The truck has 56k on it I have had the noise since the second week that I had it.
I also just got the complete service record for the truck the previous owner had the truck for less than one year and had multiple problems with it including a drone or vibration, they put new transmission in at 1200 miles thats about the time I got stuck with it. thats less than 5600 miles per year GREAT QUALITY hu!!!
between the dealer and the other repair shop they have put 3200 mile on the
truck this year. And the dealer says nothing wrong with it even though it shakes
the filling out of your mouth. The other repair shop has not charged me yet and
is getting pissed off they can't find the problem yet they have asked GM to send
there gurgu to look at the truck he wants 350 and hour.
which is interesting since they would not do it under warranty.

A guy on another forum had this same issue and the dealer diagnosed the drivetrain was out of alignment. They realigned the transmission and driveshaft and the problem was solved.
Might want to mention this to the dealer.

I have a 2013 Silverado Extended Cab that vibrates right at the shift point between V4 and V8 mode - between 1100 and 1500 rpm, 40 to 45 mph. Dealer says vehicle is operating as designed and that he can do nothing to fix it. I can't believe that GM puts vehicles on the road that have this issue. Does anyone know of a fix?

Ask the dealer do a test drive on a similar model on the sales lot. It will be quickly established whether he's blowing smoke or not.
Call the GM customer service line in your owners manual and file a complaint. They could refer you to a more accommodating dealer.
As your current dealer is telling you....live with it.

There is a fix-it's aftermarket. This device cuts off the AFM. Owners have reported no significant mpg loss. Some have reported a slight increase in mpg.

Check the transmission Forum. And believe it. They do "put em' on the road!
Since at least 2010 when they began to appease the Feds and increase "CAFE (fuel mileage) standards" in return for the TARP Money, GM has been very aware of the AFM and transmission complaints. The growling, lagging, thump-"what-the ....-was-that" complaints etc.
#270 of 272 2004 Silverado 1500 4x4 front end vibration
Aug 01, 2013 (11:31 am)
I am getting vibration and humming from my front end that increases with speed. It does not affect the steering (it's not wobbling). Took it into Big O Tires and they realigned the front end, and said the wheel bearings are fine. This did not solve the problem, it's still there and seems to be getting worse. They said it was the sound of the tires. This is not the tires. It seems to stop when I turn to the right, and I think it is affecting power also. I've seen several posts for something similar, has anyone ever found a solution? I want to know what I'm talking about before I take it in for repair.

I'm thinking it has something to do with the differential. There appears to be solidified oil that has been leaking and flowing back toward transmission.
