I used your guide to install a Tru-Cool 30,000 transmission cooler with a thermal bypass rated for 180°. I figured I wouldn't need a 40,000 since I live in Ohio and I went ahead with the bypass for the winter. Had to improvise here and there, but I was able to get it done with all of the same supplies that you used for yours. Trans temp never even gets up to 180° now, even after driving for 2 hours back home and thirty minutes of that being driving in the city.
I bought my first Grand Prix for myself 5 years ago when I was 18. Loved the Grand Prix ever since and the GXP essentially became my 'dream car'. Now that I finally have one I'm hoping to drive it as my every day car for at least the next 10 years.
Your guide is very well detailed and very informative. I wouldn't have even attempted to do this myself if I hadn't come across your guide. I can't say thanks enough man
