My 2009 tahoe LS Has had no issues what so ever but today it decided when I started it up it was vibrating and the service stability control and service traction control and the traction control light is on and when you drive it doesn't want to shift at all I have to punch it so It will shift. And then when I am driving it bangs into gear and jerks forward I'm just stomped the dealership is closed today so I can't take it their can you please help me????

 

Sounds like the same thing my 2007 Suburban did when it was miss firing due to oil consumption issues. It would have some minor vibration sitting still, after two minutes of idling Service Traction Control and StabiliTrac would pop up on the dash. When I started moving it would bang hard into second gear.

 

Mine is still doing it but yesterday it started up fine and no vibration issues what so ever I'm so tired of this first my jaguar and now my tahoe this is not my week
