First off, I have to say that I am impressed with the 68RE auto. I had a LBZ Duramax before this truck & this tranny seems to act better than the Allison did ( I was surprised too). As far as the emissions crap goes, she should be fine driving it on the highway. If she just drives around in the city all the time then yes she will have problems. Another thing that makes a big difference on these trucks is what flash the ecm is running. Dodge has had to reprogram the ecm several times since these trucks came out. The latest flash that I am aware of is the AQ flash. I had to have mine reflashed back in June. After the flash I went from an average of 14 mpg to between 16-17, hand calculated. About 2000 miles ago I unplugged the egr motor & am now at 17 riving like I usually do, or if im nice I have gotten to 19 mpg, hand calculated on the highway. I miss the tuneability of my duramax, but like this truck a lot overall. If you have any other questions feel free to ask.

 

Uhhhhh.......take it all of and get the fooler boxes. Then you'll expierence 22 mpg.

 

Do the turbo clean yourself and get the H&S DPF delete for 600$ 2100 bucks, man I would of donkey punched that a$$wipe right there!

 

The new 2008 6.7L engines includes few upgraded firmware that is better than what I got on my 2007 truck. But even what I got has been decent to me. I say, tell her to go for it. I had one sensor go bad and my filter filled up. But it was easy to clean the whole exhaust system.

About the auto trany 68AER : It is one of the best ones out there now. It is better than the Alison on Chevy's.

Also, she always can shift the trany to 5th gear if she is not going faster than 55MPH, in order to get the RPM up and clean up the soot in the DPF.

 

Thank you guys so much, this sounds like a perfect match for her! She's all excited and shopping around now! LOL

I'm really surprised w/ the tranny being I drive the Dmax Alli combo - Good for them! I always liked the Cummins but was afraid of the auto trans, I'm glad they got it together and hope they do GREAT with it!

Thank you all again, you've really helped me! Now I just have to convince her to let ME play with it...

( I love this forum and all the smileys! The people are cool too though! )

 

I'm not sure this has been pointed out but the new cummins is not, i repeat not a grocery getter. it must be worked or it will be problematic. the DPF uses 13L of fuel on each regen that it will do should it not reach operating temperature for a period of time - which unfortunately I don't have the spec on. Anyway, short hauling is not a good thing with this motor. If she is pulling that load she shouldn't have a problem but then again, I may be wrong.

 

Wyatt; You are correct on that. Short distance driving is equal to asking for problems. This is a work truck, it is not meant to be a Sunday truck!!!!!

 

well ? i think she'll love the truck alot more if she get's rid of the emissions gear(dpf,egr,egr cooler) and depending where she is put a engine/cab heater in cause she's a gurl ans well i recommend that every diesel has one? but thats me ,,she'll be fine and love her truck,cause i do love my truck espeacialy after i did all that ,,,i get awsome fuel econemy and for my power wow i love this blue demon,and for the i'll refrase that for buddy a few threads back a "68rfe" it's awsome to for what power i am running now ?? now of coarse if i want more power i will upgrade my tranny for that reason ?? but for now its gggrreat ?? buddy tell her to get one and do the deletes and she'll have no worries ???
