Th350/np205 help!!!

Hey Guys,
So I just replaced my TH350 with a TCI Unit along with torque converter. This tranny is their truck/4x4 version. I also replaced my tranny mounts on the adapter plate and my Torque mounts on the NP205 with Poly mounts. Tranny runs and shifts as it should. I have new u-joints as well. The flex plate was fine when I installed the tranny. The adapter was also fine and not cracked when I installed it.

The problem is when I come to a stop or stop sign I hear a clunk coming from around my transfer case area or tranny area. It sounds like something is shifting forward. If I put my hand on the 4wd shifter I can feel it happen. There is no play on the drivelines. This has got me completely puzzled on what happened when doing the swap. Is it possible the torque converter or flex plate bolts came loose? and there is play there? How would I know if my adapter plate was now cracked?

Any help with where to start would be great.
Thanks
Matt
