If you have a CTD that is newer than 2003 then you cannot use an EB with a 48RE auto transmission until 2006 or 2005 with the upgraded programing. If you have a stick shift, you can add an EB any year. I would add the EB first. It will make a whale of a diff in the way you drive. I had one in my 1997 auto and 2002 6 speed. I dont have one in my 2004 but it has the 48RE transmission and the "Tow/Haul" feature really works well for me. If I ever decide I REALLY need an EB I will put it in and take my chances with the thrust bearing wearing out. I hope that helped.

I do have a 2005 3500 with a six speed. The salesman at LV Dodge said "most people my age get the automatic". That almost killed the deal. I'll file your number and thanks for the response.
