Default New GXP Owner needing advice

Hey everyone, just traded in my '99 GTP for a 2008 Grand Prix GXP, 73,xxx miles. So far from the digging and looking on it, seems to be bone stock. So my list of upgrades/to do's start now. I could have swore I saw a list on here somewhere of recommended upgrades, but cant find it. I live in Iowa so temps are anywhere from 0 degrees to 100 degrees. Any and all information would be fantastic!

Thanks!

Dan

What is the opinion on Dex-Cool? In my gtp, I had it slushed and put Green in. Do the same with the 08 GXP? Or keep running Dex-Cool? Also, drop the pan and change tranny fluid and no flush? Just wanting to get these things out of the way as the car is new to me so I want to know its done right.

Thoguht?

Thanks!

^^^this also if you get the coolant flushed. You have to make sure every little bit of dexcool gets removed before you put in green coolant. The two don't interact well with each other.
