04GTX,
If you are planning on doing it to your '04 I don't think it is possible because the 04's don't have a separate computer for the transmission like the 03's. Check out some of the other posts about the TMR mod...I believe that has been mentioned.

 

will this work on my 2002 ram 5.9 or am i out of luck cause i would put a switch on it to turn it on and off when im gonna use it
