Rough dying 2003 7.3

[chrisr892000]

I was wondering if anyone had some input on this problem ive owned my 7.3 now for around four years its running around 117,000 miles about six months ago the truck started having a real nasty sound when turning it off. its like a rough loud clanking sort of noise coming from underneith the truck sounds like around the starter or bottom of motor but ive ivestigated it and cant come up with any thing on my own. the truck has always turned off smooth as could be i cant figure this out but from the sounds of it you know it cant be good. any help would be greatly appreciated ive stumped myself on this one.

Auto or manual transmission? Get under it and have someone shut it off, pinpoint the rattle between engine and or transmission.

Big rigs will make noises like this, it's caused by the clutch rocking back and forth....So as noted above - auto or manual?

ile have to get out there tommorrow and see if i can pin point that area. it is an auto with a 4r100 i had it rebuilt last feb i installed a ts 4 pos chip and within alittle over a year it had the tranny shredded. since the rebuild i havent put it back on and had no problems so far but i guess the noise could be coming from down there ile see what i can come up with

Check the inspection cover on the tranny. It could be loose. Something a little deeper. Could have a cracked flex plate.
