Hey guys. I finally got all of the mods installed on my 00' Grand Prix GTP. Since the engine will be working a lot harder than if it was stock, is there any "special" or "extra" maintenance I should do to keep it running strong? Any advice would help out a lot. It's my first car and I want it to last as long as possible. Also, I bought it when it had about 112k miles on it and I'm not sure how the tranny fluid is doing. Is there anyway to check if it's good or not? I'm kind of a beginner with working on cars, so don't hesitate to give a lot of advice. Like I said, any advice at all would help out Thanks!
