In short I banged her up really good Inusurance sends her around trys to find out what's wrong and what it'll cost. So they determined there was no mechanical problems and fixed it. But weird thing my transmission goes right after that. They said the clutch blew out in it. Or burnt out. And they would have to rebuild/replace it. That was the first time.
Yeah the Chevy dealership did the work. But there "best".
The second time it definatly does sound like the "limp mode" your talking about. Since then I've had no problem with the beast. (knock on wood) A tune up is do and a new set of tires but that's about it.
