I am really interested in what you are doing because mine was installed two weeks ago by a dealer and after they had my truck for 3 days called me and told me they discovered it would not work on the 2005 48RE. So now have brake but cannot use it until Cummins comes up with the software fix for the 2005 Auto. The guy that installed mine is at this e-mail address: -- email address removed -- and I am sure he would respond to your questions as he seems like a good guy and knows his way around the cummins, however he works for the dealer and was the one to do the install on mine. They read the part number from mopar as 2004. 5-2006 and 2006 Automatics to mean it included everything from 2004. 5 to 2006 models, a honest mistake and I read it the same way, however once they started the install they did not read the installation manual first which clearly states it is not for 2005 Automatics. How do you plan to get it to work on your truck? The mechanic told me he could wire it to work in a manual mode for me but I would have to be very careful to switch it off when the transmission got to hot etc. , however Chrysler customer serice center scared me when they said using it that way could effect the warranty on the engine, since I only have 37,000 miles on it, so told them not to hook it up and am waiting for Cummins to come though now. Good luck and I will be your biggest cheerleader for getting it to work.
