Al (Ram01Bigal): 2006 is the earliest with auto trans that can accept the exhaust brake and keep warranty. Manual trans - no problem -- in fact recommended highly; I again, today, called and spoke with tech here who told me that 2 problems exist for me - the main shaft into the trans won't take the stress placed on it by the exhaust brake and the 2nd is that the main computer doesn't have enough memory to hold the program needed to do the lockup etc.... the 06 models come with upgrades to both that allow for them to have an exhaust brake installed for the 48RE transmissions. Once again, mentioned that I could trade to a newer truck -- but given dealer incentives / employee pricing going on right now, no way can they give me anywhere what I think I deserve for my O4.5. Life is rough
but almost time to go camping
