well my wifes grand prix has reached 196000miles and I have seen a lot of metal in the transmission and since I have to take out the engine to get to transmission. I decide it is getting totally rebuilt.....and I figured everyone can talk(chat) about about upgrades and improvements that can be done to try and make this a "better" running engine. So if you can think of things that could be done please suggest it..like type of pistons or transmision clutches..
