lol i'll join this since i'm also new to the GTP "mod" world. This is my first car a 97 GTP coupe. I've heard things about the transmission in the Grand Prix and if you add too much horsepower you can hurt the tranny. I have some mods lined up to add around 60-80horsepower and just replaced my tranny (cough) next time you get your tranny flushed stay there and make sure they do it right. So since it's brand new i would like to know if adding such horsepower would cause further problems.
