i might soon be buying an 00 v6 with a procharger supercharger, high perfomance clutch, mac exhaust, chip...the guy says the only thing mechanically wrong with it is that when u go from 4th to 5th there is a sticky sychronizer?? and it sometimes grinds, he said all u have to do is when u shift from 4th into 5th drop it into neutral first then into 5th? does that sound right? or is it somethign more? also, he said with the high performance clutch it kinda shakes going into first but after u break it in it will stop, again, does that sound right? help me out, thanx
