2010 GM Pickups With 6 Speed Automatic

Does anyone own a 2010 GM full size pickup with the 5.3 V8 and 6 speed automatic transmission? What is your opinion of the new 6 speed automatic transmission?

Was the 6 speed automatic offered in 2009?

Our 2007 NNBS (new new body style) 2500HD has a 6 speed automatic. You must be looking at a 1/2 ton if you are looking at the 5.3 engine. That trans is most likely different than ours. From what I have been hearing is the new 6 speeds are very durable but they do shift some what strange. At times ours shifts like it has some sort of harsh shift kit in it. I think in 2009 is when they started offering the 6 speed in the 1/2 ton trucks but I could be wrong.

Yes, I am talking about the 6 speed automatic they use in the 1/2 ton trucks.
