If you combine Chevy and GMC pickup truck sales for 2011 they come pretty close to Ford. While I respect your taking time for the test drive, obviously, based on the numbers sold and the number of posters (last count 15ish) who say they have problems, most people are not finding a severe problem that keeps them up at night.
Congrats on GM for selling large numbers against new redesigned Ford F150!
P.S.-I just returned from a trip after Christmas from Salt Lake City NV to Southern California. I make this trip often, and I decided to let the AFM "do it's thing" and keep the cruise control set to 70mph. Consequently, the truck achieved 21.2 mpg between Mesquite NV and the Inland Empire portion of Southern California where I live. That was very impressive. (2011 Silverado Crew Cab w/5.3).

I just wanted to make sure that you are not experiencing any current concerns? I would be happy to assist to the best of my abilities if you were.

Ok so i am 17 years old and my transmission just started having problams this morning when i drove to school. it has 250,000 miles on it and the transmission was replaced at the dealer when my parents bot it new at the dealer 16 years ago. my dad drove it off the lot with a new after market allison 4 speed transmission and it has been in the family ever since and i drive it every day and when i drove it home last night it drove just fine at highway speeds and then this morning the transmission wouldnt shift any gears at all i could only go 20 and then it would rev up and im wondering if anyone had any suggestions on what i should do repair costs are not an issue but please give any and all suggestions

I would say take it in to a trans shop for a rebuild. That might cost more than what the truck is worth.
#1157 of 1523 5.3 liter Six Speed AFM clunk bang slam lag growl steering pull on and on..

In addition to the clunking banging slamming growling lagging steering pull A/C defrost cycling off, since new; my new 5.3 liter six speed with AFM (now) won't clear the message Washer Fluid Low Add Washer Fluid from the Driver Information Display. THE TRUCK IS LESS THAN ONE YEAR OLD, MORE PROBLEMS?
Not to mention the brakes squeal and the synthetic oil turns black 1000 miles after oil change?
ANOTHER trip to the Dealer. More than 9 in only 9 months of ownership? I'll use the term some of the young guys at work use; "are you kidding me man"!
More widespread new Sierra Silverado problems? In addition to the 5.3 liter Active Fuel Management and transmission clunking banging surging slipping complaints that are all over the internet, the DIS fowls up in less than a year also?
Yup, that's what I bought a new GM truck for. So I can average a trip a month into the Dealership for quality problems to hear "it's operating as designed" it has to adjust to my driving habits" again.
Terrible quality GM. Just horrible.
If you're considering a new Sierra or Silverado, test drive it for long periods in the mid 40 MPH range with the Driver Information Display on "Instant Economy." Listen for clunking , growling , lagging etc.
Lotta guys complaining about the lack of quality in these newer GM trucks. Don't just look at the new GM transmission complaints, look at all the newer complaints. The Crew Cab guys and thier noise issues on other sites etc.
Specially' since the TARP money bailout and CAFE standards increase in 2009. The two seem to coincide with many of these GM truck quality control complaints.
Even the CEO of this website, Jeremy Anwyl, cautioned the FEDs not push new CAFE standards on the automakers and the North American public.
Maybe GM was trying to appease the FEDs by pushing these unproven drivetrains too quickly with "clunky" results and widespread complaints?
My New Sierra = Terrible Quality.
And, like many, many new owners, Terrible GM Customer Support.
Every time you enter a Dealer or talk to Customer Service, tell them how disappointed you are with the drivetrain/powertrain. Keep it at the forefront. I'm going to.

"Not to mention the brakes squeal and the synthetic oil turns black"
I sent you a link for this on an EXTENSIVE oil information site that says this is normal.
If your going to continue to complain, at least keep it real......

This is REAL!
Both dealers that I have taken my truck to (4 times) tell me that they and GM are aware that the six speed transmission and the AFM have problems that need to be corrected but, they have not come up with the answer.
Last service rep says his manager drives the 5.3L with six speed and has told him it sometimes feels like it is going to "throw him through the windshield". Welcome to my world! Yes Chuck, this is a complaint.

I have never said the 6 speed is the smoothest power train in the world. The post I cited above has proven to be a complaint without basis because the poster is dissatisfied with his truck.I cited a link which proves what exactly dark oil means. In addition, at times all brakes will squeak, regardless of the make or manufacturer.
This is exactly what has caused me to get involved in this board. Either outright lies or half-truths.

If you're considering a new Sierra or Silverado, test drive it for a long (flat) run at 45 MPH with the Driver Information Display on "Instant Economy." Listen for clunking , growling , lagging etc. Ask the GM salesman if the "AFM" should be seamless (my salesman bragged about it). "Instant Economy" display will show the truck move from 4 to 8 cylinders in the mid 40 MPH range. Judge for yourself if the transmission is a clumsy mess. Or, if the AFM is actually as seamless as GM says it is.
Ask the Service Manager, not the Sales Manager (mine is/was a purveyor of "bovine scathology"), if GM is receiving much "negative feedback" regarding the 5.3 liter six speed with Active Fuel Management. Ask him if there are any "internal GM directives" instructing the Dealer on how to deal with all the complaints regarding the six speed transmission.
And, most of all, GOOD LUCK! With the enourmous amount of complaints and GM's non response of " Operating as Designed " and " It has to adjust to your driving habits" regarding the same issues with these new GM trucks, many of us have had bad "luck"!
