2010 Chevy Cobalt 2.2L is Accelerating Way Too Fast
2010 chevy cobalt auto 2.2L. Car has been great ever since we bought it until about 3 months ago. We started noticing problems with the car shifting hard when putting the car into drive and when the RPM get up to about 3grand. Fast forward to now, the car still shifts hard when going into drive but now, just going 20-40mph the RPMs jump up to 4-6 grand and it's making crazy noises. We just added new fluid and some tranny leak stop about 1-2 months ago. I would include more info but at the moment I'm trying to check the fluid to make sure it's still in there. Any info or advice would be great. I just want to keep my family safe with my wife working nights 30
Miles away driving the car alone in the middle of the night.
