Probably a dumb questions once I can figure out where it's located, but I can't see where to add transmission fluid. I need a flush, but holding off for a few weeks until I get back to school, wanted to add some fluid in the meantime to help with the shifts.

First off, is that a good/bad idea? Secondly, where do I add the fluid?

Most cars I just pour it down the spout, but I can't even find one on this car, let alone where to check the fluid levels.

Also, is standard ATF fine, or do I need that dex-con stuff?

Not a dumb question at all, I went through the same thing also wondering, where in the hell is the dip stick? Went and got a Haynes manual and sure enough, certain model's do not have a dip stick but instead a CHECK PLUG located near the pan, adjacent to the engine drain plug. Place a container under the check plug and remove it. Observe the fluid as it drips into the pan, indicating correct fluid level. The fluid level should be at the bottom of the check hole. Make sure the vehicle is LEVEL. If no fluid drips from the check hole, add small amounts of fluid through the vent/fill cap at the top of the transaxle until the level is at the bottom of the check hole. A LONG NECKED funnel will be necessary. GM states that routine checks are not necessary, unless there is an obvious leak. Something that was once very easy to check has more less became a pain . Had my fluid and filter changed anyway's at the 50,000 mile mark. As for trans. fluid, 2005 models Dexron III, for 2006 and later, Dexron VI.

I think I will just opt to take it to a shop and get a flush. I am just experiencing some rough shifting, and some issues when trying to drive up steep hills when heading out of town.

Thanks for the reply, good to know I am not crazy because I couldn't find the dipstick lol

Try checking your Air Filter, cleaning your MAF sensor and your Throttle body. I've heard of people having issues when trying to drive up hills and such and it turned out to be some dirty parts. Although a tranny flush will probably help as well.

Just cleaning those parts are easy simple things you can do at home.

Thanks for the tips, I replaced the Air Filter today, going to clean the MAF sensor after work. Will plain old maf sensor cleaner work on this type of sensor? I noticed the G6 has a thin flat sensor, sort of unusual IMO.

Going to clean the throttle body today as well, taking a 300 mile trip this weekend so I am hoping for some improvement.

Any MAF cleaner will work on the MAF. And any intake or carb cleaner or tb cleaner will work. If you have a plastic intake manifold you could even remove the TB for a complete clean and reuse the old gasket. But if u have a metal manifold then the gasket is likely paper and would require replacing if removed.

But I pulled off my TB and really got a good cleaning out of it, felt great afterwards.
