I thought it would get louder with rpms if the flexplate was cracked? also its intermintent thats what gets me one day it wont do it at all next day its doing all the time at idle??? just a real screwy thing if it was constant i would think the flexplate but its not. Also i noticed the frequecny of the ticking gets worse if i rod the hell out of it? not sure why it matters but it does maybe ill try recording the noise when it does it again
wouldnt matter. the cracked part may be stuck stuck one day, then open up the next. if you put it in gear, it may be puttin enough torque on it to push teh crack part onto the TC to stop the clicking.
My money is on the flexplate too. might try gettin under the truck when its clickin in park, put the end of a decently long screwdriver on the tranny bell housing and put your ear on the other end of the screwdriver (preferably the blunt end
), it will work like a poor mans stethascope. so you should hear a decent "click" through it ASSuming the sound is transfering through the bellhousing as well
