So I am new to the whole Cobalt world as I just purchased a 2007 Cobalt. It has just over 11,000 miles on it and an automatic transmission. I have one question, and hopefully I will make sense. Say I am driving down the road in the final drive gear and I give the car a little gas (enough to make the car drop a gear for passing but not flooring it) the RPM's start jumping up about 500 RPM's and back down until I give it a little more gas does it finally downshift. It's as if the car wants to downshift but hasn't decided that's what it wants to do. Like I said hopefully this makes since. I am going to bring the car to dealership soon but I just wanted to see if someone here knew what this was all about before I head there. Thank you.
