2009 Chevrolet Suburban LTZ 1500 4dr SUV 4WD (5.3L 8cyl 6A)
Just traded in an 07 on an 09 suburban and pleased with the six speed transmission. The 07 had a four speed transmission (I think the 08 year had both but on different models) and the shifting is much smoother. It also finally has blue tooth. Other than that, it is the same truck as what we had and we were pretty happy with it.
