noise help

Hey all, I have a problem that has been keeping my zj out of commision and I can not find the problem.
Problem being, when I shift into gear there is a short rattle, rattles when I drive (applying the gas) and when I put it back into park. All fluides are up, filters changed, to no avail. I will attach a video of me shifting into reverse then Back into drive.
Thanks for any tips in advance.

Jeep forum keeps crashing when I try to up load. Will try it from home in an hour.
Side note, when the jeep warms up the rattle stops
Rattle sounds in the area of the passenger side around the exhaust manifold maybe lower. Only one pers lol can't run throttle and dive down to listen fast enough.

Loose heat shield? Worn out Cat? Not the meow meow kind, emissions kind.

My ZJ has never been stuck, it was just taking a break from being so awesome!

haha got ya. no to the heat sheilds, i couldnt find any around to replace the ones i had to cut off of the exhaust manifolds, so i put em on without any.
As far as Cat, never thought of it. i was worried it was tranny or tcase or an engine knock. But noise is too far forward for t case. I will have to take a look at the Cat. I had a bad O2 sensor and never had EGR Valve hooked up for a month or so, so maybe it plugged it up.

It really don't sound like a catalytic converter rattle, that sounds like loose torque converter bolts, i would take off the inspection cover and look for rub marks, hopefully it's not an internal trans problem, it sound like somethings up with the flex plate/torque converter IMO.

Really hard to tell from the video, but it almost sounds like a pulley. Is it more noticeable from the front or back of the engine?

It's just a sheet metal cover attached with two screws directly in the center lower of the engine plate between the motor and bell housing, you can reach it easily just laying under the jeep. Take it off and inspect the torque converter bolts by slowly rotating the crankshaft, I think there are 4 nuts that holt the torque converter acessed through that inspection cover.
