Low torque/power

[granduer]

Ok guys here is my problem. I have been noticing that my 2006 DRW 3500 with 22700 miles and it has been losing the ability to pull my loaded dump trailer, 8k to 10k. I have been losing fuel milage also. I took it to a very good transmission shop and they tell me that this truck is very sick but its not the transmission, they suggest taking it to dealer to have it checked. So I take it to the dealer and they tell me that there is nothing wrong. They said it was not throwing any codes, and that they put it on the computer and again found nothing. Does any one know of any TSB's or any other things I can do to get to the bottom of this.

Have you changed the fuel filter lately? Whenever I have any driveablity problems, I change the ff. So far, thats fixed it everytime!

No I haven't but I will now. Thanks for the heads up. I will let you know if this helps.

The Dealer would have never thought of that.....



Check for codes yourself, turn the ignition key on/off three times, on the third time leave it in the on position, any codes present will show up in your odometer window, write them down. If no codes are present it will say "done".



Codes will show as P0743, P0753, P0336, etc. , there is a list on the 3rd gen forum explaining all the codes.



Make sure your air filter and fuel filter are functional. Dealers..... ?
