2015 Sierra transmission ahhhhh!!!!

[kiwihiwi]

My truck (2015 Sierra 1500 slt) made a loud clunking noise underneath, revved up the engine and now only drives slow, I can push the gas pedal all the way down but it only drives slowly. Engine light is on, d light blinks and manual doesn't lock in. Revers works but the backup camera doesn't turn on. On star read the issue as transmission issue with power loss but I didn't get any specifics. Dealer is closed until tomorrow. Help!!!!

It doesn't sound like you are making it any better.

 

"Dealer is closed until tomorrow."

I guess you'll be waiting until tomorrow then.

Boooo!!!!! No hints or tips on what it could be??

Had to park it somewhere, couldn't leave it in the middle of the road ;)

When shit like that breaks down you take it to the dealership or to a mechanic, seems like some sort of mechanical failure, we're not AAA, we can't help ya bud.
