that sure looks like a 6l80e to me, and the 799 heads along with the block number give it away as a 5.3 gen IV engine

The numbers in the last photo indicate it's a 4.8 engine. I'm pretty sure GM starting mating the 4.8L engine with 6L90 transmission starting in 2010 in vans & pickup trucks.

You need to find a tag or laser etching on the rear of the block just below the head on the driver's side to confirm.
