Default Rattling from transmission tunnel

It seems that within the past 2 weeks, a rattle/tap has developed (at idle and shifted into gear but no throttle). It sounds like ****. It cannot be heard outside of the car. I put my ear to the transmission tunnel inside the car.. that's where it's coming from. Tranny shifts as smooth as ever and goes into gear no problem.. The only thing I can think of that could have caused it was when I had my flexplate replaced (well over 3 months ago and has never made a peep till now). What could be the cause of this rattle?

I have a solid welded x dumped at the axle. No fittings, clamps, etc.

Nobody knows? It's gotten progressively worse and now vibrations can be felt on the pedals.

I would look at the ta mount, at least one person on here has had on fall off.

The other thing that I just found on my own car was the the bolts that came with my new poly mount were just a touch too long keeping the mount from being secure on the crossmember which made my trans sound and feel like a rock tumbler.

well, you need to crawl under the car and ck stuff, shake the converter, flywheel to see if its loose, give the trans a good look all around it, its just normal stuff you have to do to run down the problem
