Hi I'm new to this forum..I recently bought a 2006 Chevy cobalt Ls coupe. It has 112k miles on it. When I take it out of park it jerks and also jerks from 1st to 2nd gear and gets lighter as it goes but the first two are pretty jerky. Does anyone have any ideas? The tranny isn't slipping or making a whirring sound. I'm lost. Any help would be appreciated!!!
