Cracked Flex Plate?

I didn't check that but will sounds like a rattle and clunk and grind all together but still goes away

Yeah, check the flex plate real good. You may have a cracked one. They can make some really strange noises when they are on their way out and you DON'T want to let it go until it comes apart.

Well I can't seer nothing wrong with flex plate so I took the dp off still has a noise so I guess I'm gone pull the trans and see if my noise Is motor or trans I'm gonna be mad once I do it and find that it's something stupid simple

Does the truck make this noise in all gears? Reverse, Neutral, etc?

Yes and park just idling it will go away when the engine has a load

I really wish I could get a video Of it doing this I've parked it for now and am driving my other psd with 15" of lift and 42" tires to work I hooe it's simple

Thanks guys I found the noise the flex plate is completely broke in 2 pieces atleast it wasn't the engine 342000 miles so I can't complain to much

Wide Open Performance has cyro treated flex plates available if you want to go in that direction.

Thanks but I had a extra one my 97 crew cab 4x4 started as a auto and I tore the zf5 out of another 97 I got and put in it so I had a spare e40d and really a whole spare parts truck I got 3 of these things really wish I could post pics for yall

what year is the truck with the broken flexplate?
