grinding and clunk in trans?

hey guys i got an 04 SS, and recently within the last 1500 miles, i noticed a clunkng type deal goin on, front passenger side checked the entire front end, replaced that axle and tie rod end on that side since my other impala had a similar issue and it fixed it, but anyways noise is still there mainly when pulling away not to heavy on the gas and when coming to a quicker stop, other noise that is worying me that is leading me to belive its in the trans is the grindinng noise i get in reverse i can idle backwards and give it a real little bit of gas and it does fine,m but anything more than that its a nice heavy grinding almost sounds like something is binding up, when i pulled the axle out of that side i tried to peak around in the housing a bit with a flashlight and didnt find anything my trans fluid was done about 2k ago when i did my shift kit, my fluid already seems a little burnt and i didnt get anyfluid leaking out of the hole when i pulled the axle? fluid level is good in trans but i also had just that one side jacked up a little on the higher side, but i figured some fliud would leak out since thats how it was in my other impala, is there anything that would restrict fluid from getting in by the differental? there is one thing that might be vibrating up on the car and that is the down pipe for my headers, but i dont feel that it is because of where the noise is coming from, imma gonna wonder over to the trans shop someday this week and have them check it out and see if they have any ideas, car has 67k on it and it shifts terriffic real smooth and quick and is still turning both front wheels, so im kinda lost looking for some much needed input from the fellow impala lovers out there
thanks in advance

I'm not sure what it is, but immediately noticed a correlation when you said the problem started 1500 miles ago, and you put in a shift kit 2000 miles ago. I would expect its somehow related.

actually got outta work early enough today and took it to a reputable trans shop around here and first thing guy said its something hitting the underbody, but tomorrow im going to go under and look for marks or signs of parts making contact and maybe drop the pan and check everything out my fluid smells burnt again as well so who knows, seems once i hit a point the stuff burns up in a couple weeks or so fluid was fresh at 60k when i got it and burnt up and redid with dex6 and now within few thousand its burnt again so i dont know, so we will see

There has got to be a reason the trans keeps getting hot enough to burn up the fluid, I kinda wonder if it isn't something with the torque converter. Especially with the grinding and clunking you describe...
