Transmission Fluid?

Does anybody know where the to change the transmission fluid on an 08 Cobalt sedan? There's nothing in the owner's manual, and I couldn't even find a dipstick. Is it hiddn under the cover or underneath the engine? Thanks in advance.

There are some posts floating around. The AT used is the GM 4T45E. They haven't had ATF dipsticks for years. There is a top mounted, threaded fill cap and a level check bolt at the top of the pan flange aiming towards the pass side front wheel. Check your manual, but I believe they use Dexron VI ATF, which is semi-synthetic, thus the 100Kmi change interval spec. Here's a pic I mocked up some time ago:
