Well, i just spoke with the service guy at the dealership. They finally got it to mess up. He said they have been on the phone with GM multiple times today and have no clue what caused it. He says it may be the selonoid or valve body but they arent sure, it hasn't created any trouble codes. They have compared data with other trucks and nothing seems out wack. He says there are no tech bulletins out about this issue. He referred to it as "flaring" and not slipping, more of an extended shift. So i guess now i just wait......just my luck

They must be the only dealership that doesn't know what it is. Maybe they should look it up on the Internet. It's a software issue, it's been said elsewhere on the Internet that GM does indeed know that there is an issue.
 
Run far away and find a new dealer.

hey jbickham, I have a 2012 silverado 5.3L 6 speed 4x4 Z71. my truck had the same issue. At 5k i finally had enough and took it in. Dealer rebuilt the transmission and said that 2-6 seloids were damage and the valve body was scored. Take it back and have them ispect the valve body and selonoids. After it was rebuilt i lost 3 gear towing my jet skies. I took it back and had the transmission replaced around 8k. They know the have a problem with these transmissions but wont do nothing about it unless you push the issue. Dont take these B.S answer and have them fix it. I ended up calling the chevy customers assistance to resolve the issue.

That is the exact truck i have. The truck is still at the dealership. Ive dealt with transmission issues in a new Mazda we bought in 2003 and learned that being nice gets you nowhere fast. We ended up having that vehicle replaced under the lemon law. Im more than ready to battle with these folks. I just really hate that this is going on with my truck. I absolutely love it. Thanks for the info.

Well, exact other than mine is a Sierra...but same thing. Did the transmission replacement fix your problem? And i'm curious to know if anything is different internally in the new vs the old transmission.

Lady3bglover, How do you register your vehicle online with GM?

after the transmission was replaced it has worked good. Its been about 5k since the replacement. My truck now has 12k on it and it has been working good since then. I will know for sure once the summer comes again because thats when i tow around my jet skies. the way i explained it to the tech was it felt like the clutch was staying engaged for about 3-5 sec longer than it should. Bad enough if i gave it gas i was reving the engine and not moving.

jbickham,
I am unsure if Lady3bglover is talking about this or not, but if you were to visit https://my.gmc.com/web/portal/managemybrand?g=1 you could set up an Owner Center account where you can keep track of service history, check into recall and warranty information, and so on.
 
All the best,

Sorry to hear that you're still working with your dealership on your truck, jbickham. If you wanted for us to check into this further with you and your dealer, please email us at socialmediagm.com (include your name and contact information, the last 8 of your VIN and mileage, the name of your dealer, and a brief summary of the situation).
