08 3/4 ton Burb trans

[fishingwizard]

From everything I've researched, can someone confirm that an 08 3/4 ton burb will have the 6l80e transmission...?

Thanks!

I'm also on the hunt for a NNBS Suburban 2500. From what I've researched, 08+ have the 6L90E, not the 6L80E. They share powertrains with the Silverado/Sierra 2500 6.0Ls, which also gives them all the 14 bolt rear.

2007 Suburban 2500s have a 4L80E in case anyone is curious.
