New 2018 Sierra All Terrain owner!

[Austin718]

So just bought my 2018 GMC Sierra All Terrain. She’s Dark Slate Mettalic and I’m so glad I picked this color. But I just started having a transmission problem at 2700 miles...

 

i threw her into 4 wheel drive for the first time in the snow last weekend and now every time I start her up it clunks shifting from first to second.

 

Took her into the dealership and they said it’s what GM calls acceptable, pretty pissed about it. I’ve read other forums on it I guess I’m the lucky 1 out of 100.

 

Still love the truck just really wish this clunking wasn’t here. Anyone know if there is an update coming soon???

Welcome to the forums! Too bad to hear about your tranny issues already, doesn’t sound very acceptable for that to be happening this early
