You can tell if the truck has the 6 speed auto tranny but looking at the gear selector, it will have the manual mode "tap shift" buttons.
As for tuning if your planning on upgrades (exhaust, EGR delete, tuner/EFI LIVE) I would go with an LBZ engine or older. With the 2007.5+ trucks there are more emissions equipment to deal with & if you live in a OBD II emisson testing state, altering the emissions will cause your truck to fail inspection.

Why do we keep posting the same thing? Is reading comprehension (as a whole, not the op directly) that poor?

lol, sorry. i was either posting at the same time, or didnt refresh when i asked my question. my bad.
lots of good info here and clarifying some misunderstandings i had. thanks, gotta find me a four door, 2wd 06/07 with a 6.5 bed and i'll be one happy mug
ok, about the bed sizes, posts #6 and #8 of this thread seem to conflict with #17, about what size beds you can get the duramax in. i did a little research, hoping i may actually contribute something as opposed to always asking, and found that the duramax, or any 2500 for that matter, only comes with a 6.5 or 8 ft bed. so... this is great cause i need the extra foot of room for my dent repair tools i haul around for work. good news, and the link below..

Correct. As i said in my posts and many have in there posts. Only beds u can get in a dmax are 6.5 or 8ft. Only way to get 5.5 in a half ton. If u want a dmax dually, its 8ft bed only.
