Calling all (the few) 6.7 2500/3500 Owners

I would like to ask current owners of the new 6.7 a few questions.

1) What type of gas mileage are you getting? Pulling or not.
2) Did you own a CTD before and what do you think of the differences?
3) How does it tow, and what are you towing? How does it do up hills with a load?
4)Is there anything that you're not happy with?
5) If you have an auto, what do you think of the transmission?

I can't decide between the 5.9 or 6.7 and the 0% for 72 isn't helping. I'd really appreciate any and all info you could give me. I'm not really interested in hearing from people who have test drove them, I've done that, I'd like to hear from owners.

Thanks.

1) Started out at 9 MPG now I'm at 13.5 MPG
2) I own a 98.5 24V - stock the 6.7 pulls better and much more quiet.
3) This truck tows awesome - it seems to have a lot more power with a heavy load - more boost maybe. The truck as about 5,000lbs on it every day, and I tow about 12-14,000 lbs every other week.
4) The only thing I don't like is that it is so low geared even with 3.73's. It has the G56 manual trans.
5) I drove a 2wd 3500 before I bought mine with the Aiasin 6 spd, I didn't like it - I'm biased though - manual all the way for me! The auto was alot more racey feeling than the manual.

Hope this helps - If you like to tinker with the motor get the 5.9 - if not the 6.7 is great.

I wonder if the fuel economy is going to be different from the cab and chassis to the regular 2500/3500 trucks since they are have different HP/TQ ratings would be nice to hear from some owners from that class.

Mnmlod, have you heard when your truck is getting here yet? I know ours got on the train the same day from NM mine is supposed to be here on 3/30.

You must remember that there are TWO entirely different 6.7s for sale by Dodge. The CC 6.7 (EB's) is designed to meet 2007 emission requirements. It only has a CAT and DPF and can tolerate some older fuel without damage. However, all the 6.7s put into Dodge pickups (2500 and 3500) are designed to meet 2010 emission requirements. This means that they have a CAT, NOx absorber (first vehicle in North America), and a DPF. Anything other than ULSD will be death to the NOx absorber (expensive!! all three welded into exhaust pipe).

The CC 6.7 has the stronger auto (Asin) and its version of the G56 has higher speed 6th gear. Mileage, and cost of ownership should be better with the CC 6.7 according to DC. Let's hope that Dodge really did a good job on the pickup 6.7 or new pickup owners may feel like ford 6.0 goats after a while.

I tell you what. There are a lot of reasons to go with a 6.7 and a lot of reasons not to. I just don't want to deal with the nightmare of recalls and really don't want a manual 5.9. I'm just concerned that the 4 speed auto won't be enough to tow a 14K toy hauler up the mountains in AZ.

Empty so far 14-14.8mpg mostly city type driving.

2) Did you own a CTD before and what do you think of the differences?

Got them all but, too soon to make an decisions. Throttle response is less than a 600. LOTS of emissions parts. Bombing will be more expensive. Potential should be higher for the average driver anyways. Exhaust brake works better than expected. Shifts a LOT. Truck seems put together ever so slightly better. Overhead console sucks worse than before buts has more function. I dislike the manual shifting but, you don't have to use it and for some it will be nice to have.
3) How does it tow, and what are you towing? How does it do up hills with a load?

Have not done enough to say yet.

4)Is there anything that you're not happy with?

Emissions equipment and complicated to upgrade in the future.

5) If you have an auto, what do you think of the transmission?

Seems to be ok but, once again sort of early to tell. The 6spd shifts a lot more but, it pulls less RPM at highway speeds. I think I can run 75-80mph under 2000 rpm. Tow haul is better but a little jerky when slowing down and it downshifts although with a load it may be ok. For the short term it seems to be fine.

I can't decide between the 5.9 or 6.7 and the 0% for 72 isn't helping. I'd really appreciate any and all info you could give me. I'm not really interested in hearing from people who have test drove them, I've done that, I'd like to hear from owners.

It depends on what you want. If you plan to leave it stock then it probably does not matter. The number of recalls out for it are very small at this time. I think in the future there will be plenty of parts for it but, they are going to be more complicated and because of that they will be more expensive. Can't say how expensive but, we will see. I highly doubt a programmer will work in the long run without extensive research, testing and inside information. I think the future will lie in plug in modules or add on enginemanagement type systems.

I think fuel mileage is better with the 5.9 and for good reason. I also think the fuel milage will be able to be improved in a cost effective manner in a relatively short amount of time.

If you are going to modify the engine or fueling very much an exaust system will be 100% mandatory.

Other than that they are the same truck with some different internals and dimmensions.

Thanks.
Hope that helps some? I will know more as the months accumulate!

Can you post what the 6th gear ratio is?? If that is true you should be able to buy that gear and put it into the older G56.

I think the pickup owners have got the shaft from DC with both the new auto as well as the manual. I'll bet the the CC manual is a version of the G86.

I've got a disagree that the C&C and PU have a different engine - I know that my C&C 6.7 has 2010 complient emissions or so says the engine tag. Could it be wrong?

Thanks Qzila. That's what I'm looking for. I really don't plan on doing anything to it as far as upgrades or mods. Maybe a small lift with bigger rims and tires, but no engine mods.

I am buying this truck so that I can pull a 14K toy hauler and just want to make sure what ever I get works the best. I really want an auto and I just don't know if the 4 speed will work.

Anyone else?

I just got mine last night after waiting for more than 3 months. It is a 3500 6.7, Auto, MC, 4x4. I just sold a ’05 Duramax, and I can tell you my first impression is very good. I have only 100 miles on it so far, but I can tell you that the transmission seems to work as well as the Allison. For a “stock” engine, the Cummins makes great power and torque. I prefer the feel of the solid front axle over the torsion bar suspension. The build quality on the Dodge is excellent. This is my first Chrysler product, I was a very loyal GM owner for 30 years, but that is history.

For now I have work to do, hitch, bedliner, level lift, etc…. I’ll report more feedback as time goes on, but so far, so good.

Check your exhaust pipe if it has a combined cat and DPF (cat smaller diameter than DPF) just in front of muffler you have a 2007 emissions package. However, if you have three separate cat like bulges before the muffler (Cat near turbo, NOx absorber next, and DPF just infront of the muffler) then you have a 2010 emissions package.

Also my C&C G56 w/3.73's has the 6.29 first gear, not the 5.94.

Those are the ratios listed by Dodge for the CC including the 4500 and 5500.
