New updates for PCM on all 6.7's.. I have been working at the dodge dealership and I also own a 6.7. There is a new TSB for a PCM update that is supposed to make trucks regen more often, or regen period. I have seen 4 trucks so far come in with "CATALYST STAT 100%" . Trucks are not regen'ing or the drivers of them stay in the city, and do not go fast enuff for long enuff to ever cause a regen. These owners come in complaining of no power, and we end up either manually causing a regen via using the starscan and going out and driving the trucks. On ones that we arent even able to drive (they won't move, have absolutely no power at all) we end up replacing the DPF and CATALYST. These are warranty repairs, but I believe its safe to say that the days of using a new diesel truck for a daily driver to putt around town are over. You MUST work this engine hard, towing regularly is almost a must. And paying attention to what the truck's overhead is telling you and reading the owners manual is something all new owners of these trucks must do.

 

I understand what you are saying from a technicans view, however there are many of us that bought there trucks to be farm and ranch trucks that idle alot, work in fields, hauling horses and cows, pick up hay etc. Are we suppose to get rid of there rigs unless were going to be on the highway and towing all the time?

The 6.7's are great pulling engines. However, if I would have done my research before hand I would have definitely got a 5.9. The problem is Ford, Chevy and Dodge have went to the DPF. Should we now be getting gas rigs for farm/ranch work?

I had my PCM reflashed at 700 miles (code 192) and it definitely fix the bucking/surgeing issue that some of us have had on occasions.

What a mess?

 

I'm picking up my new 6.7, 68RFE 3500 4X4 SRW LB SLT tomorrow and even with all the issues, I couldn't be more excited. I called the dealer to tell them I wanted the re-flash to the PCM that came out last week and they said they will be on top of it! This will have all the issues worked out before the warranty is over; I have blind faith.

Let's see if I'm proud to be a Beta guy in the next few years as all of my brothers and sisters on this forum who bought 6.7's seem to be.

The downside of this is........I traded in my 538rwhp 2004 Z06 Vette for this rig. My wife hated it..."It's too loud, it's too rough!" What a wuss....(well yes, she is). I loved that ride for those qualities and the ACCELLERATION!!!

I'm looking forward to be pulling a 3 horse trailer with a camper on my back and going up mountain passes here in Washington at reasonable speeds. I'm thinking my new Dodge 3500 is gonna do this.

Too bad I can't take my Ram 3500 out for early morning high speed twisty runs!

This is my first post.

"Remember, It's not the deal you're getting; it's the deal you THINK you're getting!"

 

I do not think that Cummins or DCX would release any truck that was not serviceable to the general public. Both companies know their users down to there shorts! They can quote bible and verse who buys what and why and its all backed by surveys taken at multiple events across these United States, Canada, Mexico and probably Europe. Do you think Honda and Toyota did not do there home work before bringing out there new truck line AND making their introduction in Texas, I think not, so with all that hot air please don't tell me that my truck cannot be a grocery getter/kid bus/mountain puller. All of the auto manufacturers are mandated by the government to meet 2007 EPA standards for diesel particulates and this means the 18 wheelers and the volks bug diesel and every one in between I just think Cummins and DCX do it better. My story and I'm sticking to it.

I hope your right Bigsnake, Cummins has always made an outstanding engines. The DPF is something were going to have to live with if we keep there rigs. Hopefully Cummins, DC or the after market will come up with technology that enables the DPF to clean the soot more efficently for short haul/use/farm work users.

 

At the present time my truck is dead. Died going down the hiway pulling about 20,000 lbs., won't start. That is all I do is tow, most of it on the hiway. The truck was perfect for the first 50k, for the last week it has been in the shop for 5 days. First they replaced a valve in the transmission, a hard code that had to be fixed. Then they did the famous TSB 18-038-07-Rev A. I was told that the regen did not start but to take it and drive it for 45 minutes anyway. I did and was told to take the truck home. Went to work the next day towed the trailer about 60 miles and the overhead came on with a message that said 100% full. I got my load and came back and unloaded and was unhooking my trailer when the cel finally came on, then it went off. I decided to take another job today because the overhead said 90% full. Drove 120 miles pulling the trailer, picked up the load and the overhead said 100% full and the cel was on when I started back. For sure had the power cut back, wouldn't even go up a hiway overpass without downshifting all the way to forth, normally with that load it will stay in sixth. Came back about 100 miles and it died. Got towed into the company yard and pushed the truck away from my trailer so the load can be delivered in the morning.

I make my living with my truck and can't take much of this. Love the truck when it is working, but I might have to find something else if this can't be corrected quickly. If the truck doesn't go there is no paycheck in my house.

nOne, you got any suggestions?

 

where can I find the TSB's for the 07's w/6.7L?

I'd like to have them do the flash, but wanted to have a copy of the TSB in case they him/haw around about doing it under warranty.

 

well, there isnt much you can do... Some trucks still arent doing regens even with the newest TSB (PCM reflash). DCX in the Denver Metro area drove 30 trucks, and decided on this new update as the best setup. They have had 3 trucks come back so far... So, its working on some, and not on others... As far as your truck not working because of 100% full Catalyst, you can only take it in and get a new Catalyst assembly which will be covered under warranty. This has been done to 3 trucks that i know of at the dealership i work at. When your truck was showing 90% full, you should have gone and tried to initiate a regen (60 MPH at 2k RPM) gear down to fifth for this. If the catalyst does not show that it is dropping down in percentage full, take it to a dealer, and have them hook up to it with the star scan and manually initiate a regen. This is all warranty too. They tell the computer to try a Regen and then go drive for 45 mins at the ideal speed/rpm which i stated earlier.. Thats all DCX has to offer for now.. Hopefully there is a better update/flash coming soon..

 

Geez these new trucks look like they are a PIA to operate. I can forsee recalls or huge waits for back orders on cat's and dpf's or who knows what else. You gotta love our government and the EPA for using their brain on this.

I thought any Dodge dealer could do a DPF clean out using a Cummins super duper vacuum cleaner. I am sure the dealers had to pay thru the nose for this special tool so why aren't they using it?

if you clog the DPF you normally kill all the sensors in it., And you can just wait 1 or 2 days and have a new DPF sent which is easier. They have been having issues with sending the wrong CAT/DPF because on the Cab Chassis its all one unit, where as on all the other trucks with the 6.7 its two pieces. So of course DCX has been sending two CATs or two DPFs instead of one of each. Just causes more of a wait time for the poor customer who needs the truck.

 

I was within inches of buying a new 6.7 a couple of weeks ago. Loved the way it drove and how quiet it was. But, something kept nagging me in the back of my head (and it wasn't the wife), so at the last minute I decided to grab that last 07 5.9 on the dealer lot. Man am I ever so glad I made that decision. I will wait 3 or 4 years before I consider the new emission laden equipment again. I wish you guys luck.

 

I have one of those, only 2k, never had problems and I don't have a clue when the regen process take place. It is too early but I never went back to the dealer. I don't know what to say other than the DPF is there to clean the soot from the combustion, could it be bad or wrong fuel for early DPF plugged up ?

 

I'm interested in a Megacab 6.7, but I think I'll wait until some more of this kind of stuff gets sorted out. From what I have read on dieselplace and dieselstop, the Fords and GMs are having their share of issues related to the new stuff too.

I just hope this 6.7 doesn't turn into a 6.0hno...
