you cant go wrong with oem. mobil 1 5w30, dexcool, etc
owners manual will tell you standards that have to be met but wont mention mobil 1 by name. there are only like 5 or 6 oils that GM has tested that meet the standard they set for your engine. Mobil 1 is what it was filled with from the factory (some argue that the engine was built around that oil specifically). as far as tranny fluid, it depends on whether or not it is a stick or manual. the manual used to require ATF but i read a TSB that called for something different now. I used Amsoil TQD for my manual and Amsoil for the differential but that is just personal choice. you can download the owners manual and it will tell you everything you need and there are multiple write ups on here about how to change everything. just gotta search around.
