Transmission Faulty

I've had this truck in the shop 3 times for a shift issue with the transmission; it would have been more but I'm just waiting for my lease to expire so I can get a Ram! The transmission slams into gear at low speeds and the transmission won't shift so the RPM hangs around 4000 rpm until I let my foot off the gas.

Truck is a mess

I have a 2014 GMC Sierra Double Cab 2 wheel drive. I absolutely loved the looks of the truck but I have had nothing but issues since day one. The transmission cannot figure out what gear it needs at slow speeds and when it does it jumps and clunks underneath. I have a problem in the rear of the truck that when I back out of my driveway or hit a bump it clunks and bangs. The steering wheel sticks to the right when coming off the highway. When I took it in for repair they would not fix the problem because the could not get a repeat event. I have had several since then which is a huge safety issue. I have problems with rough idling at lights almost like it wants to stall. I have taken my truck in twice for humming in the rear. The first time I was told that it was normal. I returned it a second time and they replaced the gears in the rear end. I am starting to have the same problems again. My grade braking comes on periodically for about five seconds. I cannot even keep my coffee in the cup holder because of the intense vibration on the highway. So far I still have the same issues with 18,000 miles on the truck. I have tried to trade it in but I cannot get anything for it. I filed a claim with GMC and all I get is its taking some time because we don't have the VIN number. I have given the number twice to them so far and nothing. I will never buy another GMC. My next step is the better business bureau. I have been a GM fan for years but this truck is an absolute mess.

Transmission is HORRIBLE

my 2014 Denali 4x4 crew cab is a head-turner. Looks great, smoothest ride of any truck I've ever owned....However, the transmission is miserable. It's as if it can't decide what gear it supposed to be in at lower speeds. I guess I should have never left Ford

Nice truck, but the driveability is questionable

The Edmunds review does a good job of describing the trucks good sides. OK, now for the downsides. The throttle response on this truck is an absolute disgrace. There is a delay before your right foot's motion changes acceleration. That and the transmission's obsession with getting into the highest gear possible makes a sluggish combination during normal driving. A downshift sometimes takes several seconds! If this is all for fuel economy, I could possibly understand, but the economy, so far, isn't much better than the 2005 5.3 Avalanche this truck replaced. Maybe because I'm pushing this truck too hard trying to get it to respond to my right foot... Shoulda got the Ram...
please don't buy

I bought this truck brand new and it started running like crap. I traded in my Chevy Silverado for this truck. Worst mistake ever! The transmission trys to find gears and the whole truck vibrates at speeds over 60mph. I took it in to be serviced 3 times and still no fix! I will NEVER buy another GMC again.
