I actually have my 2010 GMC Sierra at the dealership now, although we have different issues with the truck it is also with the transmission and the dealer's mechanic drove it and noticed the problem. They are saying that we have a lazy transmission, the mechanic said that it has a learning transmission, but they are baffled why it does not know why it does not know when to shift.... I kind of feel in the same boat that we bought a 44,000 dollar truck and don't know what the problem is or how they can fix it. We had a 2005 Chevy Hybrid before this and had no problems until the 5 years were up. Then the big problems set in. Since it was electronic in certain areas such as steering we lost sterring going down the road and the truck was running, but we also had shifting issues with that truck as well, this is a first year for this transmission so if you find out anything before we do PLEASE let us know what your issue is, we already asked the dealer to see what the trade in value for this truck will be so that we are not getting another lemon. Good luck with your issue glad to see that we are not the only ones that are dreaming that this is happening,

#713 of 1523 2010 chev Silverado 4x4 whining
Nov 19, 2010 (5:01 pm)
has anyone experienced a whining after shifting from 4x4 to 2x4? This has been happening since I got the truck and no one at the dealer seems to know why. We've taken out other trucks and they don't make the noise. We've had the transaxles apart and no sign of wear. It drives me nuts as it gets worse in the colder weather. If you move the 4x4 shifter back and forth just a little sometimes it will stop. It sounds like the front axles haven't fully disengaged.
Thanks for any help

You most likely have the classic brake fluid leak from the bottom (at the sensor) of the brake fluid reservoir
The fluid leaks down into the wiring that impacts the CC and other electronics.

This is a brand new truck, no leaks just one really irritating noise. I've hit a wall with the dealership as they can't find anything wrong. They can hear it, they can go out with me and we can make it happen and then like I said you move the 4x4 shifter just a bit back and forth and it's gone. Till the truck sits and then its back again.

I too have a 2000 Sierra 4x4 that did exactly the same thing. It seems Sierra problems are the same across the board. I also have the same problem as someone else noted about when the tranny gets heated up, approx. 100 miles, the upshifts hit very hard. I now have 208,000 and something that just started the other day; when I accelerated to pass someone, the rpm's went soaring up, but the truck wouldn't do a thing. I'm suspecting the tranny is shot unless someone tells me otherwise. Thought about upgrading to a newer GMC, but the problem blogs scare me. Maybe I should just keep replacing parts. It's still cheaper than a new truck payment. Be prepared!

It could be forward clutch piston, also check and make sure you are not leaking brake fluid from the master brake cyl. on to the wiring , if so you will need to repair the brake cyl. and use electrical cleaner to clean off the brake fluid !!!
