2015 GMC Sierra All Terrain stutter at takeoff...wont go!?

GMC207 · January 31, 2016

Just wondering if anyone has any experience with my issue so when I goto the dealer I might have more info....

The past few days when I am say at a stop light and hit the gas to go it wont go, it like stutters and loses power. Even when the gas is down its like its stalling and then itll snap out of it if I clamp it.

Anyone have any idea? Any advice?

As expensive as these trucks are they should come with a warranty for times like this.

It does. Im asking so when I got the dealer I can maybe better explain whats going on and share how others dealt with it.

Could be low on transmission fluid. Have you checked it while the engine is running and warm?

Directly from a stand point of not having enough information for the dealer. Try changing things like turning traction control off. Then try manual mode on trans just leave it in M6 and see if things changes things. Post your results so others may have a idea before heading to dealer. My dealer will actually have me try things on the way over so they have a better understanding of what's going on.

I have a problen similar to this. I'll start my truck in the morning and it will warm up for 10 minutes. Back out of my driveway and I'll shift it to m5. I hate the AFM. Once I give it gas, not a lot, it acts like it doesn't know what gear to go in or kinda stutter and feel like its towing something....meaning I should be rolling quicker with the given throttle. Once I'm rolling it seems fine but say I'm at a light its not as bad bud still feels like its deciding on what gear it should go to. I've read there is a tranny software update or something to that effect. Once I go for my free oil change I have that and a list of things I want checked/ done.
