Should just be two plugs on the side of the tranny. An upper one(for filling) and a lower one (for draining)
Also here is a link you should look at before getting any fluid

Thanks for the posts. I just feel the transmission fluid has been in there for 4 years going on 5 and if I was a transmission I would want fresh fluid. Specially in a performance car such as the Cobalt SS Turbo!

Took a pic today for ya. Its really the only one i could get, and it was just cause i was doing an oil change and remembered to do this lol
This is on the drivers side of the tranny. The red arrow is the drain plug, and the green arrow is the filler plug.

Very helpful picture. So I hear people buying 2 quarts of the transmission fluid (OEM part # 88862472) but it only takes about 1.7 quarts. I feel however how much fluid comes out of the transmission, I would put that same amount back in. I also see other posts of people saying to take the drain plug out, let all the fluid drain out, then fill it till it starts leaking out of the drain plug. I thought you would have to fill it past the drain plug or how would it drain in the first place....?

The service manual says to also coat the threads of the plugs with high temp thread sealant. Tighten to 37 ft-lbs. I'm changing mine this week because the retarded dealership used the wrong oil in mine and it shifts like ****.
