped the rear axle to an 11.5 from a 10.5, and I'm sure they wouldn't have done that if they could get away with it...

Are we not talking about the new Duramax's because they are way better or are we forgeting about them?

Haha, I made that comment the other day when I heard about my friend having to take his new Cummins into the dealership for a major repair with less than 10K miles.

"Who would have thought we'd get to the day where the Duramaxes are the reliables ones!!"

Make no mistake, there have been some Duramaxes that have had some problems too. They seem to be doing the best but they are still imperfect. A local guy had his in for a new #5 injector and dpf.

Mileage in all these DPF/emissions equipped trucks is all over the board. I have seen guys report high teens to near 20, and others report single digits in ALL 3 brands.....so that comment holds about as much water as a bucket that had the bottom cut off.

Thats true the mileage is all over the board with the DPF, but out of everyone in know with a 6.7 granted thats about 3 people. The best any have reported is 13 mpg.

Ahh, sorry I was just on the dodge site earlier, and to get the 6.7 they force you to select the 11.5 axle... I'm sure it was an option in previous years.
