How sure are you that it is the tranny making the noise, could it be the cat converter shield?

my '51 Chevy had a rattle that got me looking under the car quick, it did it in any drive gear ( D L or R ), turned out it was just a muffler clamp that I had taken out of use ( the mount it was holding onto wasn't needed after I raised the exhaust more due to clearence issues ) but it was rust seized togther even without bolts ( and was loose ) and I forgot to remove it then , and when the car went in gear, it would vibrate it making a bad rattle that made me think the trans was having the fits, looked under ( car still in reverse, but not moving ) and saw it ratteling, got back in, put the car in park, shut it off, grabbed an air line and the die grinder with a cut off wheel, and zipped it off, then went back to what I was doing with the car.

make sure it isn't an emblem on the side of the car... i responded to one earlier and that was what it turned out to be... but i would check to make sure there aren't any shields loose as well as possibly the torque converter bolts...

The 700R4 in my project 34 had to be removed because of a rattle in park. I could not hear it until I got the exhaust installed. I called the fellow over who built the 700R4 and he put his ear to it. His estimation of the source of the noise was a band rattling. When he pulled the trans apart again he discovered excess clearance. I am not quite sure how excess clearance in a band assembly could account for a rattle only in park. Perhaps Crosley could fill us in.

I can't remember if you will have the cable or linkage setup for your shifter, but, if you have linkage, check to see if it is making your noise. Lube up the pivot points and frame mount and see if this helps.

I had a couple off road trucks that did this, and the transmission to engine bolts loosened and on occasion fell out.

Kind of difficult to put locks on them bolts as they are hard to get to, so I went to a schedule of checking them once a month. And it didn't matter on the lock washer type I tried to use either, beat the truck hard enough that even they backed out.
