RPMs when Shifting

I have a 2009 automatic. I noticed that when shifting from 1st to 2nd gear, the RPMs barely drop. At all throttle levels, they barely drop by 100-200 RPM. I read that all Cobalts have the 4T45 transmission which from here -

GM 4T40 transmission - Wikipedia, the free encyclopedia

I see has 1.82 between the first and the second. Shouldn't the RPMs be dropping by a lot more?
