'99 5.2L clank/rattle?? Video included!! Thanks

Hi, I have a '99 Durango with the 318ci Magnum engine and 44RE trans that has a really bad clank/rattle somewhere around the oil pan/bellhousing area? The noise seems to go mostly away when any throttle is applied, and it is mostly when idling (usually anytime it is below 1000rpm it will). The Durango has about 141k miles, but the trans was replaced at 110k with a reman'd trans. I have been on the XJ Tech Forum for a long time and trust JF a lot more than other forums, and since the 318ci is the the same engine as the ZJ 318ci I figured someone would know what this is...

A few people have told me that it sounded like the timing chain was loose, so I replaced the timing set this last weekend. And that did not correct the clanking/rattling noise.

And for some reason I am having issues posting YouTube, or Photobucket movies, so I'll try both lol

Any ideas? Bump? I've had someone say that it possibly sounds like the flywheel bolts? And of course, there isn't an easily accessible inspection plate.....

So when it is in Reverse, or Drive, the clanking goes away pretty much? Only when it is in Park, or Neutral

Alright, well I figured it out! Lol its a cracked, or loose, flexplate. So today I am going to try to access the inspection plate and get the final answer

I didn't see where the other bolt went, let alone the fact that I can't see if anything else got damaged from it probably rolling around the bell housing. None of the bolts seem to have any thread lock on them even.

So I figure I am going to just save the money and get a new torque converter, flexplate and bolts. Sound right? Any recommendations on brands of torque converters? I have was thinking about getting a higher stall converter while I was at it, something around 2000?

The thing that really sucks is that I purchased this truck about 10k miles after a reman'd trans got put in, and I think that they must not have used any locktite. I guess I'll have to look to see if its under warranty still!? Probably not......but worth a look.

I know absolutely nothing about automagic transmissions. If it breaks, I take it out, put a new one in, torque it down, and slap the vehicle on it's *** as it leaves. I would pull the transmission and check EVERYTHING.

Well.....no warranty coverage so it looks like I am going to have to install it myself. Now I just need to learn how! Haha

I did some research and found out that I want a 2400 stall speed for my 318 to match my torque numbers I guess. So I was looking at getting a Pro-King torque converter after reading a few reviews. But does anyone know what other seals I will need to do it right?
