Thanks for any help on 5. 9 HO ECM and auto 48RE TCM question, DG8,48RE, for 2006. Going to dealership tomorrow to shop nationwide for remaining '06's, 5. 9,3500,SRW,Reg Cab,4x4,long bed,auto, my work truck. Got a '07 luxury truck few months ago and want to be sure a '06 offered to me from long distance away on dealer trade is really the same 5. 9 HO ECM and 48RE TCM as my '07. Been saving $$$$$ a good long time for these retirement big ticket items and was just a tad late on the 2nd order and dearly want only 5. 9's. If is 2006. 5 (build date Jan. 06-Jul. 06) then I'm thinking pretty sure it's exact match to my '07. Will be doing "sit-down" with Seattle dealer first thing Friday AM. Thanks to all. Jim.
