For 2003 and the first part of the 04 model year (summer to Dec 2003), there were 3 different ratings for the Cummins:
- 235/460 = California
- 250/460 = standard output (2003 only)
- 305/555 = high output
In January 2004 (2004.5), they were all replaced by one 50-state legal engine rated at 325/600.
 
The TC will not change its lockup pattern unfortunately. For 2005, the calibration was revised and I have different shift points and lock-up speeds than your 2004.5, plus I have Tow/Haul instead of OD-off. (It would be a while before the 48RE was allowed to have both.) You can probably ask a dealer if your transmission software is up to date, although a reflash is not reversible if you don't like what happens afterward.

ALL I CAN SAY IS MAY GOD HELP YOU. I ALSO MADE THE MISTAKE OF BUYING ONE OF THESE TRUCKS BUT AFTER 7 CHECK ENGINE LIGHTS IN 6000 MILES AND OVER 2 MONTHS TOTAL TIME IN THE SHOP DODGE BOUGHT MINE BACK. APPARENTLY THIS BLUTECH 6.7 DIESEL WAS NOT MADE FOR THE AVERAGE DRIVER. THIS TRUCK HAS TO BE RUN HARD DAY IN AND DAY OUT OR EVERYTHING IN THE BLUTECH EMISSIONS SYSTEM WILL CLOG UP AND TURN THE MIL ON. GET RID OF IT WHILE YOU CAN. CALL DODGE AND REQUEST A BUYBACK. THEY BOUGHT MINE BACK ON THE FIRST TRY. I NOW HAVE A 2008 RAM 1500 HEMI THAT SERVES THE PURPOSE. GOOD LUCK.

cummns temp. by barrc_ranch

I have a 2002 dodge 2500 w/cummins auto, 4:10 rear end, 4 wheel drive, extended cab shortbed with 150,000 miles on it. everything works great like it should but when i take off from a light the temp goes up to about 210 degrees, after i cruise for a min. it goes back to normal (under 200) it never overheats or feels like it runs hot but it is bothering me. It also goes up to about 205 degrees stoped at a light with the air conditioner on idleing in the sun with no shade. If you are in the shade it doesnt affect it. On the interstate at 70 mph it is at about 2000 rpms and it runs at like 195 degrees which is normal in my experience.. If anyone has any idea on what it might be please let me know so I can take care of it.

My dad has a new cummins and has never had a problem. But he does tow a 35 foot cow trailer a least twice a week which dodge says need to be done with the new cummins or it will clog up the turbo.. If you want to keep it out of the shop tow a heavy trailer or load with it regularly.. If you dont have a trailer or something heavy to make the truck work I would get rid of it like the guy above and get a gas..
 
I have had a dodge hemi and it pulled my cow trailer full of cows all the time with NO PROBLEMS.. all the power you would need is there in the hemi. I just couldnt deal with the fuel milage or beating on my new truck so i got the cummins.
 
Best truck i have ever driven by far...

I have an 03 2500 5.9 diesel. Lately it takes more cranking to start and sometimes, not always, it seems to have a miss and valve chatter. The engine light has never come on, but definitely not running right. I changed the fuel filter, NO change. Any ideas???? Fuel ??? Timing ???

fuel spill by ramcharger

When I fill the fuel tank, excess fuel pours out over the tank. I got up under there and there are 2 hose ends with no hose. One at the front of the tank and the other at the sending/pick up unit. i found no lose or extra hoses any where. Got any ideas? Got any diagrams of the 2004 fuel tank and lines;

I don't know if my problem is the same. Usually won't start first time, but after a few trys (and just 'clicks'), the problem goes away and it starts all day. The solenoid is getting voltage but checking at the connector after the relay box, it takes a few seconds for the voltage to build up to 12 volts. I've cleaned connections, but obviously there isn't a broken wire, at least not yet. Does any of this ring a bell? Anyone else have an idea?

the cheapest start would be to check your vaccum hoses and the vaccum horn on the front axle. dont just look and see if they are connected, make sure they dont leak, as well the vaccum horn on the front axle could be bad.
 
good luck
