Sounds like my ticking is normal. The whine is not the planetary gears in the transmission. It changes with throttle position. It sound alot like a vacuum leak. The dealer said it is not. That is why they drilled a very poor looking hole in my muffler. Still whines like a turbo does. But now it had a loud swoosh when you give it gas. Kinda sad a truck that costs nearly 50k gets hacked at a GM dealer and then send me away saying they will call if they figure out a cure. I called GM customer service, I am still waiting as they keep sending me to a different person. They said someone from GM would call today. Never did. They got my money and that's what's important. My truck only has 2000 miles and I gave up a perfectly good Toyota for a lemon. Oops.

I don't think it's the fuel pump. The ticking is a dull ticking more toward the engine. The turbo sound goes along with the rpm and light throttle. I thought it was a vacuum leak. They say its the weep hole in the muffler. I am going to plug it completely and see if the whine goes away.

My new 2014 silverado sounds like it has a loud turbo whine under light acceleration. Started at about 1200 miles. It is loud enough to turn heads. Took it to the only dealer in 100 miles and they drilled a hole in my muffler to enlarge the weep hole. Now my truck has a nasty looking hole, a whistle and now a swooshing sound. They ruined my exhaust. I use to like this truck!! They say they called GM and there is no fix. I don't know what to do. This is not normal. It also has a ticking sort or sound at idle they try to blame the injectors. You can hear it 100 feet away! GM wonders why they are not selling. It's not the trucks. It's the service from the dealers when you have an issue
