Question about Dodge Ram 2500

2005 dodge ram cummins diesel only getting 15 mpg

I have only been getting about 15 mpg for the last 6 months, I just had the automatic trans rebuilt and upgraded at the dealer about a month ago. I was continously getting 19-20 mpg around town, with as good as 26 on long freeway trips. What could the problem be, I have it serviced regularly at the same dealer everytime.

Check that the rebuilt box is actually engaging OD. Run fault codes and check it electronically. Have the bands and clutch packs re adjusted as the run in may have put the adjustment out a bit..

SOURCE: 2005 Prius change in MPG after dealer service

What was the weight of the oil that was put into the engine when it was changed? Prius engines are VERY PICKY about the proper weight of the engine oil. Trust me. I see this quite often. The wrong weight oil can do bizzare things, and def lower your mileage. Something you can check: Take off the tube leading to the throttle body, and look down into the intake. Do you see any oil laying in the intake manifold? If so, you DEF have the wrong weight oil. This will NOT set a Check Engine light, either. Hope this helps.

SOURCE: Charging problem on 1996 Dodge Ram 3500 Cummins Turbo Diesel

I had the same problem on a 94 dodge with the cummins. It seems the crank sensor that reads from a notch on the harmonic balancer was the problem Without this sensor reading that the engine is running the alternator wont charge. Possibly the same problem with yours

SOURCE: Trouble code P1740 on 1999 Dodge Ram 2500

I had the same code on my 2001 dodge 2500. The truck wouldn't shift from 3-4. I pulled the trans pan off and replaced a broken spring ($2.00). It is behind a thin plate with 3-4 small torq screws. You don't have to remove the valvebody. Only took me 45 minutes to fix.

I would like to give thanks to Jeff Russel from Teal automotive. He said this is a very common problem. He sells any part for any automatic Transmision and his prices are very affordable.

SOURCE: 2006 Ram 2500 Cummins inline 6 diesel -- fuel leak under hood

I'm no expert but I had a similar problem. On October 10th, 2009 I smelled the same thing. I own a 2005 Dodge Ram 2500 Cummins. It has about 150,000 miles. The next day I checked under the hood and found that the #4 injector tube was leaking and providing a fine mist of diesel fuel all over the engine compartment and firewall. The trouble seemed to be from the plastic clamp that is suppose to hold the tube in place. It was very loose and I feel that is the reason for the break/leak. The leak was right at the compression fitting on the tube where it passes through the nut that connects it to the injector. I called around to find the replacement parts and the dealer wanted about $75 for the tube and about $12 for the plastic clamp. I found the Cummins dealer wanted around $21 for the whole assembly and that included the plastic clamp assembly as well. Don't go to the dealer!!! I replaced the injector tube in about 20 minutes because it took about 10 to find my tool box. The repair was easy and everything is back to 100% fine and no leaks. I believe that if I had to replace injector tube # 5 or 6 it would have been a lot bigger deal because they are so far back and under the firewall. Difficult for someone without any more than standard wrenches. The only trouble I had was getting something of the proper height to stand on for good leverage. This one is a do it yourself and save project.

If I need a new transmission band, do I have to buy a new transmission?


There are no new transmissions

New- is only installed on the assy line one time

No --- you have to totally disassemble to get to
any bands,so you always rebuilt it

Just the removal from any vehicle, given how heavy
they have gotten, is a challenge

20 years ago even, it took two people just to put the
trans on the work bench & that was a 4 spd not 5,6 or 7

The only way you would need a band, is if the spot welds
broke on the ends

On a ford or dodge diesel, your best to highly modify the trans,
as they can't take the torque of a diesel, if you have large tires,
or tow

Dodge cummins tow haul stays on


Hi, I have a 2004 Dodge Ram 2500, 5.9 Cummins with 225,000 miles. Just today, my Haul/Tow keeps coming on and Trans/Temp light. Keeps automatically switching in and out on its own. It's been 100,000 miles since my last trans maintenance. Going to a mechanic close and he suggested to start with fluid change, filter change, and inspect the band, maybe adjust. Trans runs very smoothly. Checked the fluid, looks clean and not hot. Is this common with this year and mileage? If so, whats normally the out come? If the band is bad, do I have to replace the entire trans?

Is a dodge straight 6 diesel engine with 110,000


Yes, that is a good buy depending on price of course. A Cummins engine can run for 300,000 miles or longer. Generally reach the 500,000 mile mark with no major problems. There is a chance of an injector pump going out if it wasn't maintained well. I would buy it. I hope this helps please rate this and thank you

I would take it to the transmission shop & have it tested. My neighbor had the same problem with his 03 last month and we had to end up rebuidling it. Trans shop here retail price is about 2800, parts for good rebuild cost 5-600 depending which torque converter you get, & if you have yours rebuilt, get the good one. Rick
